摘要
本文介绍了一种盲人识字辅助装置的实现方法。盲人对于文字和图像的获取途径来自于触觉,同时,在识字的过程还需要语音提示来辅助,说明所触摸文字的含义。本系统能完成上述功能,系统由盲人显示器、智能语音发声装置、SD卡存储等模块组成。其中,盲人显示器是系统的核心组成部件,通过二维运动控制等手段,在有字迹的像素点处放置颗粒物,从而形成突起,供盲人触摸识别文字或图像。本系统对于盲人识字及认知图像有着重大意义。
This article introduces a method of the assistant device to help the blind’s literacy. The blind’s access to the words and images depends on their sense of touch, while the process of literacy also require voice prompt as assistance, explaining the meaning of the word touched. This system manages to accomplish the functions mentioned above, which consists of the blind monitor, intelligent voice play device, SD card storage and other modules. Among all the modules, the blind monitor is the core component part of the system. By means of two-dimensional motion control, particulate matters were placed in any pixels with handwriting, thus forming protuberance to help the blind to recognize the words and images. The system is of great significance to help realize the blind’s recognition of words and images.
