Abstract
Disclosed are head-mounted personal multimedia systems and visual assistance devices thereof, which are featured with a diopter adjustment unit to configurably provide various diopters for the user's eye(s) to watch. In order to watch clearly the picture displayed by a fixed-range display surface, the user's eyes can perform physiological accommodation movements in response to the diopters dynamically configured by the diopter adjustment unit, so that the eye fatigue could be prevented.
Claims15
A head-mounted personal multimedia system, comprising:
- a display unit, providing a fixed display surface to display an image to a user;
- a gaze detection unit, detecting a gaze direction of at least one eye of the user towards the image;
- a diopter adjustment unit, located between the fixed display surface and the eye, configurably providing at least one first diopter or a second diopter to the eye for viewing, wherein the eye is capable of correspondingly performing physiological accommodation movements in response to the first diopter or the second diopter provided to clearly view a region corresponding to the gaze direction in the image;
- and
- a control unit, signally connected to the diopter adjustment unit and the gaze detection unit, controlling the diopter adjustment unit according to the gaze direction detected by the gaze detection unit to provide the first diopter or the second diopter.
A visual assistance device, detachably installed in a head-mounted personal multimedia system, the head-mounted personal multimedia system comprising a display unit to provide a fixed display surface for displaying an image to a user, the visual assistance device comprising:
- a gaze detection unit, detecting a gaze direction of at least one eye of the user towards the image;
- a diopter adjustment unit, located between the fixed display surface and the eye, configurably providing at least one first diopter or a second diopter to the eye for viewing, wherein the eye is capable of correspondingly performing physiological accommodation movements in response to the first diopter or the second diopter provided to clearly view a region corresponding to the gaze direction in the image;
- and
- a control unit, signally connected to the diopter adjustment unit and the gaze detection unit, controlling the diopter adjustment unit according to the gaze direction detected by the gaze detection unit to provide the first diopter or the second diopter.
A visual assistance device, detachably installed in a head-mounted personal multimedia system, the head-mounted personal multimedia system comprising a display unit to provide a fixed display surface for displaying an image to a user, and a gaze detection unit for detecting a gaze direction of at least one eye of the user towards the image, the visual assistance device comprising:
- a diopter adjustment unit, located between the fixed display surface and the eye, configurably providing at least one first diopter or a second diopter to the eye for viewing, wherein the eye is capable of correspondingly performing physiological accommodation movements in response to the first diopter or the second diopter provided to clearly view a region corresponding to the gaze direction in the image;
- and
- a control unit, signally connected to the diopter adjustment unit and the gaze detection unit, controlling the diopter adjustment unit according to the gaze direction detected by the gaze detection unit to provide the first diopter or the second diopter.
