This paper describes a small pilot study and two formal experiments that investigate the usability of sonically-enhanced buttons of different sizes. The underlying hypothesis being that presenting information about the buttons in sound would increase their usability and allow their size to be reduced. An experimental interface was created that ran on a 3Com Palm III mobile computer and used a simple calculator-style interface to enter data. The buttons of the calculator were changed in size between 4x4, 8x8 and 16x16 pixels and used a range of different types of sound from basic to complex. Results showed that sounds significantly improved usability for both standard and small button sizes - more data could be entered with sonically-enhanced buttons and subjective workload reduced. More sophisticated sounds that presented more information about the state of the buttons were shown to be more effective than the standard Palm III sounds. The results showed that if sound was added to buttons then they could be reduced in size from 16x16 to 8x8 pixels without much loss in quantitative performance. This reduction in size, however, caused a significant increase in subjective workload. Results also showed that when a mobile device was used in a more realistic situation (whilst walking outside) usability was significantly reduced (with increased workload and less data entered) than when used in a usability laboratory. These studies show that sound can be beneficial for usability and that care must be taken to do testing in realistic environments to get a good measure of mobile device usability.Wed Apr 23 22:05:04 CEST 2008Signal ProcessingMar3491--503A virtual stereo approach to stereophonic acoustic echo cancellation812001signal processing Audio Wed Apr 23 22:05:04 CEST 2008Signal ProcessingJan1163--176Perceptual audio modeling with exponentially damped sinusoids852005Perceptual modeling audio Wed Apr 23 22:05:04 CEST 2008Signal ProcessingAug81848--1858Audio source separation with a signal-adaptive local cosine transform872007source Audio separation Wed Apr 23 22:05:04 CEST 2008Signal ProcessingMar3519--531A new algorithm for translating psycho-acoustic information to the wavelet domain812001Audio coding Tue Mar 18 16:20:10 CET 2008Proceedings of ISMIR 2004Audio Issues in MIR Evaluation2004Evaluation bitrate perceptual_encoding audio Tue Mar 11 20:43:44 CET 2008New York, NY, USAComputer Music1985music synthesis computer audio Thu Nov 08 22:59:40 CET 2007New York, NY, USAIUI '07: Proceedings of the 12th international conference on Intelligent user interfaces302--304Auditory perceptible landmarks in mobile navigation20072007 mapping audio navigation iui Normally, mobile pedestrian navigation systems use visually perceptible landmarks to guide their users through the environment. In this article we introduce concepts for the use of auditory perceptible landmarks in route descriptions. Such auditory perceptible landmarks complement their visual counterparts and also stand to be beneficial for certain groups like the visually impaired and the elderly.Mon Aug 27 13:10:47 CEST 2007Communications of the Association of Computing Machinery01128-45Media Spaces: Bringing people together in a video, audio, and computing environment361993spaces video sos-buch bringing Bringing audio Spaces Media computing Wed Jul 04 00:01:34 CEST 2007Latent Semantic Mapping2006Processing Synthesis Lectures Audio on and LSI Speech S.
