With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
3. Unity of invention is lacking
This International Searching Authority found multiple inventions in this international application, as follows:
1. claims: 1-12
A head-mounted display, having a housing, a headband and an headband adjustment mechanism responsive to a control signal generated by a feedback component, and an eye tracking system that is operable to measure motion of the housing relative to the eyes of the user, wherein the control signal is based in part on the motion of the housing relative to the eyes of the user (i.e. the combination of features of claims 1 and 10).
2. claims: 13-15
A head-mounted display, having a housing, a headband and an headband adjustment mechanism responsive to a control signal generated by a feedback component, wherein the adjustment mechanism includes a variable volume structure that changes fit of the headband relative to the head of the user by volumetric expansion or volumetric contraction (i.e. the combination of features of independent claim 13).
3. claims: 16-18
A method for adjusting a head-mounted display, comprising:loosening a headband upon detecting user contact with a first location and a second location on the housing; andtightening the headband upon detecting cessation of user contact with the first location or the second location on the housing (i.e. the combination of features of independent claim 16).
4. claims: 19-23
A head-mounted display, having a housing, a headband and a support to extend over a head of the user, having a first portion that is connected to the housing, a second portion that is adjustably connected to the first portion, and a third portion that is adjustably connected to the second portion, wherein the third portion defines a free end for the support assembly that is free from connection to the housing (i.e. the combination of features of independent claim 19).
1.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
2.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
3.
As only some of the required additional search fees were timely paid by the applicant, this international search report covers only those claims for which fees were paid, specifically claims Nos.:
4.
No required additional search fees were timely paid by the applicant. Consequently, this international search report is restricted to the invention first mentioned in the claims; it is covered by claims Nos.: 1-12
