Exploiting Location-Based Composite Devices to Support and Facilitate Situated Ubiquitous Computing

Ubiquitous computer aided design: A broken promise or a Sleeping Beauty?

“…According to their interpretation, traditional business computing is characterized by a low LoE and a low LoM, mobile computing by a high LoM and a low LoE, pervasive computing by a low LoM and a high LoE, and ubiquitous computing is characterized by a high LoE and a high LoM [13]. Independence from location and access modalities of computing has lent itself to the movement of computer technologies from the forefront of our daily routine activities to the background [14]. Observing that people continue to view mobile computing devices as mini-desktops, applications as programs that run on these devices, and the environment as a virtual space that a user enters to perform a task and leaves when the task is finished, Banavar et al proposed to adopt three precepts of pervasive computing: (i) a device is a portal into an application/data space, not a repository of custom software managed by the user, (ii) an application is a means by which a user performs a task, not a piece of software that is written to exploit a device's capabilities, and (iii) the computing environment is the user's information-enhanced physical surroundings, not a virtual space that exists to store and run software [15].…”

“…It assumes possibility of making network connections in multiple forms while changing spatial position, and thereby of searching, visualization, data input, and communication [14]. This is contrasted by the idea of nomadic computing, which is also based on the use of 'portable' devices, but no mobility while connected [59].…”

A framework for policy based coordinated adaptation in mobile systems

“…A new version of the Teleporting system developed at AT&T Laboratories uses a new location tracking system called the Bat3, which is based on both ultrasonic and radio signals [25]. Composite Device Computing Environment (CDCE) [26] is also working on a project, aimed to supplement resource-poor PDA with surrounding computing resources such as PCs, workstations, TVs, and telephones.…”
