    Traxion: A Tactile Interaction Device with Virtual Force Sensation


Entry Number: 25


    Several systems have been proposed for incorporating haptic feedback into Human-Computer Interactions. There are two types of haptic feedback. In one type, which we call “force-feedback,” a real-world physical force is created. In the second type, called “tactile-display,” physical sensations, such as vibrations, are created as an additional feedback method.

    There have been a few previous attempts to create force without using mechanical support. Nakamura et al. combined two or three eccentrically weighted rotors to generate an illusory sensation of force [Nakamura and Fukui 2005]. Amemiya et al. also proposed a device that creates a perceptual attraction force [Amemiya et al. 2008]. However, these devices are based on the mechanical movement of a crank, the form factor of the device is much bigger and heavier than those of tactile displays.

    In this demonstration, we will introduce a tactile device, called “traxtion”, that creates a virtual force without requiring any mechanical links to the ground [Rekimoto 2013]. It is significantly smaller and lighter than previous virtual force devices. Our mechanism uses a human illusory sensation to create the perception of a force. The weight of the device is about 5.2 g and the size is 7.5 mm × 35.0 mm × 5.0 mm. This small form factor allows the development of several new applications using virtual force. For example, a user can be guided to a particular location by being virtually “pulled” by a device, or an input device with non-tethered force feedback would become possible.
