Development of a head-up displayed diving computer capability for full face masks

摘要

Professional clivers often dive in conditions of very low visibility. In such situations, a head-up display has many advantages as water clarity does not affect the ability to see the display. In addition, a head-up display allows divers to continuously monitor all relevant dive data without interrupting their work. The present paper details the development of a new diving computer that has been designed with a head-up display and integrated into an AGA type full face mask. The device includes a full colour display, depth sensor, tilt-compensated compass and a tank pressure sensor. Typical dive relevant data (depth, time, decompression obligations) including tank pressure and heading are displayed and stored in the internal flash memory.
