Over the past 20 years or so, researchers have, in a number of ways, considered how studies of talk and interaction might inform the design of new technologies. In this article, we discuss a “technical intervention” where studies of visual and material conduct informed by conversation analysis shaped the design and development of a prototype commun...
Conference Paper
During hand-skill learning, it is important for the learner to manipulate a tool with the appropriate amount of force. Haptic training systems in which a tool is directly actuated are therefore undesirable due to the fact that the force applied to the tool is assisted by an actuator. We report a method in which we have replaced guiding by a tool wi...
