With the evolving functionality in TV-based information and
entertainment appliances, there is an increased need to enable users
input text through remote control devices. We present a novel text
input method, TNT, for interactive TV, multimedia home terminals or
other similar applications. Embodied in a TV remote control and guided
by a visual map on the TV screen, TNT was designed for consistent
spatial S-R compatibility and consistency of use. Five users tested TNT
in ten sessions of 45-minutes. This initial investigation showed that
users on average could type 9.3 and 17.7 correct words per minute with
TNT doing the slowest and the fastest session respectively. The study
also showed that the users found the TNT method easy to grasp and fun
to use. Subjectively the participants felt they mastered the method
rather quickly in comparison to their actual speed improvement.
