We propose StickyTouch, a novel tactile display that represents an adhesive information. This adhesive surface is capable of manipulating the degree of adhesion, enabling new kinds of interactions such as attaching and detaching the user’s fingers. Adhesion control is achieved with a temperature sensitive adhesive sheet whose temperature is locally controlled by Peltier devices arranged in a grid. In this paper, we describe the details of principle and system design of StickyTouch, and discuss the implementation of a proof-of-concept prototype with 64 Peltier devices with an adhesive size of 150×150 mm. We conduct several experiments on adhesion perception when touching and swiping on the display surface to evaluate the performance of StickyTouch. Finally, we discuss the applications for touch and swipe and our future prospects.

We propose CoiLED Display, a stripe-shaped flexible display that can be wound around various objects. CoiLED Display is composed of a large number of chip LEDs arranged in a row, and the object wound by CoiLED can display image information. To recognize the configuration of display units wound around an object, the system conducts calibration by capturing the lighting of the LEDs with a camera and obtaining their relative positions with image processing. We evaluated the performance of the prototyped CoiLED Display from four aspects: processing time, refresh rate, power consumption, and physical flexibility. We then conducted a design study to evaluate the usability of the CoiLED Display and explored its application design space. The results suggest that the participants generally accepted our system, including the calibration process. In addition, the participants came up with a wide range of application area (e.g. wearable displays, public displays).
