In electronic installation 10, integrate location and direction-pointing function in order to realize technology of the present invention, also be provided with a location module 16, in the electronic installation 10 and point to module 18, and point to interface 20, a height indicating module 22, a height and indicate interface 24, a landform module 26, a wake module 28, a memory module 30 and an operation and control interface 32.In preferred embodiment of the present invention, can utilize GPS (GPS) to locate, so can be provided with corresponding antenna, relevant signal processing circuit and decoding scheme in the locating module 16, be used for each satellite is launched in the receiving world locational system wireless signal and being handled, to detect the current location of electronic installation 10 itself in real time, similarly be the coordinate of longitude and latitude, and height (vertical height from the face of land).So, when the user carries electronic installation 10 and moves, when locating module 16 just can detect the user on the way and moves by way of everywhere coordinate and height.
Coordinate that is provided according to locating module 16 and height, wake module 28 can realize arrival notice or the function of waking up, points to that module 18,22 of indicating modules of height can be used for respectively realizing pointing to and the function of height indication; And memory module 30 promptly is used for record (storage) and wakes up/or location/direction/required relevant information of using when height is indicated.The number of times of topographic relief on the way when 26 of landform modules can be managed a terrain data and moved to represent the user.In preferred embodiment of the present invention, pointing to interface 20, just indicate interface 24 can be graphical display interface, points out the user with intuitive graphic picture.28 of operating and controlling interfaces can receive user's the instruction of controlling, to control the running of (comprise and point to module 18, height indicating module 22, medium access module 12, playing module 14, wake module 28 and landform module 26 etc.) of other each module.
Utilize and point to module 18, height indicating module 22 and wake module 28, conformability of the present invention location and direction mechanism can provide several functionalities or pattern.At first be arrival notice and the function of waking up.When the user will be when move a destination, the user can start wake module 28 via operating and controlling interface 32 earlier, and with the coordinate of destination and highly input to electronic installation 10, by memory module 30 record in addition.Then, during the user moved, whether wake module 28 just can make pointed to the current coordinate of module 18 lasting comparison users near the destination coordinate, and makes height indicating module 22 whether compare users' current height near the destination height.If point to coordinate that module 18 or height indicating module 22 find that users are current and highly near the coordinate and the height (just the difference of two coordinates and height is less than default value) of destination, wake module 28 just can be pointed out the user, and allowing the user know will reach the destination.
In one embodiment of the invention, wake module 28 can utilize the function of playing module 14 to point out the user; For example, wake module 28 can be mixed to the multimedia signal with the prompting of presetting or the image that wakes up, sound or audio-visual signal, allows playing module 14 that both are played back in the lump; So, when the user when watching or listen to the multimedia signal, also can watch in the lump or uppick arrival notice or the prompting that wakes up.Perhaps, wake module 28 also can temporarily stop the broadcast of the normal multimedia signal of playing module 14 when the prompting user, change specific prompting image, sound or the audio-visual user of prompting of broadcast into and reach the destination.When the user did not use playing module 14 playing videos, sound or audio-visual multimedia, wake module 28 also can start playing module 14 automatically in the time will pointing out the user, made playing module 14 play prompting image, the sound or audio-visual of arrival notice.In addition, the present invention also can select prompting image, the sound or audio-visual of arrival notice in conjunction with the function of medium access module 12; For example, when wake module 28 will be pointed out the user, multimedia image, sound or the audio/video file that can make medium access module 12 change the access user into to specify in advance.For instance, electronic installation 10 can be a walkman, and it can play 10 sections different music (similarly being 10 first songs) one by one, and the user can select wherein one section music to be used as the prompting of arrival notice; When wake module 28 will be pointed out the user, just can make medium access module 12 skip to this section music, change into and play the prompting that this section music is used as arrival notice.In addition, wake module 28 itself also can have special-purpose visual interface (for example being a warning lamp) or other man-machine interface (similarly being the electromagnetic shaker that can send vibrations), with prompting user near the destination time.
Please refer to Fig. 2 (and in the lump with reference to figure 1); Flow process 100 among Fig. 2 is that electronic installation of the present invention 10 is realized arrival notices or the process when waking up.Flow process 100 among Fig. 2 has the following step:
Step 102: the function that the user can start arrival notice or wake up via operating and controlling interface 32 (Fig. 1) earlier before beginning is moved toward the destination, and the coordinate of input destination and height.
Step 104: the user carries electronic installation 10 beginnings and moves toward the destination; During the user moved, locating module 16 can continue to detect user's's (electronic installation 10) itself current coordinate and height.
Step 106: under the management of wake module 28, point to module 18 with height indicating module 22 sustainable more current coordinates and highly whether near destination coordinate and height; According to comparative result, wake module 28 can judge that the user is whether near destination (that is to say that whether the difference of current coordinate and height and destination coordinate and height is less than default value); If then flow process 100 can proceed to step 108; If not, then get back to step 104, continue to check current coordinate and highly whether near destination coordinate and height.
Step 108: the prompting of sending arrival notice or waking up allows the user know that the destination is near (or having arrived at).
When realization flow 100, the present invention can be simultaneously at coordinate with highly judge whether to reach the destination, also can be only one of them judges whether to reach the destination according to coordinate or height.For example, when carrying out step 102, the user can only import the destination height, and whether step 104,106 can only compare the current position height of user near the destination height; If can in step 108, send prompting.For example, when mountain-climbing, when the user had climbed to high height, the user may need to take special moving to be incubated or to prevent high mountain disease or the like; Under this used, the user just can utilize the present invention to learn in function described herein whether its position height has reached a certain default object height.In addition, the user also can write down the default destination of array in advance in memory module 30, select a destination when reality is mobile again.For instance, the user can be in memory module 30 with the coordinate of user's dwelling and office and be recorded as a destination coordinate highly respectively and height.When the user will be when office be gone in the dwelling, can select office is the destination, and electronic installation 10 will be pointed out the user when arriving at office.Relatively, when the user will return the dwelling by office, can select the dwelling as the destination, and electronic installation 10 will be pointed out the user when returning to the user dwelling.
Generally speaking, arrival notice of the present invention or arousal function can be practically just pointed out the user the user during near the destination, can avoid the user to miss the destination and do not know.For example, when the user took public transportation vehicle, regular meeting was engaged in other activity (similarly be read or close the eyes for rest) and misses the destination easily; If estimate the arrival time and timing wake-up, may just point out the user too early or excessively evening because of the error of estimated time.If utilize technology of the present invention, just can be practically correctly point out the user during near (arriving at) destination the user, allow the user be unlikely and miss the destination.
Except arrival notice or the function waken up, the present invention also can provide the direction-pointing function of recalling in return path.Please once again with reference to figure 1.Electronic installation 10 among Fig. 1 can operate on one along a journey pattern and a return pattern.When the user begins when mobile (for example be begin mountain-climbing or when cross-country), electronic installation 10 is operated on along the journey pattern.Under this pattern, locating module 16 can detect the coordinate and the height of former starting point; During the user moved, locating module 16 also can detect the coordinate by way of everywhere on the way, and memory module 30 just can be a reference coordinate and height with at least one coordinate record wherein.For example, the user can be via being a reference coordinate and height to the control of operating and controlling interface 32 and with the coordinate and the altitude record of starting point when setting out.During the user moves, when the user through noticeable intermediate point (similarly being cross road branch point, the turning in path or the like), also can trigger operating and controlling interface 32 and be corresponding reference coordinate and height the coordinate and the altitude record of these intermediate points.
When the user will recall the path (for example be not to use person lost and when wanting to turn back back former starting point), just can make electronic installation 10 operate on the return pattern via operating and controlling interface 32.Under this pattern, point to module 18 a meetings coordinate that the user is current and a reference coordinate in the memory module 30 and compare, and produce the sensing signal of a correspondence according to difference between the two.Simultaneously, the coordinate height that height indicating module 22 also can be current with the user and the height of this reference coordinate compare, to produce the height indicating signal of a correspondence according to difference between the two.Just can give the user and point to interface 20, allow the user learn the direction (similarly be directions such as the four corners of the world) of reference coordinate with respect to user itself with pointing to the signal prompting; Height indicates 24 interfaces the prompting of height indicating signal can be given the user, allows the user learn the height of the height of reference coordinate with respect to user itself.For instance, when pointing to module 18 the time, if the longitude of current coordinate greater than the longitude of reference coordinate, then represents reference coordinate in the west of user position (if less than then being east) with current coordinate and reference coordinate comparison; If the latitude of current coordinate greater than the latitude of reference coordinate, then represents reference coordinate in the south of user position (otherwise then being the north).Point to module 18 and can in pointing to signal, reflect the east/west and south/north of reference coordinate with respect to the user position, point to interface 20 and just relative direction can be shown and the user, the prompting user will be toward which side to moving the position that could arrive the reference coordinate place.In like manner, when height indicating module 22 is compared the height of the height of the current coordinate of user and reference coordinate, if the height of reference coordinate is greater than the height of the current coordinate of user, height indicating module 22 just can make height indicate interface 24 to indicate users' move up (for example being to hoist to climb).
According to pointing to interface 20 and the indication of just indicating interface 24, the user just can move towards this reference coordinate, recalls to be back to this reference coordinate.More particularly, when the return pattern, sensing module 18 of the present invention or height indicating module 22 can further operate on a director pattern and a track subpattern.Under the director pattern, point to module 18 or height indicating module 22 and can directly be back to former starting point with the indication user directly with the reference coordinate and the height of former starting point as comparison.Under the track subpattern, point to module 18 or height indicating module 22 and can follow each intermediate point with the indication user and back move the former starting point of finally turning back back successively with the reference coordinate of each intermediate point and highly as the standard of comparison.
Please refer to Fig. 3 (and in the lump with reference to figure 1); Flow process 200 among Fig. 3 is each step that electronic installation 10 of the present invention (Fig. 1) is carried out when return path back track function is provided.The following step is arranged in the flow process 200:
Step 202: the user carries electronic installation 10 and begins to leave.The user can trigger electronic installations 10 via operating and controlling interface 32 in starting point, and electronic installation 10 is operated on along the journey pattern, and to make memory module 30 be a reference coordinate and height with the coordinate and the altitude record of starting point.
Step 204: during the user moved, locating module 16 can continue to detect user's's (electronic installation 10) itself current coordinate and height.
Step 206: the user when important intermediate point road sign (similarly being cross road branch point, the turning in path or the like), can be via controlling of operation and control interface 32 be reference coordinate and height with the coordinate and the altitude record of these intermediate points.
Step 208: the user can determine whether will turn back at any time when mobile.If user's decision will be turned back, just can trigger electronic installation 10 via operating and controlling interface 32, electronic installation 10 is come into operation in the return pattern.If the user does not also want to turn back, flow process 200 can operate on step 204-206-208 constantly repeatedly.
Step 302: after user's decision is turned back, the mode in the time of can selecting to recall the path via operating and controlling interface 32.If the user wants the former starting point of directly turning back back, the user can select the director pattern and proceed to step 306.If user path and recall each intermediate point one by one when wanting following, just can select the track subpattern and proceed to step 304.
Step 304: under the track subpattern, point to module 18 or height indicating module 22 can be earlier according to a up-to-date reference coordinate that writes down in the memory module and highly be used as benchmark, the guiding user moves towards this reference coordinate.As user during near (arriving at) this reference coordinate, point to module 18 or height indicating module 22 and come as benchmark with regard to available next (record early) reference coordinate, the indication user moves towards this reference coordinate, by that analogy.So, user's intermediate point that just can follow precedence record one by one moves.
Step 306: under the director pattern, point to module 18 or height indicating module 22 and can directly move (intermediate point of skipping other) with the indication user directly with the benchmark of former starting point as comparison towards former starting point.
Step 308: under the running of pointing to module 18 or height indicating module 22, the user just can follow sensing interface 20 or height to indicate the prompting of interface 24 and get back to former starting point.
In other words, in flow process 200, step 202 can be considered one along Cheng Chengxu to 208, and step 302 is to the 308 return programs that can be considered a correspondence.Come realization flow 200 with electronic installation 10 of the present invention, just can assist the user when losing one's way, successfully to turn back to former starting point.Also can learn by Fig. 3 and related description, when each reference coordinate person of being to use that memory module 30 is write down carries this electronic installation by way of coordinate, that is to say, when recalling the path, electronic installation 10 of the present invention need not provide the preset coordinate of each known fixed point with electronic chart, can point out the direction of user's return under the return pattern.
Please once again with reference to figure 1.During flow process 200 in carrying out Fig. 3, the landform module 26 in the electronic installation 10 of the present invention can assist the user to keep a terrain data, with the topographic relief number of times that is lived through in the record moving process; This terrain data can be stored in the memory module 30.When the user is beginning along setting out under the journey pattern when mobile, whenever the user through the tangible topographic relief in a place, for example be to get over the hilltop, a place, the user just can trigger landform module 26 via operating and controlling interface 32, and landform module 26 will increase progressively 1 with terrain data, represents the user to pass through a hilltop again more.Under the return pattern, when the user will turn back and recall the path, the user can trigger landform module 26 equally again through the hilltop, everywhere the time; And landform module 26 will make terrain data successively decrease 1.For instance, if the user just arrives a certain fixed point along having passed through 3 hilltops under the journey pattern, if will should be able to oppositely just can get back to former starting point through 3 hilltops once again from this fixed point former starting point of turning back back.So under the return pattern, the every triggering landform of user module 26, landform module 26 will make terrain data successively decrease 1, represents the hilltop of user's required process when turning back former starting point to lack one again.When terrain data was decremented to zero by the time, just representing between user position and the former starting point had not had the change of topographic relief.
Under the return pattern, the height tendency of the terrain data keeping or provide indicates user's landform that height indicating module 22 also can utilize landform module 26.When terrain data is not decremented to zero, represent the fluctuations that also can experience the landform height between user's current location and former starting point, so height indicating module 22 does not need to indicate clearly the user to move toward lower or toward eminence especially.When terrain data is decremented to zero, represent the change that has not had topographic relief between current position of user and the former starting point, height indicating module 22 just can be directly the current height of the height of the former starting point of foundation and user indicate the user to hoist away clearly or will walk to lower.For example, when terrain data had been decremented to zero if the reference coordinate height of former starting point is lower than the height of user's current location, height indicating module 22 just can be via just indicating interface 24 to indicate the user to move to the lower.
In the present invention, control the interface of multimedia and control the location and the interface of direction mechanism can be integrated into one, the user can be unified to control multimedia image, sound or the audio-visual broadcast and the running of location and direction mechanism with same operating and controlling interface.What Fig. 4 illustrated promptly is the situation that the present invention integrates the operating and controlling interface of image, sound or audio-visual broadcast and location and direction mechanism mutually.Please refer to Fig. 4 (and in the lump with reference to figure 1); On electronic installation 10 of the present invention, operating and controlling interface 32 can be provided with a viewing area 34 (a for example LCD) and a plurality of button 36A to 36D; Icon 38A, 38B in the viewing area 34 can be used for realizing the sensing interface 20 among Fig. 1 respectively and just indicate interface 24; Each button 36A to 36D can accept pressing of user and control.When controlling image, sound or audio-visual broadcast, pressing button 36A can make playing module 14 (Fig. 1) begin to play, button 36C, 36D represent last fragment (previous respectively, similarly be last first song or previous audio-visual chapters and sections) and back one fragment (next similarly is back one first song or back audio-visual chapters and sections); Pressing button 36B then can stop to play.
