Specific embodiment
For objects, features and advantages of the present invention can be clearer and more comprehensible, specific embodiments of the present invention are cited below particularly out,
And cooperate Figure of description, it is described in detail below.
Some vocabulary is used in the specification and claims to censure specific element.Those skilled in the art answer
It is understood that hardware manufacturer may call the same element with different nouns.This specification and claims not with
The difference of title is as the mode for distinguishing element, but with the difference of element functionally as the criterion of differentiation.Logical
The "comprising" and one word of " comprising " of piece specification and claim mentioned in are open term, therefore should be construed to " packet
Contain but be not limited to "." substantially " word then refers to that within an acceptable error range, those skilled in the art can be certain
The technical problem is solved in error range, reaches the basic technical effect.In addition, " coupling " word is in the present specification
Include any direct and indirect means of electrical connection.Therefore, if it is described herein that a first device is coupled to a second device, then
The second device can be directly electrically connected to by representing the first device, or indirectly electrical via other devices or connection means
It is connected to the second device.
Fig. 1 be show head-mounted display described in an embodiment according to the present invention (Head MountedDisplay,
HMD) 100 schematic diagram.Head-mounted display 100 can apply virtual reality (VirtualReality, VR) technology, and can be by one
User dresses.As shown in Figure 1, head-mounted display 100 includes a device noumenon (Device Body) 110 and multiple
Light emitting diode (Light-EmittingDiode, LED) 121,122,123.Light emitting diode 121,122,123 is to be set to
In device noumenon 110, wherein both arbitrary neighborhoods of light emitting diode 121,122,123 (such as: light emitting diode 121,122)
With different flicker frequencies.For example, the flicker frequency of light emitting diode 121 can be 100Hz, and with it is adjacent another
The flicker frequency of light emitting diode 122 can be 200Hz.On the contrary, all separate with both light emitting diodes 121,122 luminous two
The flicker frequency of pole pipe 123 is then unrestricted, can be 100Hz, 200Hz, 400Hz or any other frequency.In some realities
It applies in example, a space D 1 of so-called " adjacent pairs of light emitting diode " (such as: light emitting diode 121,122) must be less than 1
One both set a distance (such as: 2 centimeters or 3 centimeters).Mutually, whereas if space D 1 is greater than the first both set a distance, then this two are judged
Light emitting diode is not adjacent to each other.It is not depicted in Fig. 1 although must be noted that, actually device noumenon 110 can also wrap

Formula display 100 may include less or more light emitting diode, such as: any times of 2,4,5,6 or 4
Number.
In general, a motion capture system (Motion Capture System) can according to light emitting diode 121,
122, the device noumenon 110 that illuminated message provided by 123 carrys out head-mounted display 100 is positioned (Position).?
In traditional design, because the flicker frequency of all light emitting diodes 121,122,123 is set as identical, it is easy to cause dynamic
Make capture system and mixes up adjacent light emitting diode (for example, it may be possible to which it is same for treating as adjacent light emitting diode 121,122
Light emitting source), this will reduce the precision of positioning, and the user for wearing head-mounted display 100 is caused to generate spinning sensation.In order to
Overcome the predicament that the prior art is faced, the invention proposes by both arbitrary neighborhoods of light emitting diode 121,122,123 all
It is set as the novel designs of different flicker frequencies, motion capture system can be increased for each light emitting diode 121,122,123
Discrimination, and help to improve virtual reality whole degree of verisimilitude and reduce user wear head-mounted display 100 when institute
The sense of discomfort faced.
The light emitting diode 121 it is to be understood that shape of head-mounted display 100, type, and thereon, 122,
123 quantity, configuration mode are not particularly limited in the present invention.The following example will introduce each of head-mounted display 100
Kind different configuration (Configuration), content, which is only for example, makes reader it can be readily appreciated that the right being not intended to limit the invention
It is required that.
Fig. 2A is the expanded view for showing head-mounted display 200 described in an embodiment according to the present invention.Fig. 2 B is display
The perspective view of head-mounted display 200 described in an embodiment according to the present invention.Scheme please also refer to 2A, 2B.In 2A, 2B
In the embodiment of figure, a device noumenon 210 of head-mounted display 200 includes before the upper cover 211, one in Different Plane
Lid 212, a left cap 213 and a right cap 214, wherein have multiple light emitting diodes 221,222 ..., 234 be it is uniform or
It is non-uniformly distributed in upper cover 211, front cover 212, left cap 213 and right cap 214.In some embodiments, upper cover
211, an at least light emitting diode is all configured in each of front cover 212, left cap 213 and right cap 214.Citing and
Speech, three light emitting diodes 221,222,223 may be disposed in upper cover 211, five light emitting diodes 224,225,226,227,
228 may be disposed on front cover 212, and three light emitting diodes 229,230,231 may be disposed in left cap 213, and three shine
Diode 232,233,234 may be disposed in right cap 214.
As previously mentioned, light emitting diode 221,222 ..., both 234 arbitrary neighborhoods should have different flicker frequencies.
In some embodiments, regardless of whether it is in the same plane, if light emitting diode 221,222 ..., 234 it is both any
The spacing of (such as: light emitting diode 221,224) both set a distance (such as: 2 centimeters or 3 centimeters) less than first, that is, can be considered
It is adjacent, the flicker frequency for having different should be set as.On the contrary, not adjacent light emitting diode (such as: light emitting diode 221,
233), its spacing is if more than the first both set a distance, then not limited, can have identical or different flicker frequency.At other
In embodiment, head-mounted display 200 may include less or more light emitting diode, the distribution in device noumenon 210
Mode can be also adjusted according to different demands.
