– Studies of human-robot interaction have shown that operators rely heavily upon the video stream, to the exclusion of all other information on the interface. We have created a new interface that fuses information on and around the video window to exploit this fact.
– Robot systems can have autonomy levels ranging from fully autonomous to teleoperated. Some systems have more than one autonomy mode that an operator can select. In studies, we have found that operators rarely change autonomy modes, even when it would improve their performance. This paper describes a method for suggesting autonomy mode changes on a robot… (More)
Design of educational multimedia rarely starts from scratch, but rather by attempting to reuse existing software. Although redesign has been an issue in research on evaluation and on learning objects, how it should be carried out in a principled way has remained relatively unexplored. Furthermore, understanding how empirical research on information and… (More)
This paper describes an integration of geographic information systems (GIS) and multimedia technologies to transform the ways K-12 students learn about their local communities. We have augmented a digital camera with a global positioning system (GPS) and a digital compass to record its position and orientation when pictures are taken. The metadata are used… (More)
This paper describes an integration of geographic information systems (GIS) and multimedia technologies to create opportunities for people to explore the history of their cities. We have augmented a digital camera with a global positioning system (GPS) and a digital compass to record its position and orientation when ordinary photographs are taken. The… (More)
