PDAs as Remote Interactive Devices Using Native Code

Abstract

In order to study the effectiveness of PDA-native applications and interactive devices in a multi-device networked environment, we developed two applications. A remote text-entry and text display application was developed first. Once the infrastructure was in place, we went on to develop a remote control application for LCD projectors. In order to accommodate low-latency operations, we interfaced Palm III devices to a Linux server using a direct serial connection. Palm-specific code was written in C++ using Metrowerks CodeWarrior for execution under PalmOS 3.0. For the server, standard gcc C++ was used on a PC running Red Hat Linux 5.2.
