During payload operations astronauts are guided by sequential directives displayed on a laptop computer using an exocentric presentation scheme for task guiding. Such an approach forces the astronaut to constant changes of focus that can cause loss of concentration and attention, as well as can be the primary reason for sequence errors resulting in a faulty task termination. To ease astronauts’ work and ensure successful task performance new interface technologies are required. By bridging the gap between the physical reality and digital information, Augmented Reality (AR) keeps the focus on the task to fulfill and offers user- centered operations by an egocentric display. Beside the display, AR interface can differ in providing the visual information for localizing users’ attention. While egocentric visualizations maintain the principal characteristic required for AR interfaces by 3D registered information, exocentric visualizations are presented as head-up display information and approved methods to navigate the user towards off-screen objects. Using a visuomotor task (visual search, operation task) we will investigate the influence of altered gravity on human performance and workload by comparing exocentric with egocentric displays and presentation schemes in a within-subject user study. To differentiate visuomotor deficits we will use common performance metrics. Workload effects will assess with subjective, physiological and secondary task performance. For evaluating the physiological workload we intend to assess and analyze cardiovascular parameters such as the heart rate variability, the heart frequency and the blood pressure. We expect that under altered gravity, especially under short-term microgravity, the egocentric presentation of task directives using the Augmented Reality condition outperforms exocentric conditions by increased performance and decreased workload. We will also perform head movement analysis resulted from the visual search process and expect significant findings for the AR condition that offers visual search by egocentric navigation providing head movements in given horizontal, vertical and oblique directions.

This project is a collaboration with the German Aerospace Center (DLR) and explores the influence of micro- and hypergravity in parabolic flight during the performance of selecting virtual objects in Augmented Reality (AR) environments, which enable the enrichment of the physical world with virtual information. Such interfaces should enhance the user’s perception of the real world and thereby supply support for service and maintenance tasks at complex technical facilities. One important aspect of research in AR environments investigates the user’s interaction with real and virtual objects in an intuitive and natural manner.

Pointing to a virtual object in 3D physical reality is one of the basic interaction techniques in virtual environments. Using common input devices (e.g., mice, keyboard) is not suitable for mapping control tasks in 3D AR environments. To apply AR user interfaces to space flight missions has a great potential for future space operations. During a mission the astronaut’s handling of displays and control items depends on an easy and intuitive usability. Our experiment will investigate the ability of a human to pick virtual objects in 3D space under micro-g and hyper-g conditions during parabolic flight. This will enable the measurement of the quality and quantification while performing this task in order to evaluate human performance in virtual object selection in physical reality.

We have developed an experimentation task that includes pointing to a virtual keyboard to investigate different arrangements modalities of interactive AR interfaces. The results of the experiment will allow the identification of special requirements and early consideration of the influence of different acceleration conditions (micro-g, hyper-g) during our currently development stage of AR user interfaces for future aerospace applications.

Supported by the European Space Agency (ESA) and the German Federal Ministry of Economics and Technology (BMWi) we have carried out parabolic flight experiments in May 2012 and June 2013.
