Abstract

A hand-held input/control device designed and configured such that, when it is held by a user oriented with its operating surface facing away from the user, the user may view the operation of the manually operable control members deployed on that operating surface.

Claims

1. A hand-held input device, comprising:

a housing configured for convenient holding by two hands of a user, with an upper surface of the housing facing towards the user and an undersurface of the housing facing away from the user, and with the fingers of the user underlying said undersurface;

and at least one manually operable control member carried by said undersurface of the housing facing away from the user when the housing is held by the user;

said housing being constructed such as to enable the user, when holding the housing by the user'"'"'s two hands with the undersurface of the housing facing away from the user, to view the fingers of the user underlying said undersurface, and to guide them for operating the control member carried by said undersurface.

2. The device according to claim 1, wherein said housing is configured with two handgrips on its opposite sides shaped for convenient holding by the two hands of the user, with the thumbs of the user overlying said handgrips, and the fingers of the user underlying said undersurface of the housing.

3. The device according to claim 2, wherein each of said handgrips also includes at least one manually operable control member engageable by a thumb of the user.

4. The device according to claim 2, wherein the undersurface of the housing includes a plurality of said manually operable control members.

5. The device according to claim 1, wherein said housing is constructed with at least a part thereof being light-transmissive such as to enable the user, when holding the housing by the user'"'"'s two hands with the undersurface of the housing facing away from the user, to view the fingers of the user underlying said undersurface and to guide them for operating the control member carried by said undersurface.

6. The device according to claim 5, wherein said light-transmissive part of the housing is light-transparent.

7. The device according to claim 1, wherein said housing is constructed with a reflective surface located such as to enable the user, when holding the housing by the user'"'"'s two hands with the undersurface of the housing facing away from the user, to view the fingers of the user underlying said undersurface and to guide them for operating the control member carried by said undersurface.

8. A hand-held input device, comprising:

a housing configured for convenient holding by two hands of a user, with an upper surface of the housing facing towards the user and an undersurface of the housing facing away from the user, and with the fingers of the user underlying said undersurface;

and at least one manually operable control member carried by said undersurface of the housing facing away from the user when the housing is held by the user;

said housing being constructed with at least a part thereof being light-transmissive such as to enable the user, when holding the housing by the user'"'"'s two hands with the undersurface of the housing facing away from the user, to view the fingers of the user underlying said undersurface and to guide them for operating the control member by said undersurface.

9. The device according to claim 8, wherein said light-transmissive part of the housing is light-transparent.

10. The device according to claim 8, wherein said housing is configured with two handgrips on its opposite sides shaped for convenient holding by the two hands of the user, with the thumbs of the user overlying said handgrips, and the fingers of the user underlying said undersurface of the housing.

11. The device according to claim 8, wherein each of said handgrips also includes at least one manually operable control member engageable by a thumb of the user.

12. The device according to claim 8, wherein the undersurface of the housing includes a plurality of said manually operable control member each including indicia viewable by the user when holding the housing.
