Reflective haptics: enhancing stylus-based interactions on touch screens

In this paper, we introduce the prototype of a low cost haptically augmented stylus for pen computing on touch screens. The stylus supports human-computer interaction through a dynamic haptic feedback. This reflective feedback is generated by a magnetically operated brake system. The feedback actuator is integrated in the stylus. Therefore, the pen supports the use of multiple styli on a single touch screen. The pen provides a broad scale of feedback-especially for the display of haptic surface cues. Hence, it is predestined for stroke gestures, as they are commonly used in crossing-based pen interfaces.

Chemieraum: tangible chemistry in exhibition space

This paper describes a new interactive exhibit that should motivate young people to easily explore the field of chemistry with the help of a tabletop interface. This interface is controlled by a new input device equipped with a haptic and visual feedback.

Reflective haptics: haptic augmentation of GUIs through frictional actuation of stylus-based interactions

In this paper, we present a novel system for stylus-based GUI interactions: Simulated physics through actuated frictional properties of a touch screen stylus. We present a prototype that implements a series of principles which we propose for the design of frictionally augmented GUIs. It is discussed how such actuation could be a potential addition of value for stylus-controlled GUIs, through enabling prioritized content, allowing for inherent confirmation, and leveraging on manual dexterity.
