This paper describes a Kinect-based virtual keyboard using finger gestures. Existing systems usually involve expensive range sensors or custom-built hardware equipment. Furthermore, range sensor-based keyboards that are used to detect taps on imaginary keys suffer from shortcomings that were originally reported for touch-screen keyboards: There is a lack of tactile feedback, which has a negative effect on typing performance. The proposed Gestairboard extends the Gestyboard touchscreen keyboard concept that was suggested in 2011 to overcome exactly that problem, thus adapting it for devices without a touchscreen. It also uses inexpensive off-the-shelf hardware and to the best of our knowledge is the first implementation of a touch typing keyboard using Kinect. The prototype was compared to the Gestyboard and to a physical keyboard and evaluated in terms of performance, reliability, learnability and user acceptance.
