虽然有许多条形码读取器可用于在超市或家中通过移动电话(例如，红色激光iPhone应用程序)识别产品，但盲人或视障人士无法使用此类读取器，因为他们依赖来自用户的视觉反馈来使条形码在相机的视野中居中。我们描述了一款移动电话应用程序，它使用手机的内置摄像头实时引导视障用户找到包裹上的条形码。一旦系统定位到条形码，系统就会用音频信号提示用户使摄像机更接近条形码，直到摄像机能够解析条形码，然后对其进行解码，并使用文本到语音的方式朗读相应的产品信息。一名盲人志愿者的实验证明了我们系统的概念，该系统允许志愿者定位条形码，然后将条形码转换为产品信息，并向用户宣布。我们成功地测试了一系列常见产品，以及用户生成的条形码，这些条形码标记了可能没有条形码的家用物品。
While there are many barcode readers available for identifying products in a supermarket or at home on mobile phones (e.g., Red Laser iPhone app), such readers are inaccessible to blind or visually impaired persons because of their reliance on visual feedback from the user to center the barcode in the camera’s field of view. We describe a mobile phone application that guides a visually impaired user to the barcode on a package in real-time using the phone’s built-in video camera. Once the barcode is located by the system, the user is prompted with audio signals to bring the camera closer to the barcode until it can be resolved by the camera, which is then decoded and the corresponding product information read aloud using text-to-speech. Experiments with a blind volunteer demonstrate proof of concept of our system, which allowed the volunteer to locate barcodes which were then translated to product information that was announced to the user. We successfully tested a series of common products, as well as user-generated barcodes labeling household items that may not come with barcodes.
