Design decisions for a voice navigation system

Human factors research is utilized to design alternatives for the interface components of voice navigation applications. Design objectives are discussed, & it is noted that the voice navigation application considered here employs a multimodal approach to interfacing. Participants in study 1 (N = 14) were classified according to speech-directed application experience & were required to evaluate the appropriateness of four groups of icons, eg, microphone inactivity, to be used in a speech recognition toolbar. Despite low-knowledge user preferences, experienced users' perceptions of appropriateness received greater importance in the selection of toolbar icons. Study 2 directed participants (N = 8), all experienced users of voice recognition applications, to search for appropriate commands to complete certain tasks; an alternative means of window organization was designed to assess the application & was preferred by the participants. The findings will be integrated into future window organization designs. 5 Tables, 4 Figures, 10 References. Adapted from the source document
