Abstract

A portable virtual-reality interactive system includes a computer that is interoperable with a smartphone, a flexible roll-up mat that has an electrically-activated stiffening mechanism and a projector for projecting a virtual keyboard onto the mat. The stiffening mechanism includes embedded coils surrounding a flexible electrical wire. A portion of the mat may be configured to serve as an on-demand workspace for controlling a cursor on the smartphone. A finger cap with a pressure sensor may be used to control a cursor and register mouse clicks. The finger cap may also be used to track movements of a user. A headset may be used, which contains a compartment for the smartphone so that when the headset is worn, the user can see the view screen of the smartphone.

Claims

1. A portable virtual-reality interactive system comprising:

a computer comprising a processor, non-transitory computer memory, and a video card;

a smartphone comprising a view screen, the smartphone configured for interoperability with the computer;

a flexible roll-up mat comprising a stiffening mechanism configured for electrical activation;

the stiffening mechanism comprising a plurality of embedded coils, each embedded coil in the plurality of embedded coils surrounding a flexible electrical wire; and

a projector configured to project an image of a keyboard on the flexible roll-up mat when the flexible roll-up mat is unrolled, the flexible roll-up mat configured to recognize contact with individual keyboard keys shown in the image for entering data into the smartphone.

2. The portable virtual-reality interactive system of claim 1, wherein the flexible roll-up mat further comprises a portion thereof configured to serve as an on-demand workspace for controlling a cursor on the smartphone.

3. The portable virtual-reality interactive system of claim 2, further comprising a finger cap configured for sliding on a finger of a user and further configured for use on the on-demand workspace, the finger cap comprising a pressure sensor at a distal end of the finger cap, the pressure sensor configured to register downward pressure on the pressure sensor as a mouse click.

4. The portable virtual-reality interactive system of claim 3, wherein the finger cap is configured to track movements of the user.

5. The portable virtual-reality interactive system of claim 1, wherein the interoperability of the smartphone and computer comprises an ability of the computer to project an image on the view screen that appears to extend beyond the smartphone.

6. The portable virtual-reality interactive system of claim 1, further comprising a headset configured to be worn on a user'"'"'s head and containing a compartment for the smartphone so that when the headset is worn, a user can see the view screen of the smartphone.

7. The portable virtual-reality interactive system of claim 6, wherein the compartment contained in the headset holds the smartphone in a fixed position relative to the user.

8. The portable virtual-reality interactive system of claim 1, wherein the flexible roll-up mat is further configured to recognize contact with individual keyboard keys shown in the image for input to the computer.
