| Abstract | We report on the results of a user study conducted to evaluate three different wearable input devices for menu-selection tasks in aircraft maintenance. Participating subjects were recruited from real maintenance workers (domain experts) and “typical ” subjects of scientific studies (layman). An unfamiliar data glove device using gestures was found to outperform natural speech interaction. Besides suffering from handling problems, speech interaction was found inappropriate for domain experts due to lacks in education; laymen did not suffer from this. Further, our evaluation suggests the necessity to include real end-users in studies for industrial applications to get results able to uncover application domain specific constraints. Study outcomes significantly differed between domain experts and laymen; suggesting to take social and educational backgrounds of endusers into account when designing user studies that should impact professional wearable computing applications. 1. |
