Perceived realism of haptic rendering methods for bimanual high force tasks: original and replication study.

Realistic haptic feedback is a key for virtual reality applications in order to transition from solely procedural training to motor-skill training. Currently, haptic feedback is mostly used in low-force medical procedures in dentistry, laparoscopy, arthroscopy and alike. However, joint replacement procedures at hip, knee or shoulder, require the simulation of high-forces in order to enable motor-skill training.

Two is Better Than One. Improved Attention Guiding in AR by Combining Techniques.

Search tasks in production environments have been shown to be significantly improved by attention guiding techniques in augmented reality (AR). In mobile use cases, head-mounted displays support context-sensitive and flexible search tasks. To improve search time and navigation efficiency, first concepts like attention funnel and spherical wave based guidance techniques have been tested successfully in comparison to simple arrow navigation.

Get a grip: multi-method evaluation of handles for tablets on the shop floor.

Tablets on the shop floor need handles because user requirements for handling differ from tablet usage in leisure time. The ergonomics of such handles is under-researched, resulting in a lack of methods for their design and evaluation. In this paper, we present a multi-method evaluation of handles for a shop floor tablet.

Mitigating passive fatigue during monotonous drives with thermal stimuli: Insights into the effect of different stimulation durations.

Driving on monotonous roads has been shown to cause passive fatigue as even non-sleep-deprived drivers suffer from the lack of stimuli. Consequently, alertness is reduced and the risk of accidents increases. To counteract this risk, measures need to be taken to mitigate driver fatigue.

Psychophysiological responses to short-term cooling during a simulated monotonous driving task.

For drivers on monotonous routes, cognitive fatigue causes discomfort and poses an important risk for traffic safety. Countermeasures against this type of fatigue are required and thermal stimulation is one intervention method. Surprisingly, there are hardly studies available to measure the effect of cooling while driving.

Open innovation in health care: analysis of an open health platform.

Today, integration of the public in research and development in health care is seen as essential for the advancement of innovation. This is a paradigmatic shift away from the traditional assumption that solely health care professionals are able to devise, develop, and disseminate novel concepts and solutions in health care. The present study builds on research in the field of open innovation to investigate the adoption of an open health platform by patients, care givers, physicians, family members, and the interested public.
