Interactive plush toys, such as ActiMates Barney, raise new ethical concerns that we as HCI professionals need to address and understand. This panel is designed to bring those concerns to the forefront and allow panelists and audience members to debate key issues. The panel includes people with expertise in creating interactive plush toys, creating software for children, and investigating ethical issues of technology.

Computation visualization or algorithm animation is becoming an increasingly popular and effective way of teaching, debugging, and analyzing algorithms. Over the past ten years, several algorithm animation systems have been produced. Proposed here is a new approach and framework for visualizing three-dimensional algorithms or computations. Implemented on a prototype algorithm animation system, this framework, termed the vector-guided view, produces insightful visualizations of three-dimensional computation by effectively solving the problems of 3D scene navigation. The creation of this framework was motivated by the desire to produce visualizations of an increasingly large and complex set of rendering algorithms now ubiquitous in the field of computer graphics. To show the potential of this framework, a dynamic visualization of a recursive ray-tracing program has been created. A brief summary of the algorithm animation system is presented.

Video games can be used as a motivational tool to promote exercise among individuals with disabilities. The velocity of the wheels of a stationary wheelchair is used as a control interface for video games. This interface is implemented with an entirely digital system. An MC68HC11A1 microcontroller is used to perform quadrature on the input of two optical encoders and dynamically adjust two X9C104P digital potentiometers. The result is a virtual joystick which is controlled by the speed and direction of the wheelchair wheel rotation. This system can be mounted to any personal computer game port and used for virtual reality applications as well as games.
