Abstract We introduce Z-touch, a multi-touch table that can detect spatial hand gestures near the tabletop surface.  ...  (a): Tabletop of Z-touch. Multilayered line laser modules are placed at the edge of the tabletop panel. (b): Captured depth map of the hand near the top panel of Z-touch shown in (a).  ...  System Design Conclusion We introduced Z-touch, that combines multi-touch and 3D hand gesture detection near the surface of a tabletop, using multilayered IR line lasers synchronized with the shutter  ...

In order to detect touches on the multi-touch surface, the multi-touch system must be able to capture the infrared hotspots where a user touches. An infrared camera is used for this purpose.  ...  Z-touch uses multiple laser light planes to divide the space above the surface. The system is able to detect how close a finger or object is to the surface.  ...  colophon This thesis was typeset with the pdflatex L A T E X 2 ε interpreter using Hermann Zapf's Palatino type face for text and math and Euler for chapter numbers.  ...

We present a novel photo touch sensing architecture, HACHIStack.  ...  This work quantitatively examines these capabilities through two laboratory experiments, and confirms that the capabilities of HACHIStack are sufficient for multimodal interaction, in particular, touch-based  ...  The current system cannot detect multi-touch. A possible solution for this is to stack the optical multi-touch detection sensor [34] vertically.  ...

Tangible Educational Game for Pre-school Children

Yuchen Wang
Over the last decade, interest and excitement surrounding interactive surfaces and multi-touch tabletops has increased substantially.  ...  This thesis presents a system that not only enables users to interact on the tabletop surface, but also make use of the space above it and provide useful feedback.  ...  [4] develop a multi-touch tabletop system, the AIR Touch, which combines existing multi-touch technologies with a suite of new rehabilitation-centric applications.  ...

Finger orientation as an additional input dimension for touchscreens [article]

Sven Mayer, Universität Stuttgart, Universität Stuttgart
The keyboard is still one of the two main input devices for desktop computers which is accompanied most of the time by a mouse or trackpad.  ...  Second, we present design guidelines for a comfortable use of finger orientation.  ...  [188] enlarged the set of use cases to the smartwatch domain.
