Abstract
This paper presents an evaluation of Tap Strap 2, a one-handed wearable keyboard that uses tap combinations to type characters. The purpose of the Tap Strap 2 is to give the user a portable keyboard that is easier to use for mobile devices than the on-screen QWERTY keyboards included on those devices. The user taps different combinations of fingers on a surface to enter different characters and perform a variety of commands. By using the embedded sensors in each ring, the Tap Strap 2 can recognize which fingers are tapping at any given time. Tap Strap 2 also has a mouse mode that can be switched to from keyboard mode, allowing the user to browse websites on a mobile device as they would on a computer. The third mode that Tap Strap has is a gesture mode that can be used for mobile devices as well as in virtual reality settings. This article details what Tap Strap 2 is capable of and describes the hardware. It also provides an evaluation of the device’s usability and tests an auto-correct algorithm meant to reduce the probability of spelling errors when using the Tap Strap 2.
