Competitive Usability Analysis of Phone Interface for Television Text Entry

Abstract

As consumer electronics become more interactive, designers are increasingly looking for novel ways to control the user interfaces. With market competition and fast-track time to market constraints, devices that have a familiar use and appeal while being new in application are seen as advantageous. This evaluation looks at the usability of the familiar phone interface for text entry on televisions. How will users initially perceive the concept of phone interface? Will the current cell phone method of text entry be transparent to users? How does it compare to other text entry devices? Results indicate that the phone interface device is initially highly acceptable to users but fails dramatically in usability.
