  • Such a compact design may be required for a head-mounted device since a bulky and heavy head-mounted device would not only cause inconvenience during usage but also brings health risks, especially aggravating neck pains. Consequently, a lot of head-mounted devices try to dispose every component as close as possible to the user’s head, such that the users would experience less discomforts due to the imbalanced additional weight when moving or turning their heads.
