April 2007 In-Vehicle Information Systems are a desired feature within modern commercial vehicles. Such systems are often built within the workstations of new vehicle models, but are also available as ‘bolt-on’ systems, available for integration within older vehicles, or those vehicles currently produced without such additional features. Performing additional secondary tasks associated with information systems whilst driving (the primary task), can increase the demands placed on individuals’ limited attention resources and modalities. If the in-vehicle information system does not closely meet the users’ needs, and is not correctly installed and integrated within the vehicle, the potential exists for additional cognitive and physical load placed on the user. This can lead to the user potentially making errors, taking risks and can lead to failures in the execution of the primary task. Due to the rapid development of ‘bolt on’ vehicle information systems, at present, users are often not provided with sufficient ‘up to date’ information and guidance, in a usable format, to assist them with selecting the optimum device and then integrating it safely (ie ergonomically) within their vehicles. The aim of this research is therefore to develop an information aid for drivers of vehicles (the primary users) to help them choose, install and use (whilst driving) additional information systems within their vehicles, with minimum detriment to their own safety and the safety of those within the surrounding environment. An analytical approach has been taken by the researcher, who has adopted and modified a usability engineering model to investigate the confounding factors associated with the selection, integration and safe use of ‘bolt-on’ in-vehicle information systems. The information resulting from the investigation will form the basis for a usable, accessible information aid to be produced. |
