This paper presents a preliminary evaluation of the perceived entertainment value and ease of use of three eyes-free interfaces for point-and-click games. Interface 1 (I1) uses a web-like cyclical navigation system to change the focused interactive element. Interface 2 (I2) uses a sonar to help the user locate interactive elements with the mouse. Interface 3 (I3) interprets natural language commands typed in by the player. Results suggest that I2 adds more entertainment value and is appropriate for experienced players. Players find I1 is the easiest to use while I3 seems more adequate for users with little gaming experience.
