The response to the Mobile HCI symposium has been positive in terms of submissions and participation. The contributions, especially the long papers, were selected carefully by the International Program Committee. The result is a set of interesting and stimulating papers that address such important issues as location awareness, design criteria for PDAs, context-dependent systems, innovative case studies, usability evaluation in small devices, and novel interfaces for mobile devices. Recent years have seen the introduction of many types of computers and devices (e.g., cellphones, PDAs, etc.) and the availability of this wide range of devices has become a fundamental challenge for designers of interactive software systems. Users wish to be able to seamlessly access information and services regardless of the device they are using, even when the system or the environment changes dynamically. To this end, computer-based applications need to run on a wide spectrum of devices. The interest shown in the symposium has truly been worldwide: with authors from 16 countries on three continents, and a good balance of contributions from academia and industry. The final program of the symposium included two technical invited speakers (Brad Myers from Carnegie Mellon University and Luca Passani from Openwave), 18 full papers and 32 short papers, as well as a session with a representative of the European Commission to present and discuss their future programs in this area, and a number of interactive demos that allow participants to have direct experience of innovative results.
