Despite active research in input device development, the visually impaired community still find difficulty in interacting with computers. Braille and other conventional methods have limitations while inputting data to the computer due to their vision loss. Gesture-based interaction can offer them a new vista of computer interaction. However, one needs to consider their performance and preference towards hand gesture. So, a gesture elicitation study is done with 25 visually impaired users. A quantitative rating analysis is performed with them, and an optimal set of gestures is obtained. Further, a dactylology is proposed using which visually impaired users can interact with computers. A recognition module is also presented to recognise the dactylology symbols.

利用手势使视觉障碍者能够进行计算机交互

尽管在输入设备开发方面进行了积极的研究，但视障人士在与计算机交互方面仍然遇到困难。盲文和其他常规方法由于视力下降而在将数据输入到计算机时存在局限性。基于手势的交互可以为他们提供计算机交互的新视野。但是，需要考虑其性能和对手势的偏爱。因此，对25位视障用户进行了手势启发研究。使用它们进行定量评估分析，并获得最佳手势集。此外，提出了一种指纹学，使用它可以使视力障碍的用户与计算机进行交互。还提供识别模块以识别指纹符号。
