Abstract
UVMODE 2.0 is an internet-based mixed reality system for the design process of mobile information device development, supporting cooperative works between customers and product developers. The UVMODE 1.0 had been developed for usability engineers, but the UVMODE 2.0 was expanded for CSCW(Computer Supported Cooperative Work) among product planners, developers, designers and customers. The system includes photorealistic rendering and embedded software simulation modules in order to provide users with high-level satisfaction in sensory modality, such as visual impressions, sound effects, and haptic feedback with the presented virtual products. With the external form generation module which uses 3D printing machine, users can grab the product prototype in their hands and feel the physical shape of it. The system also supports to perform usability tests of ergonomic issues using a sensory-unified platform which combines an augmented reality display module that overlays a realistic image on the physical mock-up, with a sensing glove module that measures physical loads on each part of the user's hand. Finally, in order to realize the collaborative design scenario between customers and developers, the system provides an internetbased design cooperation module with which users can easily create a new prototype design by a semi-automatic process using a product part database. The design cooperation module also has a user preference collection and prediction engine that analyzes the relationship between users' affective satisfaction level and design parameters. In this paper, we present the second version of UVMODE system which can improve the efficiency of the product design and usability evaluation process. While it was designed as an integrated system, each module could be also applied separately in the product design process for specific purposes. Our research will be especially useful in practical situations where industries must quickly accommodate customers' needs in their product design process. Cooperative design and evaluation of mobile devices will help industries to improve the quality and efficiency of their products in the design phase, in advance of the manufacturing stage.
