This Small Business Innovation Research (SBIR) Phase II project aims to further develop the Tapping Finger Identification (TFI) technology investigated in Phase I. As mobile devices become more powerful and ubiquitous, text entry remains a major bottleneck to the wider adoption of mobile computing. To address this urgent need in lack of an acceptable solution, this TFI technology enables high-speed input in mobile devices and gaming applications using conventional typing techniques and keyboard layouts. In addition to demonstrating the feasibility of TFI during Phase I, the project will develop an IP strategy and a set of tools essential to future research and development. To date, one prototype has been implemented and a license agreement to commercialize some portion of the TFI technology was reached with an external partner. Completion of the Phase II research in two years will pave the way for commercialization of this innovative technology as we transition toward mobile computing. The technology developed could potentially impact a broad range of application areas, including mobile computing, gaming, military, and mobile security.
