Yun Lung Lin; Ting-Fang Wu; Ming-Chung Chen; Yao-Ming Yeh; Hwa-Pey Wang

This study aims to explore the effectiveness of a scanning on-screen keyboard for persons with severe motor disabilities. In order to enhance the typing performance, the on-screen keyboard employs the group-row-column scanning and a frequency-of-use layout. Besides the international alphabetical layout, the on-screen keyboard also provides two Chinese selection layouts for Chinese users. The usability evaluation was carried out with simulations and experiments. The usability evaluation was conducted to compare the performance with that of the QWERTY layout of block scanning built in Microsoft Windows XP. The results demonstrated that the performance of using the scanning on-screen keyboard was better than that of using the Windows XP. No significant difference between the error rates of the two different keyboards was found.

This paper substantiates the process of helping the clients with motor disabilities to operate computer. A team with multiple professionals from different disciplines served eight persons with quadriplegics diagnosed as Charcot-Marie-Tooth Disease, Amyotrophic Lateral Sclerosis (ALS), Athetoid Cerebral Palsy, Cervical Spinal Cord Injury and Muscular Dystrophy respectively. Based on the computer access approach (CAA), the limitations and strengths of motor control, the difficulties of operating computer and the context to support accessibility were evaluated. Furthermore, the evaluation results guided the configuration of computer system to be modified, possibly combined with changing anatomical control site. Finally better accessibility for each person was achieved. It can be concluded that CAA processed by an integrated team can greatly help in solving accessibility problems for quadriplegic.

Effect of translucency on transparency and symbol learning for children with and without cerebral palsy

Chih-Hsiung Huang; Ming-Chung Chen

Based on the concept of iconicity, the iconicity hypothesis was emphasized for decades. The aims of this study were to explore the effect of translucency on transparency and symbol learning for children with and without cerebral palsy. Twenty children with cerebral palsy and forty typical peers participated in the study. Ten symbols with high translucency and ten with low translucency were used as experimental material. The results of transparency testing demonstrated the positive relationship between translucency and transparency. The effect of translucency on symbol learning was supported partially, all children with and without CP could learn the low translucent symbols only after two teaching sessions, or three sessions at most. The authors also provided some suggestions for further study based the results of this study.

A flexible on-screen keyboard: dynamically adapting for individuals' needs

Yun Lung Lin; Ming-Chung Chen; Ya-Ping Wu; Yao-Ming Yeh; Hwa-Pey Wang

This study was to design an alternative on-screen keyboard and evaluate the efficacy of this innovative layout design for people with severe physical disability. The matrix keyboard layouts was designed based on human computer interaction. A repeated experiment was performed to compare the speed and accuracy of text entry with point-and-click input method between the matrix on-screen keyboard and the Windows XP QWERTY virtual keyboard. Data analysis revealed that the matrix on-screen keyboard provided better performance for the participant. The result also indicates that layout adaptation assessment is a valid tool to confirm proper layout size for users and that alphabetic order is better than QWERTY order for a novice user to learn a new on-screen keyboard. A usability study was undertaken to evaluation the performance of the double click instead of the point-and-click plus Shift key input method. The possible causes of the results and suggestions for further studies are discussed.

Is digital divide an issue for students with learning disabilities

Ting-Feng Wu; Ming-Chung Chen; Yao-Ming Yeh; Hwa-Pey Wang; Sophie Chien-Huey Chang

Exploring digital divide between students with learning disabilities (LD) and peers.No difference was found in ICT access between children with and without LD.A difference was found in ICT competencies between children with and without LD.Typical students enhanced ICT skills gradually, but those with LD did not.Specific ICT instruction programs should be provided to children with LD. The purpose of this study was to examine if digital divide exists between elementary school aged children with learning disabilities (LD) and their nondisabled peers in Taiwan. A self-reported questionnaire regarding information and communication technology (ICT) access and ICT competency, Scale of Digital Participation of Elementary School Students, designed by the authors, was used to collect data. Totally, 117 students with LD and 117 peers without disabilities were recruited in this investigation and were conducted with the questionnaire. The results indicated that there was no significant difference in the opportunities to access computers and the Internet at home and at school between children with and without LD. However, there was a significant difference found in ICT competencies between children with and without LD. Moreover, students without LD enhanced their computer competency gradually year by year, but students with LD eventually did not. The findings of this study supported the notion that mere provision of ICT access is not sufficient for children with LD to master ICT skills. A specific designed ICT instruction programs should be provided to children with LD. Finally, suggestions for future studies were also discussed.

Computer access is always a concern due to the fact that computer skills are often listed among the basic requirements for job application. In Taiwan, many people with disabilities do not get job offers because regular computer devices are not designed for their special needs. To help these people, the Adaptive Computer Technology Service Team (ACTST) was established to design and provide individualized needs evaluations and computer skill training. This paper aims to report the results of our efforts and discuss future plans.
