Efficiency of Multi-tap Text Entry Method on Interactive Television

Popis výsledku v původním jazyce

The paper investigates the effect of response time and keystroke loss ratio on text entry on an Interactive Digital Television system using a remote control. Both parameters were identified based on previous empirical evidence. They are usually caused bypoor hardware, software, or the quality of buttons. We conducted an experiment with 15 participants using a Multi-tap text entry method to perform text-copy tasks under different conditions. Entry rate, error rate, and subjective rating were measured inthe experiment. The limit values, which have only minimal effect on user performance, are 200 ms response time and 2% keystroke loss ratio. However, these values still cause a significant decrease in subjective user comfort. Based on this observation wedetermined the maximum response time to 100 ms and the keystroke loss ratio to 1%.
