Description

Title of Invention : HEAD-MOUNTED DEVICE

Technical Field

[0001]
The present invention relates to a head-mounted device that is used by being worn on a user's head.

Background Art

[0002]
An example of such a head-mounted device, which is to be worn on a user's head, is a head-mounted display (hereinafter referred to as HMD). Such an HMD is equipped with a display device such that the HMD can show a user various videos.
[0003]
Such an HMD is suitable for applications, such as covering a user's field of view by using a video, showing a user a three-dimensional video, and showing a video that follows the position or movement of a user. However, there is a case where the position of an HMD worn by a user is displaced due to some factors, such as loosening of a mounting portion. In this case, an offset video will be shown in the user's field of view, and as a result, may cause discomfort. In addition, if the degree of offset of the video is increased, there is a case where the HMD cannot be used.
[0004]
PTL 1 discloses a measure for preventing the above-described displacement of an HMD from occurring. A head-mounted device disclosed in PTL 1 includes a display unit that displays a video, a contact portion, and a string-shaped member that connects the display unit and the contact portion to each other. The length of the string-shaped member can be adjusted and maintained, and the string-shaped member applies pressure to a user's head by generating tension between the display unit and the contact portion. The display unit is securely positioned with respect to the user's head by a frictional force generated as a result of applying pressure to the user's head. This secure positioning can prevent a video from being offset.

Summary of Invention

[0006]
As described above, according to the head-mounted device disclosed in PTL 1, secure positioning can prevent a video from being offset. However, regarding the size of a user's head, since each individual has a different size head, a suitable length of the string-shaped member varies in accordance with the user. Thus, in the case where a plurality of users use a head-mounted device in turns, each time another users takes a turn using the head-mounted device, the length of the string-shaped member needs to be adjusted for the user, and consequently there is a probability of such a user-switching operation becoming complex.
[0007]
The present invention has been made in view of the above-described problem, and the present invention provides a head-mounted device capable of facilitating a user-switching operation which entails a plurality of users taking turns to use the head-mounted device.
[0008]
A head-mounted device according to the present invention includes a display unit that displays an image to a user and a head-mounted unit that is capable of being worn on the user's head. The display unit includes a first coupling portion that is used for removably coupling the display unit and the head-mounted unit to each other. The head-mounted unit includes a second coupling portion that is used for removably coupling the head-mounted unit and the display unit to each other and an adjusting unit that determines, by adjusting a shape of the head-mounted unit in such a manner that the head-mounted unit fits the user's head, a position of the display unit with respect to the user in a case where the display unit and the head-mounted unit are coupled to each other.

Description of Embodiment

[0011]
The configuration and functions of a head-mounted device according to an embodiment of the present invention will be described below.
[0012]
The head-mounted device according to the present embodiment includes an image-capturing unit that captures an image of a physical space and a display unit that displays an image (a video) to a user. The user has a line of sight view via the image-capturing unit and the display unit. Regarding the specific processing to be performed by the head-mounted device, first, the head-mounted device obtains a real-space image captured by the image-capturing unit. Next, virtual objects (computer graphics and the like) and another real-space image are superposed on the obtained real-space image as necessary. Finally, the display unit displays the image, which has undergone the superposing processing, to the user. Note that, a real-time video can be displayed to the user by performing the above-described processing at sufficiently high speed. Specifically, the head-mounted device may be used for development in which components are evaluated without manufacturing the prototypes of the components, drills for disasters that rarely happen, entertainment, and the like.
[0013]
On the other hand, the present embodiment can be applied to a head-mounted device that does not include an image-capturing unit or a display unit and that stimulates sensory organs in a user's head excluding sight. For example, the present embodiment can be applied to a sound-guide device that provides audio guidance for users with visual impairments or to a head-mounted device equipped with a device, which artificially generates smells, and the like in order to increase the sense of reality of a virtual object.
[0014]
Fig. 1 is a diagram illustrating the appearance of the head-mounted device according to the present embodiment. The head-mounted device in a state where an image-capturing-and-display unit 100 and a head-mounted unit 200 are coupled to each other as illustrated in Fig. 1 will hereinafter be referred to as the head-mounted device in a head-mounted mode A. The image-capturing-and-display unit 100 includes the image-capturing unit and the display unit and serves as a main body of the head-mounted device according to the present embodiment. The head-mounted unit 200 is capable of being worn on a user's head. The user can observe, by wearing the head-mounted unit 200 on their head, a display of the image-capturing-and-display unit 100 without placing their hands on the head-mounted device. The image-capturing-and-display unit 100 and the head-mounted unit 200 are removably coupled to each other, and the mechanism will be specifically described later.
[0015]
Fig. 2 is a diagram illustrating the appearance of the head-mounted device according to the present embodiment. The head-mounted device in a state where the image-capturing-and-display unit 100 and a hand-held unit 300 are coupled to each other as illustrated in Fig. 2 will hereinafter be referred to as the head-mounted device in a hand-holding mode B.
[0016]
In the hand-holding mode B, a user can observe the display of the image-capturing-and-display unit 100 by holding the hand-held unit 300 and bringing their face into close contact with the image-capturing-and-display unit 100. Note that, as in the case of the head-mounted mode A, the image-capturing-and-display unit 100 and the hand-held unit 300 are removably coupled to each other.
[0017]
In the present embodiment, the image-capturing-and-display unit 100 and the head-mounted unit 200 are removable from each other. Similarly, the image-capturing-and-display unit 100 and the hand-held unit 300 are also removable from each other. Since a common mechanism is disposed in a coupling portion in which the image-capturing-and-display unit 100 and the head-mounted unit 200 are coupled to each other and a coupling portion in which the image-capturing-and-display unit 100 and the hand-held unit 300 are coupled to each other, in the case where a plurality of users use the image-capturing-and-display unit 100 in turns, the users can easily take turns by only mounting and removing the image-capturing-and-display unit 100 on and from the head-mounted unit 200 or the hand-held unit 300. In addition, if a common color, symbol, or the like has previously been given to the coupling portions, the users can smoothly perform a user-switching operation, which is an operation for taking turns, without problems. Furthermore, if a plurality of head-mounted units 200 have previously been prepared, and each of the head-mounted units 200 has been adjusted so as to fit the size of the head of a corresponding users, it will not be necessary to adjust the tightening force of the head-mounted unit 200 each time one of another user takes a turn. Therefore, according to the present embodiment, in the case where a plurality of users take turn to use the head-mounted device, a user-switching operation can be facilitated. Specific configuration and mechanism for realizing the head-mounted device according to the present embodiment will be described below.
[0018]
Fig. 3A is a perspective view of the image-capturing-and-display unit 100 of the head-mounted device according to the present embodiment. As illustrated in Fig. 3A, the image-capturing-and-display unit 100 includes a front cover 140, a rear cover 120, and a cable 150. In addition, the image-capturing-and-display unit 100 is equipped with the image-capturing unit (not illustrated).
[0019]
The front cover 140 is formed of a transparent or translucent member. The image-capturing unit captures an image of a physical space in front of the image-capturing unit through the front cover 140 and obtains a real-space image. In the case where an opaque member is used as the front cover 140, image capturing can be performed if a hole is formed in the front cover 140 at a position in front of the image-capturing unit.
[0020]
The cable 150 is used for supplying power to the image-capturing-and-display unit 100 and performing data communication with the outside. Note that the cable 150 can be omitted as long as the image-capturing-and-display unit 100 includes a battery with a capacity large enough to realize each function, an operation circuit having a calculation performance sufficient for image processing, a wireless communication device, and the like.
[0021]
Fig. 3B is a perspective view of the image-capturing-and-display unit 100 as seen from a direction different from that of Fig. 3A.
[0022]
As illustrated in Fig. 3B, the image-capturing-and-display unit 100 includes a display unit 110, the rear cover 120, and a first coupling portion 130. The first coupling portion 130 includes a first rail 131, a first support surface 132, and a first to-be-hooked portion 133.
[0023]
Similar to the front cover 140, the rear cover 120 is formed of a transparent or translucent member or a member having a hole. The user can observe a display of the display unit 110 through the rear cover 120. The display unit 110 is equipped with a projection optical system, a catoptric system, and the like as well as a display device, which is a display screen for displaying an image.
[0024]
The first coupling portion 130 is used for coupling the image-capturing-and-display unit 100 and the head-mounted unit 200 or for coupling the image-capturing-and-display unit 100 and the hand-held unit 300, and a specific function of the first coupling portion 130 will be described later.
[0025]
Fig. 4A is a perspective view of the head-mounted unit 200 in the head-mounted mode A. As illustrated in Fig. 4A, the head-mounted unit 200 includes a second coupling portion 210, an outer belt 220, an inner belt 221, a rear-head supporting unit 230, and a front-head supporting unit 240.
[0026]
As described above, in the present embodiment, the image-capturing-and-display unit 100 and the head-mounted unit 200 are removable from each other. A specific operation and mechanism for coupling and separating the image-capturing-and-display unit 100 and the head-mounted unit 200 to and from each other according to the present embodiment will be described below with reference to Figs. 4A to 4C.
[0027]
The second coupling portion 210 includes a second rail 211, a second support surface 212, a second lever 213, and a second hook 214. First, a user moves the image-capturing-and-display unit 100 to a position above the head-mounted unit 200 in such a manner that the first rail 131 is positioned above the second rail 211. Next, the user lowers the image-capturing-and-display unit 100 while pressing the first rail 131 against the second coupling portion 210. As a result, the first rail 131 and the second rail 211 engage each other. The second hook 214 is an elastic member or is supported so as to be capable of elastically deforming as a result of receiving a force from another elastic member. When the user lowers the image-capturing-and-display unit 100 to a further extent in a state where the first rail 131 and the second rail 211 engage each other, the second hook 214 is pushed away by the first coupling portion 130 toward the side on which the front-head supporting unit 240 is disposed. When the user lowers the image-capturing-and-display unit 100 to a further extent in a state where the second hook 214 has been pushed away, the first support surface 132 and the second support surface 212 are brought into contact with each other. At that moment, the second hook 214, which has been pushed away, is moved into a space above the first to-be-hooked portion 133 by a restoration force. Fig. 4B is a sectional side view illustrating the positions of the first support surface 132, the second support surface 212, the second hook 214, and the first to-be-hooked portion 133 in the above state. The second hook 214 and the first to-be-hooked portion 133 each have a portion inclined in a direction in which the second hook 214 and the first to-be-hooked portion 133 engage each other. In the case of trying to remove the image-capturing-and-display unit 100 from the head-mounted unit 200, the image-capturing-and-display unit 100 will not be removed from the head-mounted unit 200 because of the engagement of the first rail 131 and the second rail 211 and the engagement of the second hook 214 and the first to-be-hooked portion 133 (latch mechanism). The image-capturing-and-display unit 100 and the head-mounted unit 200 can be coupled to each other by performing the above operation.
[0028]
Next, when separating the image-capturing-and-display unit 100 and the head-mounted unit 200 from each other, the user uses the second lever 213. When the user moves the second lever 213 in i direction in Fig. 4B, the second hook 214 moves out of the space above the first to-be-hooked portion 133. In this state, when the user moves the image-capturing-and-display unit 100 to a position above the head-mounted unit 200, the engagement of the second hook 214 and the first to-be-hooked portion 133 is released. Accordingly, the image-capturing-and-display unit 100 is moved upward while being guided by the first rail 131 and the second rail 211. If the user keeps moving the image-capturing-and-display unit 100 upward, the first rail 131 and the second rail 211 will separate from each other. The image-capturing-and-display unit 100 and the head-mounted unit 200 can be separated from each other by performing the above operation.
[0029]
Operations to be performed by a user for wearing and removing the head-mounted unit 200 on and from the user's head will be described below.
[0030]
A user puts their head into a space enclosed by the second coupling portion 210, the outer belt 220, the inner belt 221, and the rear-head supporting unit 230. After the user's head has been brought into contact with the front-head supporting unit 240, the user operates the outer belt 220 and the inner belt 221, each of which serves as an adjusting unit. A portion of the inner belt 221 has been received in a space of the outer belt 220. When a force is applied to finger hooks 222a and 222b, the force causing the finger hooks 222a and 222b to come closer to each other, the inner belt 221 is inserted further into the space of the outer belt 220. Here, the outer belt 220 includes a retaining mechanism 223. For example, the retaining mechanism 223 may have a configuration in which a hook is hooked into a groove or a hole formed in the inner belt 221. Owing to the retaining mechanism 223, the inner belt 221 will not move in a direction in which the inner belt 221 comes off from the outer belt 220. Even if a force is applied to the finger hooks 222a and 222b, the force causing the finger hooks 222a and 222b to move away from each other, the inner belt 221 will not move in the direction in which the inner belt 221 comes off from the outer belt 220. Owing to the retaining mechanism 223, the tightening force of the head-mounted unit 200 will not be unexpectedly loosened during the period when the head-mounted unit 200 is worn on a user's head, and the head-mounted unit 200 is securely positioned. A user can wear the head-mounted unit 200 on their head by performing the above operation.
[0031]
On the other hand, the retaining function of the retaining mechanism 223 can be disabled by performing a predetermined operation. Once the retaining function of the retaining mechanism 223 has been disabled by performing the predetermined operation, the inner belt 221 is caused by a reaction force of the tightening force to separate from the outer belt 220. As a result, the tightening force of the head-mounted units 200 is reduced. The user can remove their head from the space enclosed by the second coupling portion 210, the outer belt 220, the inner belt 221, and the rear-head supporting unit 230. The user can remove the head-mounted unit 200 from the user's head by performing the above operation.
[0032]
Fig. 4C is a perspective view of the head-mounted unit 200 in the head-mounted mode A as seen from a direction different from that of Fig. 4A. The second coupling portion 210, the outer belt 220, the rear-head supporting unit 230, and the front-head supporting unit 240 are each provided with second elastic members 250, and the second elastic members 250 are disposed on the side on which the second elastic members 250 are brought into contact with a user's head. The elasticity of each of the second elastic members 250 reduces pressure concentration during the period when the head-mounted unit 200 is worn on a user's head, and the user feels more comfortable wearing the head-mounted unit 200.
[0033]
Fig. 5A is a perspective view of the hand-held unit 300 in the hand-held mode B. The hand-held unit 300 includes a third coupling portion 310 and a holding portion 320. The third coupling portion 310 includes a third rail 311, a third support surface 312, a third lever 313, and a third hook 314. An operation for coupling and separating the image-capturing-and-display unit 100 and the hand-held unit 300 to and from each other is substantially the same as the operation for coupling and separating the image-capturing-and-display unit 100 and the head-mounted unit 200 to and from each other.
[0034]
Fig. 5B is a perspective view of the hand-held unit 300 in the hand-holding mode B as seen from a direction different from that of Fig. 5A. The third coupling portion 310 is provided with a third elastic member 330 that is disposed on the side on which the third elastic member 330 is brought into contact with a user's head. A user presses their forehead and the peripheral portion against the third elastic member 330 when the user looks into the display unit 110, which is built into the image-capturing-and-display unit 100. The elasticity of each of the third elastic member 330 reduces pressure concentration on the user's forehead. If the user holds the holding portion 320 with their hands or their hand and supports the third elastic member 330 with their forehead simultaneously, the position of the image-capturing-and-display unit 100 with respect to the user's head is less likely to be displaced.
[0035]
A mechanism that prevents an image-capturing-and-display unit and a head-mounted unit from separating from each other during the period when the head-mounted device is worn on a user's head will now be described with reference to Figs. 6A and 6B. A method of coupling and separating the image-capturing-and-display unit 100 and a head-mounted unit 201 to and from each other is substantially the same as the method of coupling and separating the image-capturing-and-display unit 100 and the head-mounted unit 200 to and from each other.
[0036]
Fig. 6A is a sectional side view of the head-mounted unit 201 during the period when the head-mounted unit 201 is worn on a user's head. As illustrated in Fig. 6A, the head-mounted unit 201 includes the second coupling portion 210, the outer belt 220, and the front-head supporting unit 240. The second coupling portion 210 includes the second rail 211, the second support surface 212, the second lever 213, and the second hook 214. The front-head supporting unit 240 includes a rotary shaft 241. The rotary shaft 241 may hold the front-head supporting unit 240 at any angle and may apply a force in a direction opposite to ii direction in Fig. 6A to the front-head supporting unit 240. When a force whose magnitude is equal to or greater than a predetermined level is applied from the user's head to the front-head supporting unit 240, the front-head supporting unit 240 is pushed away so as to move in the ii direction in Fig. 6A. The term "during the period when the head-mounted unit 201 is worn on the user's head" refers to a state where the front-head supporting unit 240 is being pushed away in the ii direction in Fig. 6A by the user's head. A gap between the second lever 213 and the front-head supporting unit 240 in the above state will hereinafter be referred to as a head-mounted-state gap g1.
[0037]
When the user presses the second lever 213 in i direction in Fig. 6A in order to separate the image-capturing-and-display unit 100 from the head-mounted unit 201, the head-mounted-state gap g1 becomes narrower. However, even if the head-mounted-state gap g1 is narrowed so as to have a minimum size, the second hook 214 will not move out of the space above the first to-be-hooked portion 133. Even if there are variations in the sizes and shapes of heads of users within a range that may be normally assumed, the second hook 214 will not move out of the space above the first to-be-hooked portion 133. That is to say, the image-capturing-and-display unit 100 and the head-mounted unit 201 can be prevented from separating from each other by reducing the likelihood that the coupling by the above-described latch mechanism will be released during the period when the head-mounted device is worn on a user's head.
[0038]
The front-head supporting unit 240 that is pushed away by a user's head during the period when the front-head supporting unit 240 is worn on the user's head can be caused by an external force applied by the user to move in the direction opposite to the ii direction in Fig. 6A when the front-head supporting unit 240 is not worn on the user's head. Fig. 6B is a sectional side view of the head-mounted unit 201 after the front-head supporting unit 240 has been moved. A gap between the second lever 213 and the front-head supporting unit 240 in the above state will hereinafter be referred to as a non-head-mounted-state gap g2. In this state, the head-mounted unit 201 will not be worn on the user's head as long as the size and shape of the user's head is within a range that may be normally assumed. In addition, a relationship of head-mounted-state gap g1>non-head-mounted-state gap g2 is satisfied.
[0039]
When the user presses the second lever 213 in iii direction in Fig. 6B in order to separate the image-capturing-and-display unit 100 from the head-mounted unit 201, the non-head-mounted-state gap g2 becomes narrower. When the non-head-mounted-state gap g2 has been narrowed so as to have a minimum size, the second hook 214 moves out of the space above the first to-be-hooked portion 133. In other words, the image-capturing-and-display unit 100 and the head-mounted unit 201 can be separated from each other when the head-mounted device is not worn on a user's head.
[0040]
Regarding the head-mounted unit 201, the image-capturing-and-display unit 100 and the head-mounted unit 201 cannot be separated from each other during the period when the head-mounted device is worn on a user's head, and the image-capturing-and-display unit 100 and the head-mounted unit 201 can be separated from each other when the head-mounted device is not worn on a user's head. Thus, the head-mounted unit 201 can prevent the image-capturing-and-display unit 100 and the head-mounted unit 201 from separating from each other against a user's intention during the period when the head-mounted device is worn on the user's head.
[0041]
Electric contact points of an image-capturing-and-display unit 102 and electric contact points of a head-mounted unit 202 will now be described with reference to Figs. 7A and 7B. A method of coupling and separating the image-capturing-and-display unit 102 and the head-mounted unit 202 to and from each other is substantially the same as the method of coupling and separating the image-capturing-and-display unit 100 and the head-mounted unit 200 to and from each other.
[0042]
Fig. 7A is a perspective view of the image-capturing-and-display unit 102. The image-capturing-and-display unit 102 includes the first coupling portion 130, and the first coupling portion 130 includes first electric contact points 134.
[0043]
Fig. 7B is a perspective view of the head-mounted unit 202. The head-mounted unit 202 includes the second coupling portion 210, and the second coupling portion 210 includes second electric contact points 215.

When the image-capturing-and-display unit 102 and the head-mounted unit 202 are coupled to each other via the first coupling portion 130 and the second coupling portion 210, the first electric contact points 134 and the second electric contact points 215 are brought into contact with each other. By the contact between the first electric contact points 134 and the second electric contact points 215, the image-capturing-and-display unit 102 and the head-mounted unit 202 can supply power to each other and can perform communication with each other. For example, a battery and the like that drive the image-capturing-and-display unit 102 can be installed in the head-mounted unit 202. Alternatively, a switch and the like that operate the image-capturing-and-display unit 102 may be installed in the head-mounted unit 202. In the case where the hand-held unit 300 includes electric contact points, functions that are substantially the same as those described above can be realized.
