Wireless Gyro-mouse for Text Input on a Virtual Keyboard

In this paper, we propose a gyroscopic pointing device that allows a user to type text by using a specialized virtual keyboard. We compare different typing methods that use the dwell time of the pointer as a character selection method. The proposed solution can be used in different applications, such as: computer gaming, virtual reality, remote control and to facilitate communication with people affected by certain disabilities and can easily accommodate more types of users. The performances of different methods have been analyzed by using the speed of typing measured in words per minute, the task success rate, as well as the feedback from the user regarding comfort and perceived ease-of-use.
