There are 40 million blind people worldwide and over 120 million people have significant visual problems. Their use of mobile computing fits the same profile as the general population; most younger people with are conversant with modern technologies, and increasingly older people too. Smartphones and tablets have accessibility features built in but they are limited to text and buttons - there is no way for visually impaired users to visualise maps, imagery or the 3d imagery on next generation tablets. Active tactile displays can present this information but are bulky and expensive (>£10,000). We will investigate the feasibility of a new mobile device interface that allows visually impaired users to interact naturally with visual information while on the move. As with a tactile interface, this new approach allows the user to scan the information by running their finger over the array. However, instead of raising pins to represent the imagery, audio signals will represent pixels in the image, using pitch and pan. This extends existing accessibility features, allowing maps and images to be easily “visualised” and particularly 3D images captured by the platform's 3D camera

全世界有4000万盲人，超过1.2亿人有严重的视力问题。他们对移动计算的使用与普通人群的情况相同；大多数年轻人熟悉现代技术，老年人也越来越熟悉。智能手机和平板电脑有内置的辅助功能，但它们仅限于文本和按钮——在下一代平板电脑上，视力受损的用户无法看到地图、图像或3d图像。主动触觉显示器可以显示这些信息，但体积庞大，价格昂贵（1万英镑）。我们将研究一种新的移动设备界面的可行性，该界面允许视障用户在移动时自然地与视觉信息进行交互。与触觉界面一样，这种新方法允许用户通过手指在阵列上滑动来扫描信息。但是，音频信号将使用音调和平移来表示图像中的像素，而不是提高引脚来表示图像。这扩展了现有的可访问性功能，允许地图和图像轻松“可视化”，特别是由平台的3D相机捕获的3D图像
