Amazon delivery workers are using connected glasses that can take thousands of photos during a single delivery route. These images are uploaded to Amazon's artificial intelligence platform called Wellspring, which the company hopes will help it map neighborhoods more accurately and speed up deliveries. The glasses, introduced a year ago, were designed to guide workers to customers' doors without needing to use their phones. Viraj Chatterjee, an Amazon executive overseeing the project, told Bloomberg that the glasses automatically take still images at regular intervals as soon as a worker leaves the delivery truck. On a typical day, this results in "several thousand" photos. During a pilot phase, more than 275,000 packages have been delivered using the glasses, and Amazon plans to provide them to 5,000 delivery workers by the end of 2026 and over 20,000 by 2027. The images collected include views of building facades and private gardens, though Amazon says it automatically blurs faces and license plates. However, critics argue that the system's purpose is to link each image to a specific customer's address, making the anonymity of the photos questionable. Amazon has not specified the resolution of the photos or how frequently they are taken, but estimates suggest an image is captured every few seconds. The company also has not said how long it will keep the photos or whether customers can access or delete them. When asked about police access, an Amazon spokesperson said a warrant would be sufficient for investigators to obtain the images. Amazon insists the glasses are not for surveillance but to improve the delivery experience and reduce errors. However, concerns have been raised about the potential for misuse. In February, Amazon faced backlash after it was revealed that it had shared videos from its Ring doorbell cameras with American police. This led to a temporary halt in the practice. Meanwhile, delivery workers are aware of the monitoring systems in their vehicles, which track driving behavior and have been used to adjust pay. While Amazon claims the glasses are optional, some workers are skeptical, given the pressure to meet delivery targets and the risk of being dismissed for poor performance. Some delivery workers suspect that the images collected by the glasses may be used to train delivery robots. Amazon acquired the Swiss startup Rivr in March, which designs robots capable of navigating stairs and delivering packages. While Viraj Chatterjee did not confirm any specific use for the images, he acknowledged that the technology could be used to train such robots. As with past controversies, the public may eventually move on, but for now, the use of connected glasses continues to raise questions about privacy and surveillance.
