Abstract

The disclosed embodiments include wearable devices and methods for performing courier services. In one implementation, the device includes a depth camera for detecting object depths in a field of view, a scanner for decoding visual codes, a speaker for producing audible sounds in response to an electrical signal, memory, and a processor. The processor may execute instructions to detect a scanning event based on a first signal received from the depth camera, determine a scan region associated with the scanning event, provide a second signal to the scanner causing the scanner to decode a visual code located within the scan region, generate scan data based on a third signal received from the scanner, and provide a fourth signal to the speaker causing the speaker to emit a notification sound. The wearable device may also capture signatures, dimension objects, and disable device functions based on time and place restrictions.
