The warning prompting method, the device and the system provided by the embodiment of the application can solve the problems, realize warning prompting of the device to be positioned and improve user experience.
The embodiment of the application provides a warning prompting method. As shown in fig. 1, the warning prompting method provided by the present embodiment may include the following steps.
In an exemplary embodiment, the signal coverage boundary of the signal transmitter is known, and may be transmitted by the signal transmitter to the device to be located, or may be stored in the device to be located. The device to be positioned may be a head mounted display, a head positioner, a handle, etc.
And 102, acquiring the position relation between the equipment to be positioned and the signal coverage boundary according to the acquired position information of the equipment to be positioned and the signal coverage boundary.
In an exemplary example, the positional relationship may be an angular positional relationship or a coordinate positional relationship.
And 103, comparing the position relation with a preset threshold value to give a warning prompt.
The warning prompting method provided by the embodiment acquires the position information of the equipment to be positioned and the signal coverage boundary of the signal emitter; acquiring the position relation between the equipment to be positioned and the signal coverage boundary according to the acquired position information of the equipment to be positioned and the signal coverage boundary; and comparing the position relation with a preset threshold value to perform warning prompt. The device to be positioned is compared with the preset threshold value according to the position relation between the device to be positioned and the signal coverage boundary, and warning prompt is carried out, so that the situation of inaccurate positioning when the device to be positioned moves out of the positioning range of the positioning signal is avoided, and the user experience is improved.
In one illustrative example, the signal coverage boundary comprises: the boundary of the field angle of the signal emitter.
In an exemplary instance, obtaining the position relationship between the device to be positioned and the signal coverage boundary according to the obtained position information of the device to be positioned and the signal coverage boundary includes:
acquiring an included angle between the equipment to be positioned and the normal of the signal transmitter according to the position information;
and comparing the included angle with the boundary of the field angle to acquire the position relation between the equipment to be positioned and the signal coverage boundary.
In an exemplary example, assuming that a Field Of View (FOV) when the signal emitter is horizontally placed is α, acquiring a signal coverage boundary Of the signal emitter includes acquiring the signal coverage boundary when the signal emitter is horizontally placed, a device to be positioned falls in any one area Of a space, calculating an included angle between the device to be positioned and a normal Of a front panel Of the signal emitter to be recorded as β, and determining whether the device to be positioned is located within the signal coverage range Of the signal emitter according to a relationship between β and α, thereby performing warning prompt. The specific judgment method comprises the following steps:
if the beta is less than alpha/2, the equipment to be positioned is determined to be positioned in the signal coverage range of the signal transmitter, the equipment to be positioned can work well, and the positioning precision is also guaranteed sufficiently.
If the beta is larger than or equal to the alpha/2, the equipment to be positioned is determined to be positioned outside the signal coverage range of the signal transmitter, and the equipment to be positioned may not obtain a good positioning effect.
In an exemplary example, assuming that the signal emitter is horizontally placed and the FOV is α, the device to be positioned includes a device a to be positioned and a device B to be positioned, an included angle between the device a to be positioned and a normal of a front panel of the signal emitter is denoted as β 1, an included angle between the device B to be positioned and a normal of a front panel of the signal emitter is denoted as β 2, and a schematic diagram of relative positions of the signal emitter and the device to be positioned is shown in fig. 2.
Because beta 1 is more than alpha/2, the equipment A to be positioned is positioned outside the signal coverage range, and the positioning performance is reduced; because beta 2< alpha/2, the equipment B to be positioned is in the signal coverage range, and the positioning performance is good.
In an illustrative example, the alert prompt includes at least one of: vibration mode and sound mode.
In an exemplary embodiment, when the device for performing the alert prompt includes a head-mounted display, the alert prompt further includes: and (4) a picture mode.
In one illustrative example, the screen mode includes at least one of: brightness displayed on the head mounted display, a guide icon displayed on the head mounted display, a warning indication displayed on the head mounted display.
In one illustrative example, a warning prompt is made if a positional relationship between a device to be located and a signal coverage boundary of a signal transmitter and a preset threshold satisfy a preset relationship. The reminding can be performed on the equipment to be positioned or on the signal transmitter, specifically, the warning prompt can be performed through the head-mounted display to remind a user of paying attention to the boundary, and the reminding can be realized by methods of darkening a picture on the head-mounted display, displaying a guide icon on the picture of the head-mounted display, displaying a warning mark on the picture of the head-mounted display and the like; or the alarm can be given by means of vibration or buzzing of equipment such as a head-mounted display, a handle, a locator, a signal transmitter and the like so as to remind the user of paying attention to the boundary. Or a set of vibration, voice, and image display multiple reminding modes, for example, when it is found that the device to be positioned is about to exceed the signal boundary, the interactive device such as the head-mounted display or the handle vibrates, and the microphone on the head-mounted display or the signal transmitter sends out a voice alarm prompt: "will go beyond the positioning boundary and please move forward", optionally while displaying a guide icon towards the high signal strength area on the screen of the head mounted display, e.g. a previous indicator arrow appears, indicating that the user moves in the direction of the arrow. And when the position relation between the equipment to be positioned and the signal coverage boundary of the signal transmitter and the preset threshold value do not meet the preset relation, the reminding disappears.
In an exemplary embodiment, the number of the preset thresholds is M; the warning prompting modes of the equipment to be positioned are M types, wherein the ith preset threshold is smaller than the (i + 1) th preset threshold, and i is 1 or 2 … M-1.
In one illustrative example, comparing the position relationship with a preset threshold value to perform a warning prompt includes:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, warning prompting is carried out in an ith warning prompting mode;
and when the position relation is larger than the Mth preset threshold value, carrying out warning prompt in the Mth warning prompt mode.
In an exemplary embodiment, the warning indication mode may be a vibration mode in which M kinds of vibration intensities (for example, vibration amplitudes and vibration frequencies) are sequentially increased. For example, the warning indication mode may be M vibration modes in which the vibration amplitudes are sequentially increased. When the warning prompt mode is a vibration mode in which M vibration amplitudes are sequentially enhanced, comparing the position relation with a preset threshold value to perform warning prompt, and the method comprises the following steps:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, warning prompt is carried out according to the ith vibration amplitude;
and when the position relation is larger than the Mth preset threshold value, warning prompt is carried out according to the Mth vibration amplitude.
In an exemplary example, the warning prompting manner may also be M vibration manners in which vibration frequencies sequentially increase, for example, when M is equal to 3, when the position relationship between the device to be positioned and the signal coverage boundary is greater than a first threshold and smaller than a second threshold (assuming that the first threshold is smaller than the second threshold and the second threshold is smaller than a third threshold), the warning prompting is performed only at a lower vibration frequency, when the position relationship between the device to be positioned and the signal coverage boundary is greater than the second threshold and smaller than the third threshold, the warning prompting is performed at an increased vibration frequency, and when the position relationship between the device to be positioned and the signal coverage boundary is greater than the third threshold, the warning prompting is performed at a maximum vibration frequency.
In an exemplary example, the warning prompting manner may also be a vibration manner in which the vibration amplitude and the vibration frequency are simultaneously increased, that is, M vibration manners in which the vibration amplitude and the vibration frequency are sequentially increased, for example, M is 3, when the position relationship between the device to be positioned and the signal coverage boundary is greater than a first threshold and smaller than a second threshold (assuming that the first threshold is smaller than the second threshold and the second threshold is smaller than a third threshold), the warning prompting is performed only with a weaker vibration amplitude and a lower vibration frequency, when the position relationship between the device to be positioned and the signal coverage boundary is greater than the second threshold and smaller than the third threshold, the warning prompting is performed with an enhanced vibration amplitude and an increased vibration frequency, and when the position relationship between the device to be positioned and the signal coverage boundary is greater than the third threshold, the warning prompting is performed with a strongest vibration amplitude and a maximum vibration frequency.
In an exemplary embodiment, the alert prompt may be in M sound modes with sequentially increasing volume intensity. When the warning prompt mode is a sound mode that the volume intensity of M types increases in sequence, comparing the position relation with a preset threshold value to perform warning prompt, and the method comprises the following steps:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, carrying out warning prompt by using the ith volume intensity;
and when the position relation is larger than the Mth preset threshold value, carrying out warning prompt by the Mth volume intensity.
In an exemplary example, for example, when the position relationship between the device to be located and the signal coverage boundary is greater than the first threshold and less than the second threshold (assuming that the first threshold is less than the second threshold and the second threshold is less than the third threshold), the warning is only performed at a weaker volume intensity, when the position relationship between the device to be located and the signal coverage boundary is greater than the second threshold and less than the third threshold, the warning is performed at an enhanced volume intensity, and when the position relationship between the device to be located and the signal coverage boundary is greater than the third threshold, the warning is performed at a maximum volume intensity.
In an exemplary embodiment, the alert prompting manner may also be M sequentially highlighted screen manners. For example, the warning indication mode may be a screen mode in which the coverage area formed by the signal coverage boundary is displayed with a reduced brightness degree or all images are displayed with M kinds of brightness reduced in sequence. When the warning indication mode is a mode of displaying a coverage area formed by the signal coverage boundary or all images by the sequentially reduced brightness degrees, comparing the position relation with a preset threshold value to perform warning indication, and the method comprises the following steps:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, displaying a coverage range formed by the signal coverage boundary or all images through the ith brightness degree to give a warning prompt;
and when the position relation is larger than the Mth preset threshold value, displaying a coverage range formed by the signal coverage boundary or all images through the Mth brightness degree to give a warning prompt.
In an exemplary instance, when the position relationship between the device to be located and the signal coverage boundary is greater than a first threshold value and less than a second threshold value (assuming that the first threshold value is less than the second threshold value, and the second threshold value is less than the third threshold value), the coverage area formed by the signal coverage boundary or all images are displayed only with a slightly low brightness degree for warning indication, when the position relation between the equipment to be positioned and the signal coverage boundary is larger than the second threshold value and smaller than the third threshold value, the coverage area formed by the signal coverage boundary or all images are displayed with a lower brightness degree to carry out warning prompt, when the position relation of the equipment to be positioned and the signal coverage boundary is more than a third threshold value, the warning prompt is made by stopping the display of the coverage area or all images formed by the signal coverage boundaries to a minimum brightness or directly.
In an exemplary embodiment, the warning prompting manner may also be to display M guidance icons which are gradually dense or conspicuous towards the high signal strength area. When the warning prompting mode is to display M guiding icons which are gradually dense or conspicuous towards the high signal intensity area, comparing the position relation with a preset threshold value to prompt a warning, and the method comprises the following steps:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, displaying the ith guide icon facing the high signal intensity area to give a warning prompt;
and when the position relation is larger than the Mth preset threshold value, displaying the Mth guide icon facing to the high signal intensity area to give a warning prompt.
In an exemplary example, for example, when the position relationship between the device to be located and the signal coverage boundary is greater than the first threshold and less than the second threshold (assuming that the first threshold is less than the second threshold and the second threshold is less than the third threshold), the warning is only given by sparse or ordinary guidance icons facing the high signal strength area, when the position relationship between the device to be located and the signal coverage boundary is greater than the second threshold and less than the third threshold, the warning is given by more dense or conspicuous guidance icons facing the high signal strength area, and when the position relationship between the device to be located and the signal coverage boundary is greater than the third threshold, the warning is given by most dense or conspicuous guidance icons facing the high signal strength area.
In an exemplary embodiment, the warning indication manner may be to display M kinds of sequentially highlighted warning marks. When the warning prompting mode is to display M kinds of sequentially striking warning marks, the comparison is carried out according to the position relation and a preset threshold value so as to carry out warning prompting, and the method comprises the following steps:
when the position relation is larger than the ith preset threshold and smaller than the (i + 1) th preset threshold, displaying the (i) th striking warning mark to give warning prompt;
and when the position relation is larger than the Mth preset threshold value, displaying the Mth striking warning mark to perform warning prompt.
In an exemplary example, for example, when the position relationship between the device to be positioned and the signal coverage boundary is greater than a first threshold and less than a second threshold (assuming that the first threshold is less than the second threshold and the second threshold is less than a third threshold), the warning is only given by a normal warning indicator, when the position relationship between the device to be positioned and the signal coverage boundary is greater than the second threshold and less than the third threshold, the warning is given by an emphasized warning indicator, and when the position relationship between the device to be positioned and the signal coverage boundary is greater than the third threshold, the warning is given by an exaggerated warning indicator.
In an exemplary embodiment, the alert prompt may also be a combination of vibration, sound and visual, for example, when the position relationship between the device to be positioned and the signal coverage boundary is greater than the first threshold value and smaller than the second threshold value (assuming that the first threshold value is smaller than the second threshold value, and the second threshold value is smaller than the third threshold value), the warning prompt is only carried out in the modes of slight vibration or low-decibel voice or unobtrusive arrow display information and the like, when the boundary distance between the equipment to be positioned and the signal coverage is larger than the second threshold value and smaller than the third threshold value, then the warning prompt is carried out in the modes of increasing vibration or large decibel voice or prominent display information and the like, when the boundary distance between the equipment to be positioned and the signal coverage is greater than a third threshold value, the warning indication is performed by stopping or weakening the screen display of the head-mounted display or highlighting the guide icon.
In one illustrative example, the preset threshold is an angle when the positional relationship between the device to be located and the signal coverage boundary is an angular positional relationship. Assuming that M is 3, the first threshold is-15 °, the second threshold is-5 °, and the third threshold is 10 °, referring to fig. 2, when the difference between the angles β and α is within-15 ° to-5 °, a warning is provided only in the form of a slight vibration, a low decibel voice, or an unobtrusive arrow display message; when the difference value of the included angle beta and the included angle alpha is between-5 degrees and 10 degrees, warning prompt is carried out in the modes of increasing vibration or large decibel voice or obvious display information and the like; and when the difference value of the included angles beta and alpha is larger than 10 degrees, stopping the picture display of the head-mounted display.
In one illustrative example, acquiring a signal coverage boundary of a signal transmitter further comprises:
acquiring the inclined placement angle of the signal emitter;
when the inclined placement angle is larger than the preset inclined angle, warning prompt is carried out.
In an exemplary embodiment, the tilt angle of the signal transmitter may be obtained by an Inertial Measurement Unit (IMU) built into the signal generator.
In an exemplary example, acquiring the signal coverage boundary of the signal transmitter includes acquiring the signal coverage boundary when the signal transmitter is obliquely placed, assuming that the signal transmitter is obliquely placed and the FOV is α, the device to be positioned includes a device a 'to be positioned and a device B' to be positioned, an included angle between the device a 'to be positioned and a normal line of a front panel of the signal transmitter is denoted as β 3, an included angle between the device B' to be positioned and a normal line of the front panel of the signal transmitter is denoted as β 4, and a schematic diagram of relative positions of the signal transmitter and the device to be positioned is shown in fig. 3.
The device A to be positioned is out of the signal coverage range and the out-of-range is too large, so that the positioning can not be carried out; because beta 4< alpha/2, the device B to be positioned is out of the signal coverage range, and the positioning performance is reduced.
The downward tilt of the signal transmitter results in the device to be positioned being easier at the upper boundary of the signal coverage, while the lower boundary of the signal coverage can only reach the horizon at the lowest, so the lower boundary is wasted and unusable, resulting in a smaller FOV for practical use.
In an exemplary embodiment, the alert prompt may be made in a different manner as the angle of tilt placement of the signal emitter increases, as may the signal coverage boundary prompt.
In an exemplary example, the number of the preset inclination angles is N; the warning prompting modes of the equipment to be positioned are N, wherein the jth preset inclination angle is smaller than the jth +1 preset inclination angle, and j is 1 … N-1;
