Item Computerized assessment approach for evaluation computer interaction performance.(Springer Berlin Heidelberg, 2006-01-01) Chen, M. C.; Chu, C. N.; Wu, T. F.; Yeh, C. C.This study presents a computerized assessment approach for evaluating a subject’s pointing and selecting proficiency using computer input tools, to aid access tool selection for users with severe disabilities. The CAT system consists of three subsystems. The CAT system not only provides clinicians with an objective means of evaluating clients’ specific mouse operating difficulties, but also allows them to compare the performance improvement made by a client make during the device selection and training period. The client’s performance in each assessment task is assessed on the basis of speed, accuracy and efficiency. Besides introducing the CAT system, this study also describes an example of adopting the CAT system to assist a client to select a suitable pointing device.Item Characteristics and solutions of digital divide for People with physical impairments in Taiwan(Springer Berlin Heidelberg, 2008-01-01) Yeh, Y. M.; Wu, T. F.; Meng, L. F.; Chen, M. C.; Wang, H. P; Wu, J. G.; Chu, C. N.; Lin, Y. L.; Yeh, C. C.The purpose of this study is to narrow down the digital gap between people with and those without physical impairments in Taiwan. To better understand the need of the digital learning for people with physical impairments, the authors have created the digital characteristic assessment scale, digital need assessment scale, and developed the mouse training system and on-screen keyboard assessment system. In order to comprehend the performance and practicability of the scales and systems, this integrated project have also applied these tools to evaluate and train the clients with muscular dystrophy and cerebral palsy.Item A kinematic analysis of directional effect on trackball mouse control in novel normal users: An alternating treatments single subject design(Springer Berlin Heidelberg, 2007-01-01) Meng, L. F.; Chen, M. C.; Chu, C. N.; Yeh, C. C.; Wu, T. F.To know the directional efficiency of cursor moving is important for the purpose of guiding the rearrangement of icons and toolbars in the window environment. This rearrangement resolution can achieve better computer access especially in the clients with quadriplegia. However, the information about the directional efficiency of cursor movement is not clear even in the typical persons. Therefore, before surveying the quadriplegics, typical persons were researched in this study. Four typical persons simulated quadriplegics to operate trackball with their right dorsal hand and the kinematic parameters of cursor moving were measured. The single subject experimental research (SSER) with alternating treatments design was used to compare the effects of four cursor moving direction (right to left, down to up, left to right, and up to down) on the kinematic variables. The prior auto-correlation coefficients and Bartlett’s ratio values were computed to make sure there was no any series dependence between measuring points before conducting parametric one-way repeated measures ANOVAs. From analyzing the parameter of deviation from the straight line, velocity, movement unit and execution time, the efficiency to move on the horizontal direction (left to right or right to left) was better than move on the vertical direction (up to down or down to up). To further know the cursor kinematic performances in patients with quadriplegics will be important.Item Embedding Expert System into a Computerized Assessment Tool for Mouse Proficiency(Springer Berlin Heidelberg, 2007-01-01) Yeh, C. C.; Chen, M. C.; Chu, C. N.; Cko, C. C.; Wu, T. F.This paper described an assessment system which embedded expert system based on theidea of neural network. Authors developed a computerized assessment tool for mouse operating proficiency and applied into clinical service. The result indicated that the objective tool had great contribution for selecting suitable pointing device for the client. However, clinical also found that comparing the effectiveness between different device and operation environment by some parameters was labor consuming. Expert system may be an available solution for clinical professional to select suitable pointing and selecting device more efficiently. Therefore, this study aimed to develop an embedding expert system into a computerized assessment tool for mouse operating proficiency.Item The directional effects on cursor dragging kinematics(IJCSNS, 2007-03-01) Meng, L. F.; Chen, M. C.; Chu, C. N.; Wu, T. F.; Lu, C. P.; Yeh, C. C.; Yang, C. Y.; Lo, C. Y.There has no study to substantiate the kinematical characteristics of cursor dragging movement. In this present study, we developed a computerized measuring program and used the experimental research method to explore the effect of moving direction on kinematics of cursor dragging in 24 normal participants. The results of multiple one way repeated measures ANOVAs and post hoc LSD tests demonstrated that dragging direction had effects on movement time and movement unit. Dragging leftward showed better efficiency than dragging upward and downward. These directional effects partially clarify how the dragging performances were influenced by the moving direction. Moreover, it can guide us to re-arrange the toolbars and icons under window interface, especially for individuals with physical disability whose performances can be easily interrupted while controlling cursor in specific directions.Item Using expert system to assist mouse proficiency assessment(Springer Berlin Heidelberg, 2008-01-01) Yeh, C. C.; Chen, M. C.; Yeh, Y. M.; Wang, H. P.; Chu, C. N.; Ko, C. C.This paper described how to use expert system to assist conducting mouse proficiency assessment. The expert system was based on neural network approach. The current study shows the result of analyzing cursor measurement between able-bodied and cognitive disability users. The result of evaluation indicated that this expert system may be an available solution for clinical professional to propose the suggestion for selecting suitable device or adjusting user environment conditions. The authors also provided some suggestions for the future research.Item Characteristics and solutions of digital divide for people with physical impairments in Taiwan(Springer Berlin Heidelberg, 2008-01-01) Yeh, Y. M.; Wu, T. F.; Meng, L. F.; Chen, M. C.; Wang, H. P.; Wu, J.G.; Chu, C. N.; Lin, Y. L.; Yeh, C. C.The purpose of this study is to narrow down the digital gap between people with and those without physical impairments in Taiwan. To better understand the need of the digital learning for people with physical impairments, the authors have created the digital characteristic assessment scale, digital need assessment scale, and developed the mouse training system and on-screen keyboard assessment system. In order to comprehend the performance and practicability of the scales and systems, this integrated project have also applied these tools to evaluate and train the clients with muscular dystrophy and cerebral palsy. To fulfill the need of training the clients and providing appropriate assistant facilities, the alternative input device and the adapted web platform have been developed. The result validates the feasibility of both software and hardware developed by our implementation.
