Occupational therapists are becoming increasingly involved with interface assessments. This involvement is improving the ability of persons with physical disabilities to interact with computers, augmentative communication aids, and other devices. The ability to use these devices facilitates participation in activities that would otherwise be much more difficult to pursue, such as communication, education, work, and recreation. The purpose of the present study was to systematically compare three basic modes of scanning--automatic, inverse, and step--with the use of a single-subject experimental design. Six subjects--3 with spastic and 3 with athetoid cerebral palsy--from a local school volunteered for the study. Results indicated that the 3 subjects with spastic cerebral palsy had the greatest difficulty using the automatic scanning mode. The 3 subjects with athetoid cerebral palsy had the most difficulty using the step scanning mode. The results of this study suggest that clients should attempt each scanning mode and that their performance with each mode be compared to ensure the most appropriate recommendations.
职业治疗师越来越多地参与界面评估。这种参与正在提高身体残疾者与计算机、辅助沟通设备及其他装置进行交互的能力。使用这些设备的能力有助于参与那些否则将难以开展的活动，如沟通、教育、工作和娱乐。本研究的目的是采用单受试者实验设计，系统地比较三种基本扫描模式——自动、反向和步进。来自当地一所学校的六名受试者——3名痉挛型脑瘫患者和3名徐动型脑瘫患者——自愿参与了该研究。结果表明，3名痉挛型脑瘫患者在使用自动扫描模式时遇到的困难最大。3名徐动型脑瘫患者在使用步进扫描模式时遇到的困难最大。本研究结果表明，客户应尝试每种扫描模式，并比较他们在每种模式下的表现，以确保给出最恰当的建议。
