A lightweight remote display management protocol for mobile devices

Mobile phone users rely on their device displays to provide both information (e.g., currently-playing song) and alerts (e.g., caller ID). Unfortunately, phone inaccessibility coupled with display or user constraints often make it difficult for users to view and respond to alerts in a timely manner. Our lightsweight remote display (LRD) concept addresses this problem by enabling phones to discover and use alternative displays nearby. The LRD management protocol (LRDMP) is specifically tuned for use with resource-constrained displays such as wrist-watches, yet designed to be extensible for use with a wide variety of display devices with diverse capabilities. In this paper, we describe the design and implementation of LRDMP, discuss our prototype deployment model and conclude with a look at related work and relevant applications of this technology.
