Abstract
The present disclosure relates to a wearable display device. According to an exemplary embodiment, the wearable display device includes: a display unit configured to display an image; a wearing means configured to fix the display unit on a body part; a plurality of sensors positioned on one surface of the wearing means and configured to contact a measuring target to measure a bio-signal from the measuring target; and a wearing means adjustment section included in the display unit and configured to adjust a length of the wearing means contacting the measuring target of the wearing means by using the bio-signal.
Claims8
A wearable display device comprising:
- a display unit configured to display an image;
- a wearing band configured to fix the display unit on a body part;
- a plurality of sensors positioned on one surface of the wearing band and configured to contact a measuring target to measure at least one bio-signal from the measuring target;
- a wearing band adjustment section included in the display unit and configured to adjust a length of the wearing band contacting the measuring target of the wearing band by using the at least one bio-signal,
- a memory configured to store at least one information which directly or indirectly expresses the at least one bio-signal, and
- a certification section configured to derive at least one of user certification information on the basis of the at least one bio-signal and store the at least one of user certification information in the memory,
- wherein at least some of the plurality of sensors are configured to sense a first bio-signal generated by a user gesture,
- the wearing band adjustment section compares the first bio-signal with a wear reference value stored in the memory to determine the length of the wearing band,
- at least some of the plurality of sensors are configured to measure a second bio-signal from the measuring target,
- the certification section is configured to derive the at least one of user certification information on the basis of the second bio-signal, and
- the user certification information includes at least one selected from a wrist thickness and a wrist length of the measuring target when the wearable display device is worn on a wrist of the measuring target.
A method for controlling a wearable display device including a display unit, a wearing band fixing the display unit on a body part, a plurality of sensors contacting a measuring target and measuring at least one bio-signal from the measuring target, and a motor driven for length adjustment of the wearing band, the method comprising:
- measuring a first bio-signal by at least some of the plurality of sensors, the first bio-signal generated in response to the wearable display device being worn on the body part;
- adjusting a length of the wearing band contacting the measuring target of the wearing band on the basis of the first bio-signal;
- measuring a second bio-signal from the measuring target by at least some of the plurality of sensors;
- deriving at least one of a user certification information on the basis of the second bio-signal;
- storing the at least one of user certification information in a memory;
- using the user certification information to certify a user corresponding to the user certification information;
- when the user is certified, providing a user interface according to a setting information of the display device for the user with reference to the memory, and
- when the user is not certified, controlling the display unit so as to end a device operation in the display device;
- wherein the step of adjusting the length of the wearing band includes:
- comparing the first bio-signal and a predetermined wear reference value stored in the memory to determine the length of the wearing band;
- generating a control signal including a signal on the length of the wearing band and transmitting the control signal to the motor by the display unit;
- and
- driving the motor to adjust the length of the wearing band on the basis of the control signal, and
- wherein the user certification information includes at least one selected from a wrist thickness and a wrist length information of the measuring target when the wearable display device is worn on a wrist of the measuring target.
