The impact of different visual feedback presentation methods in a wearable computing scenario

Abstract

Interfaces for wearable computing applications have to be tailored to task and usability demands. Critical information has to be presented in a way allowing for fast absorption by the user while not distraction from the primary task. In this work we evaluated the impact of different information presentation methods on the performance of users in a wearable computing scenario. The presented information was critical to fulfill the given task and was displayed on two different types of head mounted displays (HMD). Further the representations were divided into two groups. The first group consisted of qualitative representations while the second group focused on quantitative information. Only a weak significance could be determined for effect the different methods used have on the performance but there is evidence that familiarity has an effect. A significant effect was found for the type of HMD. © 2009 Springer Berlin Heidelberg.
