Abstract |
|
|
| Designing a slim and wide multi touch tabletop interface is a key element in interactions with multiple users. We propose
a slim and large tabletop interface based on a wide LED display. The proposed tabletop interface uses two cameras with two
reflection mirrors. Its thickness is less than 8 inches and its screen size is 47 inches. In order to recognize multi-touch inputs and
dragging operations more effectively and efficiently, the proposed system adopts a hybrid recognition approach, which combines FTIR
(Frustrated Total Internal Reflection) and LLP (Laser Light Plane). The proposed tabletop interface also provides a conflict resolution
algorithm where multiple cameras are redundantly used to recognize user inputs. The proposed tabletop interface has deployed various
different applications such as e-Menu for restaurants, e-Catalogue for digital fashion and computer games. The performance of the
proposed system was evaluated. It showed real-time recognition of multi-touch user inputs with reliable overlapped resolutions1. |
