Abstract
The invention relates to the technical field of virtual reality equipment and provides a safety prompting method for virtual reality equipment. According to the invention, the virtual reality equipment is provided with a microphone to detect and measure the sounds from the outside. The sounds then experience signal conversion into digital signals which are then stored in a storage device. The digital signals are compared with a threshold value. When they reach the threshold value, the wearer is informed and reminded to pay attention to the external environment in case of an accident.
Description
Technical field
The present invention relates to virtual reality device field, more particularly, to a kind of side for virtual reality device safety prompt function
Method.
Background technology
Virtual reality device refers to the hardware product related to technical field of virtual reality, is virtual reality solution
In the hardware device used.Commonly used hardware device in virtual reality at this stage, substantially can be divided into four classes.They are respectively

Row is adjusted.
Further, in the described method for virtual reality device safety prompt function, if exceeding threshold value, will store
Digital signal in device is converted into analogue signal, and is played out external sound by the earphone of virtual reality device, notifies to wear
Wearer.
Further, in the described method for virtual reality device safety prompt function, when notifying wearer, by ear
Machine built-in sound reduces, and external sound is blended on built-in sound and plays out.
Further, in the described method for virtual reality device safety prompt function, when notifying wearer, by ear
Machine built-in sound is closed, and individually plays external sound.
Further, in the described method for virtual reality device safety prompt function, described mike is 2, point
It is not arranged near earphone about virtual reality device.
Compared with prior art, the beneficial effects are mainly as follows: on virtual reality device install mike,
For detecting external sound, and sound is changed into digital signal through signal, and cache in memory, by digital signal with
Threshold value is compared, and when reaching threshold value setting, then notifies wearer, reminds wearer's sensing external environment, it is to avoid unexpected generation.
Brief description
Fig. 1 is the virtual reality device structural representation being provided with mike in one embodiment of the invention；
Fig. 2 is the functional-block diagram in one embodiment of the invention for virtual reality device safety prompt function method.
Specific embodiment
Below in conjunction with schematic diagram, the present invention is carried out for the method for virtual reality device safety prompt function in more detail
Description, which show the preferred embodiments of the present invention it should be appreciated that those skilled in the art can change described here
Invention, and still realize the advantageous effects of the present invention.Therefore, description below is appreciated that for those skilled in the art's
Widely known, and it is not intended as limitation of the present invention.
In order to clear, whole features of practical embodiments are not described.In the following description, it is not described in detail known function
And structure, because they can make the present invention chaotic due to unnecessary details.It will be understood that opening in any practical embodiments
It is necessary to make a large amount of implementation details to realize the specific objective of developer in sending out, such as according to relevant system or relevant business
Limit, another embodiment is changed into by an embodiment.Additionally, it should think that this development is probably complicated and expends
Time, but it is only routine work to those skilled in the art.
Referring to the drawings the present invention more particularly described below by way of example in the following passage.Will according to following explanation and right
Seek book, advantages and features of the invention will become apparent from.It should be noted that, accompanying drawing is all in the form of very simplification and all using non-
Accurately ratio, only in order to purpose that is convenient, lucidly aiding in illustrating the embodiment of the present invention.
In the present embodiment it is proposed that a kind of method for virtual reality device safety prompt function, including step:
At least one mike is installed on virtual reality device, for detecting external sound；
External sound is amplified processing, is converted into digital signal, and caches in memory；
Described digital signal and threshold value are compared, judge whether described digital signal exceeds threshold value；If reaching threshold value,
Then wearer is notified by virtual reality device；If not up to threshold value, wearer need not be notified.
Specifically, refer to Fig. 1, described virtual reality device 10 includes mike 11, earphone 12, eyeshield 13 and wears band
14, wherein, described mike 11 is arranged on earphone 12 adnexa, and in the present embodiment, described mike 11 is two, is respectively mounted
Vicinity in left and right earphone 12.Described mike 11 detects external sound at any time, and described mike 11 is with earphone 12 inside and outside
Isolation, described mike 11 will not introduce the sound that earphone 12 plays out.It is provided with display screen in described eyeshield 13.
Wherein, refer to Fig. 2, left and right mike 11 is amplified respectively through amplifier, and the signal after amplification is through mould
Intend digital converter (adc) and be converted into digital signal, the digital signal handled well is cached in memorizer.The caching of memorizer
Content-length can determine according to the response time of virtual reality device, and the too long of time can affect wearer's environment to external world
The promptness judging, therefore, the usual time can control the length of described digital signal storage within 200 milliseconds.In order to true
Protect left and right mike 11 and accurately can transmit external sound for wearer, it is desirable, therefore, to assure that left and right amplifier is to left and right Mike
The enlargement range of wind 11 is equal.
Digital signal after conversion is compared judgement through comparison module.The principle that threshold values compares is to judge the width of signal
Degree size, if the acoustical signal of the arbitrary microphone channel in left and right exceedes the loudness threshold values of setting, needs to notify wearer, if
Then need not notify less than this loudness threshold values.Described threshold values can be adjusted according to actual environment by wearer.
If threshold values comparison module output result is "Yes", show that demand notifies wearer, the digital signal in caching is again
It is converted into analogue signal, reverts to external sound, and earphone passage switching switch is switched to external sound passage, makes wearer
Hear external sound.
If threshold values comparison module output result is "No", show that now external environmental sounds are not enough to remind wearer,
Can be ignored, earphone passage switches switch keeping closed mode.
When notifying wearer, the built-in sound of earphone 12 is closed, individually play external sound.Additionally, in order to increase
Consumer's Experience it is also possible to external world sound and virtual unit built-in sound mixed, after the order being connected to extraneous prompting, will
Built-in sound reduces, and external sound is blended on built-in sound, such that it is able to avoid virtual unit built-in sound to interrupt.Specifically
, when notifying wearer, earphone 12 built-in sound is reduced, external sound is blended on built-in sound and plays out.
To sum up, in the method for virtual reality device safety prompt function provided in an embodiment of the present invention, in virtual reality
On equipment, mike is installed, for detecting external sound, and sound is changed into digital signal through signal, and be buffered in storage
In device, digital signal is compared with threshold value, when reaching threshold value setting, then notifies wearer, remind wearer that perception is extraneous
Environment, it is to avoid unexpected generation.
Above are only the preferred embodiments of the present invention, the present invention is not played with any restriction effect.Any affiliated
Those skilled in the art, in the range of without departing from technical scheme, to the invention discloses technical scheme and
Technology contents make any type of equivalent or modification etc. and change, and all belong to the content without departing from technical scheme, still
Belong within protection scope of the present invention.
