Symbolic input, including text and numeric input, can be an important user task in applications of virtual environments (VEs). However, very little research has been performed to support this task in immersive VEs. This paper presents the results of an empirical evaluation of four text input techniques for immersive VEs. The techniques include the Pinch Keyboard (a typing emulation technique using pinch gloves), a one-hand chord keyboard, a soft keyboard using a pen & tablet, and speech. The experiment measured both task performance and usability characteristics of the four techniques. Results indicate that the speech technique is the fastest, while the pen & tablet keyboard produces the fewest errors. However, no single technique exhibited high levels of performance, usability and user satisfaction.

Virtual Reality Exposure

This study is an examination of the effect of computer-generated virtual reality graded exposure on the physiological and psychological responses of performing musicians. Eight university saxophone majors, five men and three women, participated in twelve 15- to 20-minute weekly practice sessions during which they were immersed in one of four different virtual environments designed to elicit various anxiety levels. Baseline heart rates and subjective measurements were taken prior to immersion and continued throughout the exposure period. In addition, heart rate and subjective measurements were recorded for three live performances given by each subject before beginning the virtual reality exposure and after completion of the sixth and the twelfth exposure sessions. Findings indicated that the virtual environments did elicit a sense of presence and may have provided the means for desensitization. Heart-rate readings and psychological indications of anxiety did not always correspond.
