Description
Summary:A series of user trials carried out to assess the performance & usability of the Multimodal Multimedia Service Kiosk (MASK) prototype is reported on. The aim of the ESPRIT MASK project was to pave the way for advanced public-service applications with user interfaces employing multimodal, multimedia input & output. After analyzing the technological requirements in the context of users performing travel inquiry tasks, the prototype kiosk was developed in close collaboration with French Railways & the Ergonomics group at the University College of London. The time to complete a transaction is reduced by about 30% with the MASK kiosk as compared to the standard kiosk, & the transaction success rate is 85% for novices & 94% for those familiar with the system. In addition to meeting or exceeding the performance goals set for the project in terms of success rate, transaction time, & user satisfaction, the MASK kiosk was judged to be user-friendly & simple to use. 3 Tables, 4 Figures, 16 References.
