CLAIMS

1. A sports training aid comprising

a sensor unit,

the sensor unit being configured to be attachable to a user’s body or a user’s sports implement, and wherein the sensor unit (110) is provided with:

- a motion sensor module;

- a feedback stimulator or means for wirelessly communicating with a feedback stimulator;

- a processor;

wherein the sports training aid is configured to provide real time feedback related to a motion fault of a studied sports motion performed by the user, and

i) wherein the sensor unit is intended to be attached to a user’s body or a user’s sports implement at a representative location, the representative location being bound to travel a path representative of the studied sports motion, and

ii) wherein the motion sensor module of the sensor unit comprises acceleration sensors and gyro sensors, and

iii) wherein the processor of the sensor unit is configured to determine, with the aid of data from the motion sensor module, a still position corresponding to an event wherein the sensor unit (110) is determined to be still, and

iv) wherein the processor is configured to keep track of the movements of the sensor module of the sensor unit relative to the still position, and

v) wherein the processor is configured to activate, in real time, the feedback stimulator upon real time detection of a sports motion fault of the studied sports motion of the user as represented by the motion path of the motion sensor module of the sensor unit.

2. The sports training aid of claim 1 wherein the processor is configured to determine the still position using a method including the following steps:

- calculating repeatedly an acceleration vector based on data from the accelerometer sensors;

- determining that the absolute value of the acceleration vector stays below a predetermined threshold value for a predetermined amount of time;

- determining that the accelerometer vector holds a steady absolute value equal or close to earth gravity acceleration for the predetermined amount of time;

3. The sports training aid of claim 1 or 2 wherein the processor is configured to determine the still position using a method including the following steps:

- determining that gyro sensor’s readings are confined within certain predefined limit values.

4. The sports training aid of claim 2 and 3 wherein the predetermined amount of time preferably is in the interval of 0.5 to 2.5 seconds, and even more preferred around 1 ,9 seconds.

5. The sports training aid of claim 2 wherein the determining of a steady absolute value includes the following step(s):

- checking that variation in accelerometer vector absolute value is within a predetermined interval preferably within +/- a percentage from earth gravity acceleration.

6. The sports training aid of claim 2 wherein the processor is configured to discard gyro sensor data when determining the still position.

7. The sports training aid of any of the preceding claims wherein the user is an animal.
