Driving Conditions

This research investigated the effects of an adaptive cruise control (ACC) system, and cell phone use in driving, on a direct objective measure of situation awareness (SA). Subjects drove a virtual car in a medium-fidelity driving simulation and performed a following task. Half of the subjects were required to respond to cell phone calls and all subjects completed trials with and without use of the ACC system. SA was measured using a simulation freeze technique and SA queries on the driving situation. Results indicated use of the ACC system to improve driving task SA under normal driving conditions, and cell phone conversations degraded SA. Results also revealed the ACC system to improve safe driving headway distance. Although the deviations in headway distance from an optimum were greater during cell phone conversations, this did not prove to be significant in terms of performance under normal driving conditions.

Development Of Language

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.
