Abstract

A head-mounted display device includes one or more lenses and a display configured to provide visual data through the one or more lenses. The head-mounted display device also includes a direct-current (DC) motor mechanically coupled to the display, and the DC motor is configured to move the display along an axis by rotating a rotatable component of the DC motor. The head-mounted display device further includes: position sensor(s) configured to determine a position of the display, and electronic controller(s) in communication with the position sensor(s). The electronic controller(s) are configured to: (i) receive, from the position sensor(s), the determined position of the display as a first position of the display, (ii) receive information identifying a second position of the display, and (iii) generate electrical signal(s) that cause the DC motor to move the display from the first position to the second position along the axis.

receive information identifying a second position of the second display and/or the second set of one or more lenses;
and
generate one or more electrical signals that cause the second DC motor to move the second display and/or the second set of one or more lenses from the first position of the second display and/or the second set of one or more lenses to the second position of the second display and/or the second set of one or more lenses along the second axis.

16 more elements

A method of moving displays in a head-mounted display device, the method comprising:

at a first set of one or more electronic controllers of a head-mounted display device:
receiving, from a first set of one or more position sensors of the head-mounted display device, a first position of a first display and/or a first set of one or more lenses of the head-mounted display device, the first position being a position of the first display and/or the first set of one or more lenses determined by the first set of one or more position sensors;
receiving information identifying a second position of the first display and/or the first set of one or more lenses;
and
generating one or more electrical signals that cause a first DC motor to move the first display and/or the first set of one or more lenses from the first position to the second position along a first axis;
and
at a second set of one or more electronic controllers of a head-mounted display device:
receiving, from a second set of one or more position sensors of the head-mounted display device, a third position of a second display and/or a second set of one or more lenses of the head-mounted display device, the third position being a position of the second display and/or the first set of one or more lenses determined by the second set of one or more position sensors;
receiving information identifying a fourth position of the second display and/or the second set of one or more lenses;
and
generating one or more electrical signals that cause a second DC motor to move the second display and/or the second set of one or more lenses from the third position to the fourth position along a second axis.

8 more elements

receiving information identifying a second position of the first display and/or the first set of one or more lenses;
and
generating one or more electrical signals that cause a first DC motor to move the first display and/or the first set of one or more lenses from the first position to the second position along a first axis;
and
the second set of one or more electronic controllers comprises:
a second set of one or more processors;
and
second memory storing a second set of one or more programs for execution by the second set of one or more processors, the second set of one or more programs including instructions for:
receiving, from a second set of one or more position sensors of the head-mounted display device, a third position of a second display and/or a second set of one or more lenses of the head-mounted display device, the third position being a position of the second display and/or the second set of one or more lenses determined by the first set of one or more position sensors;
