Abstract

A device configured to acquire tactile information, including a transparent tactile matrix sensor; a display device; a measurement unit configured to simultaneously measure a first position of a first finger and a second position of a second finger that are placed on the transparent tactile matrix sensor; a graphical processing unit configured to generate a first and a second cursor that are associated with the first and second position, respectively; and a processor configured to execute an application that associates the first and second cursors with a graphical object that is displayed on the display device, to interact with the graphical object.

Claims

1. A device configured to acquire tactile information, comprising.

a transparent tactile matrix sensor;

a display device;

a measurement unit configured to simultaneously measure a first position of a first finger and a second position of a second finger that are placed on the transparent tactile matrix sensor;

a graphical processing unit configured to generate a first and a second cursor that are associated with the first and second position, respectively; and

a processor configured to execute an application that associates the first and second cursors with a graphical object that is displayed on the display device, to interact with the graphical object.

2. The device according to claim 1, wherein the graphical processing unit is configured to destroy the first and the second cursors, respectively, when the measurement unit detects that the first finger and the second finger, respectively, have been removed from the transparent tactile matrix sensor.

3. The device according to claim 1, wherein the modification of a movement of the graphical object by the processor follows an interaction rule as a function of the first and the second cursor, and the interaction rule is based on a physical model.

4. The device according to claim 3, wherein the physical model follows a spring-like behavior.

5. The device according to claim 3, wherein the physical model is based on a vibration of a string.

6. The device according to claim 3, wherein the physical model is configured to stimulate collisions of the graphical object.

7. The device according to claim 3, wherein the physical model is configured to simulate effects of gravity.

8. The device according to claim 3, wherein the physical model is configured to simulate effects of an electromagnetic field on the graphical object.

9. The device according to claim 3, wherein the graphical object includes a plurality of movable objects that are located inside a rectangular area, and the physical model is configured such that the first and the second cursors are moved by a movement of the first and second fingers, and will apply a inertia movement to the plurality of movable objects once at least one of the first or second finger is retracted from the transparent tactile matrix sensor.

10. The device according to claim 9, where physical model is configured such that the moving of the objects will rebound from a border of the rectangular area and will rebound if the objects collide with each other.
