Abstract
Embodiments of the present invention disclose a system and method of touch discrimination using a fisheye lens. According to one embodiment, touch discrimination is provided using a touch-enabled display and an imaging device equipped with a fisheye lens and housed within the display. Furthermore, image data captured using the fisheye lens of the imaging device is utilized to detect a touch on a surface of the display along with the user associated with said touch.
Claims15
A touch discrimination system comprising:
- a touch-enabled display;
- an imaging device housed within the display and having a fisheye lens;
- wherein image data captured using the fisheye lens of the imaging device is utilized to detect a touch on a surface of the display and a user associated with said touch.
A method for touch discrimination on a touch-enabled display, the method comprising:
- detecting, via at least one image sensor having a fisheye lens and housed within the display, touch input on a surface of the display from at least one operating user;
- analyzing, via a processor, image data captured using the fisheye lens of the image sensor;
- discriminating touch input from multiple users based on the image data.
A computer readable storage medium for touch discrimination having stored executable instructions, that when executed by a processor, causes the processor to:
- detect touch input on a display from at least one operating user;
- wherein the display is horizontally-arranged and includes a perimeter area;
- analyze image data received from an image sensor having a fisheye lens;
- discriminate touch input from multiple users based on the image data received from the image sensor.
