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 touch panel, comprising;

a transparent sensor having a plurality of sensing zones, the zones arranged in a matrix;

a scanning unit configured to detect a tactile activation of at least two of said plurality of sensing zones; and

a processing unit configured to determine whether the at least two zones are adjacent to each other in the matrix, and to calculate a location of the tactile activation on the touch panel associated with the at least two adjacent zones.

2. A touch panel, comprising:

a transparent sensor having a plurality of sensing zones, the zones arranged in a matrix;

a scanning unit configured to detect simultaneous tactile activation on the touch panel to sense at least two clusters of zones of said plurality of sensing zones; and

a processing unit configured to calculate a location for each of the at least two clusters of zones, respectively, each calculated location representing a position of one of the simultaneous tactile activation on the touch panel that forms one of the at least two clusters.
