    Google Glass++: Evaluating Multimodal Alarms on Google Glass
    (Mensch und Computer 2019 - Tagungsband, 2019) Cobus, Vanessa; Busse, Steffen; Heuten, Wilko
    Around 350 alarms per patient a day make intensive care units a loud, stressful, and highly cognitive demanding working environment for nurses. Each alarm needs to be identified and evaluated regarding its urgency which requires to interrupt nursing tasks. Alarm fatigue is a prominent result of alarm exposure and a well-known problem for caregivers, causing a desensitization and delayed response time for alarms. To counteract this issue, we suggest to forward patient alarms and alarm relevant information just to the responsible nurse, using head-mounted displays. In a first user study, we evaluated the suitability of patient relevant information displayed via Google Glass EE in combination with peripherally visual and audible alarms during nursing specific loads. Therefore, we enhanced Glass with a peripheral light display. For both conditions (light/sound), the readability of the display, and the alarms' identifiability and distraction, were rated as good. Finally, our prototype was rated as comfortable.

    Lumicons: Mapping Light Patterns to Information Classes
    (Mensch und Computer 2015 – Proceedings, 2015) Rauschenberger, Maria; Matviienko, Andrii; Cobus, Vanessa; Timmermann, Janko; Müller, Heiko; Löcken, Andreas; Fortmann, Jutta; Trappe, Christoph; Heuten, Wilko; Boll, Susanne
    The current development of ambient light systems lacks an evaluation and guidelines in the design process. We present a study design with two complementary parts, which aims to fill the gaps in the understanding of information encoding via light. In the first part of our study we want to find out light patterns that represent different types of everyday information, and in the second part we want to verify the appropriate mappings of these light patterns suggested by participants. An appropriate mapping of the light pattern should be perceptible and distinct with a degree of attention arousal and aesthetic appearance. The goal of the study is to derive light patterns and guidelines for building new light systems and applications.
