The KidsRoom is a perceptually-based, interactive, narrative playspace for children. Images, music, narration , light, and sound eeects are used to transform a normal child's bedroom into a fantasy land where children are guided through a reactive adventure story. The fully-automated system was designed with the following goals: (1) to keep the focus of… (More)
Ten different feature vectors are tested in a gesture recognition task which utilizes 3D data gathered in real-time from stereo video cameras, and HMMs for learning and recognition of gestures. Results indicate velocity features are superior to positional features, and partial rotational invariance is sufficient for good performance.
A new method for representing and recognizing human body movements is presented. Assuming the availability of Cartesian tracking data, we develop techniques for representation of movements based on space curves in subspaces of a " phase space. " The phase space has axes of joint angles and torso location and attitude, and the axes of the subspaces are… (More)
T he KidsRoom is a fully automated and interactive narrative playspace for children developed at the MIT Media Laboratory. Built to explore the design of perceptually based interactive interfaces, the Kids-Room uses computer vision action recognition simultaneously with computerized control of images, video, light, music, sound, and narration to guide… (More)
We believe the KidsRoom is the first multi-person, fully-automated, interactive, narrative environment ever constructed using non-encumbering sensors. The perceptual system that drives the KidsRoom is outlined elsewhere(Bobick et al. 1996). This paper describes our design goals, successes, and failures including several general observations that may be of… (More)
