Visual and touch interaction display
A sensory display for experiencing rigidity and local shape in the display is provided. Rigidity and local shape of cells in an array of cells forming the display is controlled by three independent and different control mechanisms. Cell rigidity controllers control the rigidity of the cells. A shape array controller controls the shape of the array of cells. Cell pinning controllers controls the height of the cells. A computer control interface could control the respective control functionalities of each of the controllers. The display experience could be further enhanced with audio, images or video.
1. A display for experiencing visual and touch interaction, comprising:
(a) an array of cells, wherein each of the cells has a flexible membrane filled with a granular material, a fluid or a combination thereof, and wherein each of the cells is independently connected to a cell rigidity controller to control the rigidity of the cell independently of the other cell rigidity controllers;
(b) a chamber located underneath the array of cells, wherein the chamber is connected to a shape array controller to control the overall shape of the array of cells independently of the cell rigidity controllers controlling the rigidity of the cells; and
(c) each of the cells independently connected to a cell pinning controller to control the height of the cell independently of the other cell pinning controllers, independently of the cell rigidity controller to control the rigidity of the cell, and independently of the shape array controller to control the overall shape of the array of cells.
2. The display as set forth in claim 1 , wherein each of the cell rigidity controllers comprises a mechanism to change the pneumatic pressure inside the cell, whereby a change in cell pneumatic pressure results in a change of rigidity of the cell.
3. The display as set forth in claim 1 , wherein each of the cell rigidity controllers comprises a mechanism to change the hydraulic pressure inside the cell, whereby a change in cell hydraulic pressure results in a change of rigidity of the cell.
4. The display as set forth in claim 1 , wherein each of the cell rigidity controllers comprises a mechanism to change the electrical field inside the cell, whereby a change in cell electrical field results in a change of rigidity of the cell.
5. The display as set forth in claim 1 , wherein each of the cell rigidity controllers comprises a mechanism to change the magnetic field inside the cell, whereby a change in cell magnetic field results in a change of rigidity of the cell.
6. The display as set forth in claim 1 , wherein the granular material is coffee grounds, sand, glass beads, wood or metal chips, sawdust, dirt, salt, flour, or a combination thereof.
7. The display as set forth in claim 1 , wherein the fluid is water, oil, an electrorheological fluid, a magnetorheological fluid, or a combination thereof.
8. The display as set forth in claim 1 , wherein the shape array controller comprises a mechanism to change pneumatic pressure inside the chamber, whereby a change in chamber pneumatic pressure results in a change of the overall shape of the array of cells.
9. The display as set forth in claim 1 , wherein the shape array controller comprises a mechanism to change hydraulic pressure inside the chamber, whereby a change in chamber hydraulic pressure results in a change of the overall shape of the array of cells.
10. The display as set forth in claim 1 , wherein the cell pinning controller controls the height of one or more nodes, wherein the nodes are cell boundaries or bordering points between the cells.
11. The display as set forth in claim 1 , wherein each of the cell rigidity controllers, the shape array controller, each of the cell pinning controllers comprises a computer control interface to control their respective control functionalities.
12. The display as set forth in claim 1 , wherein each of the cell rigidity controllers, the shape array controller, each of the cell pinning controllers are controlled by a computer program executable by a computer to control their respective control functionalities.
13. The display as set forth in claim 1 , wherein each of the cell rigidity controllers, the shape array controller, each of the cell pinning controllers are controlled by a computer program executable by a computer to control their respective control functionalities, and wherein the computer program is synchronized with audio, an image or a video.
14. The display as set forth in claim 1 , wherein each of the cell rigidity controllers, the shape array controller, each of the cell pinning controllers are controlled by a computer program executable by a computer to control their respective control functionalities, and wherein the computer program is synchronized with an image or a video sequence of images that are super-imposed on the display.
