Liang, Rong-Hao, Cheng, Kai-Yin, Su, Chao-Huai, Weng, Chien-Ting, Chen, Bing-Yu and Yang, De-Nian (2012): GaussSense: attachable stylus sensing using magnetic sensor grid. In: Proceedings of the 2012 ACM Symposium on User Interface Software and Technology 2012. pp. 319-326.

This work presents GaussSense, which is a back-of-device sensing technique for enabling input on an arbitrary surface using stylus by exploiting magnetism. A 2mm-thick Hall sensor grid is developed to sense magnets that are embedded in the stylus. Our system can sense the magnetic field that is emitted from the stylus when it is within 2cm of any non-ferromagnetic surface. Attaching the sensor behind an arbitrary thin surface enables the stylus input to be recognized by analyzing the distribution of the applied magnetic field. Attaching the sensor grid to the back of a touchscreen device and incorporating magnets into the corresponding stylus enable the system 1) to distinguish touch events that are caused by a finger from those caused by the stylus, 2) to sense the tilt angle of the stylus and the pressure with which it is applied, and 3) to detect where the stylus hovers over the screen. A pilot study reveals that people were satisfied with the novel sketching experiences based on this system.

Lin, Shu-Yang, Su, Chao-Huai, Cheng, Kai-Yin, Liang, Rong-Hao, Kuo, Tzu-Hao and Chen, Bing-Yu (2011): Pub -- point upon body: exploring eyes-free interaction and methods on an arm. In: Proceedings of the 2011 ACM Symposium on User Interface Software and Technology 2011. pp. 481-488.

This paper presents a novel interaction system, PUB (Point Upon Body), to explore eyes-free interaction in a personal space by allowing users tapping on their own arms to be provided with haptic feedback from their skin. Two user studies determine how users can interact precisely with their forearms and how users behave when operating in their arm space. According to those results, normal users can divide their arm space at most into 6 points between their wrists and elbows with iterative practice. Experimental results also indicate that the divided pattern of each user is unique from that of other ones. Based on the design principles from the observations, an interaction system, PUB, is designed to demonstrate how interaction design benefits from those findings. Two scenarios, remote display control and mobile device control, are demonstrated through the UltraSonic device attached on the users' wrists to detect their tapped positions.

Cheng, Kai-Yin, Liang, Rong-Hao, Chen, Bing-Yu, Laing, Rung-Huei and Kuo, Sy-Yen (2010): iCon: utilizing everyday objects as additional, auxiliary and instant tabletop controllers. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 1155-1164.

This work describes a novel approach to utilizing everyday objects of users as additional, auxiliary, and instant tabletop controllers. Based on this approach, a prototype platform, called iCon, is developed to explore the possible design. Field studies and user studies reveal that utilizing everyday objects such as auxiliary input devices might be appropriate under a multi-task scenario. User studies further demonstrate that daily objects can generally be applied in low precision circumstances, low engagement with selected objects, and medium-to-high frequency of use. The proposed approach allows users to interact with computers while not altering their original work environments.
