The objective of this research was to assess the effectiveness of using a multi-modal interface for adaptive automation (AA) of human control of a simulated telerobotic (remote-control, semi-autonomous robotic) system. We investigated the use of one or more sensory channels to cue dynamic control allocations to a human operator or computer, as part of AA,(More)
OBJECTIVE To investigate the effect of optic flow on gait behavior during treadmill walking using an immersive virtual reality (VR) setup and compare it with conventional treadmill walking (TW) and overground walking (OW). BACKGROUND Previous research comparing TW with OW speculated that a lack of optic flow (relative visual movement between a walker and(More)
The Internet connects millions of computers worldwide, and provides a new potential working environment for remote-controlled telerobotic systems. The main limitation of using the Internet in this application is random delays between communicating nodes, which can cause disturbances in human–machine interaction and affect telepresence experiences. This is(More)
Real-time operator workload assessment and state classification may be useful for decisions about when and how to dynamically apply automation to information processing functions in aviation systems. This research examined multiple cognitive workload measures, including secondary task performance and physiological (cardiac) measures, as inputs to a neural(More)
Force-based touch input is a novel input method for automotive interfaces. It constitutes an efficient and effective way of in-car interaction with an added degree of freedom. Research on force-based in-car interfaces is still scarce. Recommendations such as gesture sets or interaction languages that could guide future implementations have not yet been(More)
Steering wheel controls have become an essential interface for interacting with in-car human machine interfaces. The increase in both number and complexity of features in the car challenges the scalability of button-based mechanical steering wheel interfaces. Alternatives such as touch input are making their way into steering wheels of mass production cars.(More)
Current automotive interfaces rely heavily on touchscreen interfaces which leverage simple and intuitive direct touch interaction. Since input and output are co-located, displays have to be positioned within hand's reach. When the display is outside the reach envelope, a touchpad has been used as a control device. Current implementation of touchpads in cars(More)
With the spread of mobile device fingerprint sensors, there is an opportunity to allow interaction beyond biometric authentication on the same device. The fingerprint sensor can detect simple gestures, enabling an additional gestural input method. We conducted user research sessions with ten people to understand the usefulness of a fingerprint sensor that(More)
We evaluated the efficacy of a computer-based situation awareness (SA) measurement system for training dismounted infantry SA in an urban terrain virtual reality (VR) simulation. Based on past research, we hypothesized that the SA measures would be sensitive to individual (squad leader) differences, and that the frequency of specific probes would reveal(More)
