    Recently, the number of children having autism disorder increases rapidly all over the world. Computerbased training (CBT) has been applied to autism spectrum disorder treatment. Most CBT applications are based on the standard WIMP interface. However, recent study suggests that a Tangible User Interface (TUI) is easier to use for children with autism than the WIMP interface. In this paper, the efficiency of the TUI training system is considered, in comparison with a conventional method of training basic geometric shape classification. A CBT system with TUI was developed using standard computer equipment and a consumer video camera. The experiment was conducted to measure learning efficacy of the new system and the conventional training method. The results show that, under the same time constraint, children with autism who practiced with the new system were able to learn more shapes than those participating in the conventional method. © 2008 IEEE.

    In this paper, the design of a computer-based training (CBT) system for low-functioning autistic children is addressed. The emphasis is on ease-of-use and learning efficiency of CBT systems with different interaction styles, namely the WIMP (Window Icon Menu Pointing Device) and TUI (Tangible User Interface) interaction styles. Two WIMP-based CBT systems with different pointing devices were involved in the study. The first system applied a standard computer mouse as a pointing device, while the second one employed a touch screen instead. For the TUI-based CBT system, a tabletop setting was adopted. Based on the known characteristics of TUI and children with autism, as well as related cognitive and learning theories, the benefits of TUI for low-functioning autistic children have been investigated. Elementary skill teaching was chosen as a case study for performance evaluation of these CBT systems. Empirical results show that the touch-based and TUI-based systems offered much better ease-of-use performance than that of the mouse-based system. Regarding learning efficacy, experimental results show that the TUI-based system achieved higher skill improvement, as compared with the WIMP-based system and a non-computer training method. Some guidelines and suggestions for the design of a TUI-based system for children with autism are summarized. © 2011 Springer-Verlag London Limited.

    Computer-based training has been applied to autism spectrum disorder treatment. Most CBT applications are based on the standard WIMP interface. However, autistic children have their own unique learning style. They are more attracted to a tangible user interface device, such as a steering wheel used in a computer game, instead of a standard mouse. In this paper, two versions of computer-based training application for autistic children were compared in terms of learn ability. One of them is based on a standard WIMP interface, while the other adopts a tangible user interface. The basic shape matching task was chosen as a case study. The point-and-click interaction style was chosen for WIMP interface while the grasp-and -move style was adopted for tangible user interface. Both systems display a picture of a randomly chosen geometric shape and then ask a user to pick one of the provided icons (a wood block for the tangible UI case) to match the shape of the object shown on screen. Experiment was carried out to compare the ease of use of the two interfaces as perceived by autistic children. The results show that the tangible user interface was easier and more enjoyable to use than the WIMP interface. ©2007 IEEE.
