Abstract

We present a novel touch sensitive handheld device, called Palm Touch Panel, which provides electro-tactile feedback on the back of the device thus simulating the sensation of being able to touch the user's palm directly through the device. Users hold the mobile device, which has an electro-tactile display attached at the back. When a finger touches the visual cues on the front screen panel, such as a button or an icon, the electro-tactile display at the back transmits the unique tactile sensation associated with this behavior of the cues to the palm of the hand. As a result, we speculate that the user can manipulate visual information with less visual attention, or even potentially in an eyes-free manner. In this paper we discuss the creation of this unique mobile device that allows the palm to be used for tactile feedback, thus enhancing the touch screen experience.
