Portable information and communication terminal

Abstract

This device is a portable information and communication terminal equipped with authentication and communication functions. This device is worn by being placed on the wrist. When the user approaches a speaker or other device, authentication is performed using personal information transmitted from this device, and music is selected based on the user's personal information, such as their musical preferences. In addition, the speaker or other device determines the user's location based on the location information transmitted from this device and accurately directs the playback sound. Because this device has an elliptical shape when viewed from the front, it fits comfortably on the user's wrist and can be worn for long periods of time. Furthermore, because this device has a flattened elliptical cross-section, it is easy to house components such as chips in the gently curving parts. The oval-shaped part in the center of the "BB cross-sectional view with internal mechanism omitted" is a lid for housing the chip.
