Title: Computing system with a map auto-zoom mechanism and method of operation thereof

Description:
TECHNICAL FIELD 
     An embodiment of the present invention relates generally to a computing system and more particularly to a computing system with an auto-zoom mechanism. 
     BACKGROUND 
     Modern consumer and industrial electronics, especially devices such as cellular phones, smart phones, tablet computers, laptops, vehicle integrated computing and communication systems, vehicle navigation systems, portable digital assistants, and combination devices, are providing increasing levels of functionality to support modern life including communication services. Research and development in the existing technologies can take a myriad of different directions. 
     Users of connected computing systems (i.e. systems that use connectivity to provide navigation information like maps, Points of Interest (POIs), street names, directions, traffic conditions, speed limits, etc.) often rely on the presentation of a map for guidance on a route, locating destinations, and navigating a maneuver. However, users are often challenged by the usability while traveling to provide the optimal amount of map information. 
     Thus, a need still remains for a computing system with an auto-zoom mechanism and method to improve the usability. In view of the ever-increasing commercial competitive pressures, along with growing consumer expectations and the diminishing opportunities for meaningful product differentiation in the marketplace, it is increasingly critical that answers be found to these problems. Additionally, the need to improve efficiencies and performance, and meet competitive pressures adds an even greater urgency to the critical necessity for finding answers to these problems. 
     Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.

     DETAILED DESCRIPTION 
     Embodiments provide the computing system can increase the presentation of the map to the user by automatically adjusting the zoom level of the map. The auto-zoom mechanism provides for the display of the map at a zoom level based on the speed limit of the current location of the user to provide a look ahead distance. 
     Embodiments provide the computing system can detect a change in the speed limit for a road segment based on the current location of the user. The correct detection of the change in the speed limit allows for a transition by the computing system that improves operator awareness. 
     Embodiments provide the computing system can set a zoom level by determining a road type when the speed limit is unavailable. The setting of a zoom level based on a road type allows the computing system with an auto-zoom mechanism to function even when the speed limit of the current location of the user cannot be determined.

     The second location unit  246  can generate location information, current heading, current acceleration, and current speed of the second device  106 , as examples. The second location unit  246  can be implemented in many ways. For example, the second location unit  246  can function as at least a part of a global positioning system (GPS) and can include components, such as a GPS receiver, an inertial navigation system, a cellular-tower location system, or any combination thereof. 
     The second location unit  246  can include a second location interface  252 . The second location interface  252  can be used for communication between the second location unit  246  and other functional units or circuits in the second device  106 . The second location interface  252  can also be used for communication that is external to the second device  106 . The second location interface  252  can be implemented with technologies and techniques similar to the implementation of the second control interface  236 . 
     Functionality of the computing system  100  can be provided by the first control unit  210 , the second control unit  238 , or a combination thereof.

For example, the second software  244  can be partitioned differently such that some or all of its function can be in the second control unit  238  and the second communication unit  226 . Also, the second device  106  can include other functional units not shown in  FIG. 2  for clarity. 
     The first device  102  can have a similar or different partition as the second device  106 . The functional units or circuits in the first device  102  can work individually and independently of the other functional units or circuits. The first device  102  can work individually and independently from the second device  106  and the communication path  104 . 
     The functional units in the second device  106  can work individually and independently of the other functional units or circuits. The second device  106  can work individually and independently from the first device  102  and the communication path  104 . 
     The functional units or circuits described above can be implemented in hardware. For example, one or more of the functional units or circuits can be implemented using a gate, circuitry, a processor, a computer, integrated circuit, integrated circuit cores, a pressure sensor, an inertial sensor, a microelectromechanical system (MEMS), a passive device, a physical non-transitory memory medium containing instructions for performing the software function, a portion therein, or a combination thereof. 
     For illustrative purposes, the computing system  100  is described by operation of the first device  102  and the second device  106 . It is understood that the first device  102  and the second device  106  can operate any of the modules, units, and functions of the computing system  100 . 
     Referring now to  FIG. 3 , therein is shown an exemplary display of the computing system  100  of  FIG. 1  with an active map area  302  and a current zoom level  306 . The active map area  302  is the size and proportion of the first display interface  206  of  FIG. 2 , the second display interface  234  of  FIG. 2 , or a combination thereof that displays a map  310 . The computing system  100  can obtain the width, height, and aspect ratio of the active map area  302  utilizing the first control unit  210  of  FIG. 2 , the second control unit  238  of  FIG. 2 , or a combination thereof. The computing system  100  can also obtain the measurements for the active map area  302  from the first display interface  206 , the second display interface  234 , or a combination thereof. 
     The map  310  is a visual representation of a geographic area. For example, the map  310  can be a representation of a state, a city, a town, a neighborhood, or any portion thereof. As a further example, the map  310  can represent the roadways in the geographic area. The map  310  can be displayed by the first display interface  206  of  FIG. 2 , the second display interface  234  of  FIG. 2 , or a combination thereof. The map  310  can be displayed in relation to a current location  304 . 
     The current location  304  is generated by the first location unit  214  of  FIG. 2 , the second location unit  246  of  FIG. 2 , or a combination thereof. For example, the current location  304  provide a location of the first device  102  of  FIG. 1  or the second device  106  of  FIG. 1 . The current location  304  can be generated in a number of ways. For example, the current location  304  can be determined by a global positioning system (GPS), cellular triangulation, wireless fidelity (WiFi) triangulation, dead reckoning, or a combination thereof. The computing system  100 , the first device  102  of  FIG. 1 , the second device  106  of  FIG. 2 , or a combination thereof can track the current location  304  dynamically and in real time. 
     The computing system  100  tracking the current location  304  “dynamically” refers to the receiving, monitoring, or a combination thereof of the current location  304  that is non-static or by potentially differing mechanism. The computing system  100  tracking the current location  304  “real time” refers to the receiving, monitoring, or a combination thereof of the current location  304  at the time of reading for the current location  304  is taken regardless of the mechanism at some time period. The computing system  100  can display the current location  304  on the first display interface  206 , the second display interface  234 , or a combination thereof. 
     The computing system  100  can display the current location  304  in a directionality  312 . The directionality  312  is the orientation towards that for movement. The directionality  312  can be determined by calculating the change in the current location  304  or based on dead reckoning, such as with an accelerometer or a gyroscope in the first location unit  214 , the second location unit  246 , or a combination thereof. For example, the directionality  312  can be determined based on the change in degrees of latitude, longitude, altitude, or a combination thereof, of the current location  304 . 
     The computing system  100  can utilize the current location  304  to obtain map information  314 . The map information  314  refers to a diagram or a collection of data representing an arrangement or distribution of geographic features, physical features, non-physical features, or a combination thereof of the geographic location on a map. For example, the map information  314  can include a physical feature such as a path, a road sign, street name, an infrastructure, a geographical feature, a natural topology, points of interest, buildings, bodies of water, or a combination thereof. As a further example, the map information  314  can also include a non-physical feature such as a speed limit, a one-way designation, an address, points of interest (POI) or a combination thereof. The aforementioned list is not meant to be limiting. 
     The computing system  100  can request and receive the map information  314  using the first communication unit  214  of  FIG. 2 , the second communication unit  226  of  FIG. 2 , or a combination thereof. The computing system  100  can cache the map information  314  using the first storage unit  216  of  FIG. 2 , the second storage unit  240  of  FIG. 2 , an external database, or a combination thereof. 
     The computing system  100  can obtain the map information  314  to determine a current road segment  316 , a current speed limit  318 , a current road type  320  or a combination thereof. The current road segment  316  is the roadway or a portion of the roadway on which the user is currently travelling. For example, the current road segment  316  can be a street, an alleyway, a highway, a freeway, a parkway, an expressway, a toll road, a residential road, or an unpaved path. The aforementioned list is not meant to be limiting. The current road segment  316  can be determined based on the current location  304 . 
     The current speed limit  318  is the designated maximum legal travel rate for a current road segment  316 . For example, the computing system  100  can determine the current speed limit  318  from the map information  314  obtained from the second device  106 , an external entity, an external system, or a combination thereof. As a further example, the computing system  100  can determine the current speed limit  318  utilizing sensors such as a camera, an infrared detector, a radar detector, a light detection and ranging (LIDAR) unit, or a combination thereof. 
     The current road type  320  is the classification of a roadway. The current road type  320  can be classified in a number of ways. For example, the current road type  320  can be based on a segment speed limit  336 , traffic conditions, traffic limiters as traffic lights or stop signs, or designation has highway or expressway or freeway, residential area, or a combination thereof. The segment speed limit  336  is the estimated speed limit for the current road segment  316  when the current speed limit  306  is unavailable or unobtainable. The segment speed limit  336  can be determined by a number of factors. For example, the segment speed limit  336  can be based on the number of lanes, the number of intersections, the speed limit of roadways nearby, the geographic area, or a combination thereof. The aforementioned list is not meant to be a limiting and closed list but described as examples. The segment speed limit  336  can be determined utilizing the map  310 , the map information  314 , or a combination thereof. 
     Continuing with the example, the current zoom level  306  can be displayed on the first display interface  206 , the second display interface  234 , or a combination thereof. The current zoom level  206  is a view of the map  310  based on a look ahead distance  308 . The look ahead distance  308  is the physical distance between the current location  304  and the real world location of the top edge of the map  310  displayed the active map area  302 . The look ahead distance  308  is calculated based on a minimum distance  334  and a look ahead distance multiplier  322 . 
     The minimum distance  334  is the minimum value for the look ahead distance  308  based on a range of speed limits. The minimum distance  334  can be predefined. The minimum distance  334  can be represented using categorizations. The categorizations can indicate the ranges of speed limits. For example, the categorizations can be a low speed distance  336 , a mid speed distance  338 , a high speed distance  340 , and a max speed distance  342 . 
     The low speed distance  336  requires the shortest instance of the minimum distance  334 . For example, the low speed distance  336  can require the minimum distance  334  of 1000 feet when speed limit is below 30 miles per hour. The mid speed distance  338  provides an instance of the minimum distance  334  that is longer than the low speed distance  336  and shorter than the high speed distance  340 . For example, the mid speed distance  338  can provide the minimum distance  334  of 2000 feet when the speed limit is at least 30 miles per hour and below 45 miles per hour. 
     The high speed distance  340  can require an instance of the minimum distance  334  that is longer than the mid speed distance  338  and shorter than the max speed distance  342 . For example, the high speed distance  340  can require the minimum distance  334  of 0.8 miles when the speed limit is at least 45 miles per hour and below 65 miles per hour. The max speed distance  342  can require an instance of the minimum distance  334  that is longer than the higher speed distance  340 . For example, the max speed distance  342  can require the minimum distance  334  of 1.6 miles when the speed limit is at least 65 miles per hour. The computing system  100  can obtain the minimum distance  334  from the second device  106 , an external entity, an external system, or a combination thereof. The computing system  100  can store the minimum distance  334  in the first storage interface  216 , the second storage interface  240 , or a combination thereof. 
     The look ahead distance multiplier  322  is a value of at least 1 that is multiplied with the minimum distance  334  to obtain the look ahead distance  308 . The look ahead distance multiplier  322  adjusts the minimum distance  334  based on the active map area  302 . The look ahead distance multiplier  322  can increase when the width-to-height ratio of the active map area  302  decreases. For example, the look ahead distance multiplier  322  can be 1.2 when the active map area  302  of the first display interface  206  has a width to height ratio of 0.75. As a further example, the look ahead distance multiplier  322  can be 1.4 when the active map area  302  of the second display interface  234  has a width to height ratio of 0.5. The computing system  100  can calculate the look ahead distance multiplier  322  with the first control unit  210 , the second control unit  238 , or a combination thereof. The computing system  100  can calculate the look ahead distance  308  by multiplying the minimum distance  334  with the look ahead distance multiplier  322  with the first control unit  210 , the second control unit  238 , or a combination thereof. 
     The computing system  100  can generate a camera view  324  based on the look ahead distance  308 . The camera view  324  is the degree of inclination angle and magnification of the map  310  displayed in the active map area  302 . The camera view  324  can be represented using categorizations. The categorizations can indicate the ranges of the look ahead distance  308 . For example, the categorizations can be a low speed view  311 , a mid speed view  313 , a high speed view  315 , and a max speed view  317 . 
     The low speed view  326  can represent the camera view  324  of the map  310  that provides the shortest instance of the look ahead distance  308 . For example, the low speed zoom  326  can provides the smallest view of the map  310  from the point of view directly above the current location  304 , also known as an overhead view. The mid speed zoom  328  can represent the camera view  324  of the map  310  that provides an instance of the look ahead distance  308  that is longer than the low speed zoom  326  and shorter than the high speed zoom  330 . For example, the mid speed zoom  328  can provide a view of the map  310  that is larger than the low speed zoom  326  and smaller than the high speed zoom  330  from the point of view that is angled at a low degree of inclination, also known as bird&#39;s-eye view. 
     The high speed zoom  330  can represent the camera view  324  of the map  310  that provides an instance of the look ahead distance  308  that is longer than the mid speed zoom  328  and shorter than the max speed zoom  332 . For example, the high speed zoom  330  can provide a view of the map  310  that is larger than mid speed zoom  328  and smaller than the max speed zoom  332  from the point of view that is angled at a higher degree of inclination than the mid speed zoom  328 . The max speed zoom  332  can represents the camera view  324  of the map  310  that provides an instance of the look ahead distance  308  that is longer than the higher speed zoom  330 . For example, the max speed zoom  332  can provide the largest view of the map  310  from the point of view that is angled at the highest degree of inclination. 
     The computing system  100  can generate the camera view  324  as the low speed zoom  326 , the mid speed zoom  328 , the high speed zoom  330 , the max speed zoom  332  based on the look ahead distance  308 . The computing system  100  can generate the camera view  324  with the first control unit  210 , the second control unit  238 , or a combination thereof. The computing system  100  can generate the camera view  324  with the first control unit  210 , the second control unit  238 , or a combination thereof. 
     Continuing with the example, the computing system  100  can generate the current zoom level  306  by generating the camera view  324  based on the look ahead distance  308  for the current speed limit  318 , the current road type  320 , or a combination thereof. The computing system  100  can generate the current zoom level  306  utilizing the camera view  324  and the look ahead distance  308  with the first control unit  210 , the second control unit  238 , or a combination thereof. 
     Referring now to  FIG. 4 , therein is an exemplary display interface of the computing system  100  of  FIG. 1  when operating in an active guidance mode  402 . The active guidance mode  402  refers to a mode of the computing system  100  where the computing system  100  calculates a route for the user to follow to reach a route destination  404 . For example, the active guidance mode  402  can provide instructions for guidance of a route for the user or a vehicle to follow. As a specific example, the guidance can include step-by-step instructions to traverse the route. 
     The route destination  404  refers to a geographic location or point of interest that the user wants to navigate to. The route destination  404  can include the end point or the termination of the route or the guidance. The route destination  404  can also include waypoints or intermediate stops. For example, the route destination  404  can be a store, a landmark, an office building or site, a park, an address, a general geographic area, a street, a city or municipality, or a combination thereof. Also for example, a waypoint for the route can represent the route destination  404  when the guidance is terminated at that particular instance of the waypoint. 
     For brevity of description, in this embodiment, reference to the first display interface  206  and the first user interface  254  of  FIG. 2  is made, however, the descriptions with respect to the first display interface  206  and the first user interface  256  can be similarly applicable to the second display interface  234  and the second user interface  228  of  FIG. 2 . 
     In one embodiment, the first display interface  206 , in conjunction with the first user interface  254 , can enable a user of the computing system  100  to input the route destination  404  to enable the active guidance mode  402  of the computing system  100 . The user can input the route destination  404  by using alpha-numeric characters, symbols, voice commands, gestures, or a combination thereof. For example, the user can input the route destination  404  by interfacing with the first user interface  254 , the second user interface  228 , or a combination thereof. As a further example, the user can input the route destination  404  by interfacing with the first audio interface  204  of  FIG. 2 , the second audio interface  232  of  FIG. 2 , or a combination thereof. 
     Continuing with the example, once the route destination  404  is input by the user, the computing system  100  can determine a travel route  406  for the user to navigate. The travel route  406  is the path to navigate from a current location  304  to the route destination  404 . For example, the travel route  406  can be determined based on closest distance to the route destination  404 , fastest time of arrival to the route destination  404 , avoidance of tolls to the route destination  404 , or other constraints. 
     Continuing with the example, the first display interface  206  can display the travel route  406  and any additional instances of the travel route  406  generated based on the different constraints. For example, the navigation system  100  can display the travel route  406  based on the shortest distance to the route destination  404 . As another example, the computing system  100  can display the travel route  406  based on a fastest time of arrival to the route destination  404 . As a further example, the computing system  100  can display the travel route  406  based on road constraints, such as avoid toll roads or avoid freeways. 
     Continuing with the example, the first display interface  206  can display the current location  304 . The current location  304  can represent the starting point that determines the travel route  406  to the route destination  404 . The current location  304  can also represent the present location along the travel route  406  to the route destination  404 . 
     Continuing with the example, the computing system  100  can provide step-by-step guidance to the user for a maneuver  408 . The maneuver  408  is a movement or series of movement to continue on the current road segment  316  or to travel from the current road segment  316  to a further road segment  410 . For example, the maneuver  408  can be a merger, a turn, a U-turn, a lane change, an exit, an entrance, a roundabout, or a combination thereof. The aforementioned list is not meant to be limiting. The computing system  100  can provide visual instructions to the user on the first display interface  206 . As a further example, the computing system  100  can provide audible instructions to the user through the first audio interface  204 , the second audio interface  232 , or a combination thereof. The computing system  100  can determine the maneuver  408  from the map  310 , the map information  314 , or a combination thereof obtained from the second device  106 , an external entity, an external system, or a combination thereof. As a further example, the computing system  100  can determine the maneuver  408  utilizing sensors such as a camera, an infrared detector, a radar detector, a light detection and ranging (LIDAR) unit, or a combination thereof. 
     The further road segment  410  is the roadway that is connected to the current road segment  316  with the maneuver  408 . The further road segment  410  is not the current road segment  316 . For example, the further road segment  410  can be the next roadway that the user will need to travel on the travel route  406  to the route destination  404 . As a further example, the further road segment  410  can be the roadway that the user will enter upon completing the maneuver  408  from the current road segment  316 . The computing system  100  can determine the further road segment  410  and any additional instances of the further road segment  410  with the first control unit  210 , the second control unit  240 , or a combination thereof. 
     The computing system  100  can determine a further speed limit  412  for the further road segment  410  and any additional instances of the further road segment  410 . The further speed limit  412  is the designated maximum legal travel rate on the further road segment  410 . The computing system  100  can determine the further speed limit  412  from the map  310  of  FIG. 3 , the map information  314  of  FIG. 3 , or a combination thereof. The further speed limit  412  can be obtained from the second device  106 , an external entity, an external system, or a combination thereof. As a further example, the computing system  100  can determine the further speed limit  412  utilizing sensors such as a camera, an infrared detector, a radar detector, a light detection and ranging (LIDAR) unit, or a combination thereof. 
     The computing system  100  can automatically set a further zoom level  414  upon determining the further speed limit  412 . The further zoom level  414  is the camera view  324  of the map  310  automatically set utilizing the look ahead distance  308  based on the further speed limit  412 . For example, the further zoom level  414  can be set with the low speed view  311  when the further speed limit  412  requires the look ahead distance  308  based on the low speed distance  336 . As a further example, the further zoom level can be set with the high speed view  315  when the further speed limit  412  requires the look ahead distance  308  based on the high speed distance  340 . 
     The computing system  100  generate the further zoom level  414  “automatically” refers to the setting, generating, or a combination thereof of the further zoom level  414  for the further road segment  410  based on the further speed limit  412  without input from the user. The computing system  100  can generate the further zoom level  414  based on the look ahead distance  308  for the further speed limit  412  with the first control unit  210 , the second control unit  238 , or a combination thereof. 
     The computing system  100  can also automatically determine the further zoom level  414  based on a further road type  416 . The further road type  416  is the classification of a roadway based on the segment speed limit  336  for the further road segment  416 . For example, the further road type  416  can be determined to be the low speed road  338 , the mid speed road  340 , the high speed road  342 , or the max speed road  344 . The computing system  100  can determine the further road type  416  for the further road segment  410  when the further speed limit  412  is unobtainable or unavailable. 
     The computing system  100  can determine the segment speed limit  336  of the further road type  416  utilizing the map  310 , the map information  314 , or a combination thereof. For example, the computing system  100  can determine the segment speed limit  336  of the further road type  416  from the map information  314  obtained from the second device  106 , an external entity, an external system, or a combination thereof. 
     The computing system  100  setting the further zoom level  414  “automatically” refers to the setting, generating, or a combination thereof of the further zoom level  414  for the further road segment  410  based on the further road type  416  without input from the user. The computing system  100  can set the further zoom level  414  with the first control unit  210 , the second control unit  238 , or a combination thereof. The computing system  100  can generate the further zoom level  414  based on the look ahead distance  308  for the further road type  416  with the first control unit  210 , the second control unit  238 , or a combination thereof. 
     Referring now to  FIG. 5 , an exemplary display of the computing system  100  of  FIG. 1  when operating in a free drive mode  502 . The free drive mode  502  refers to a mode of the computing system  100  where the computing system  100  operates without input of the route destination  404  of  FIG. 4 . The computing system  100  operates in the free drive mode  502  without the active guidance mode  402  of  FIG. 4 . 
     During operation in the free drive mode  502 , the computing system  100  can be operating without a predetermined location for the route destination  404  of  FIG. 4 .

     The computing system  100  can detect a speed change  506  based on the current speed limit  318 , the current travel speed  504 , or a combination thereof. The speed change  506  occurs when the current speed limit  318 , the current travel speed  504 , or combination thereof falls outside the range of the speed limits for the minimum distance  320  of the current zoom level  306 . For example, the speed change  506  is detected when the current travel speed  504  exceeds the upper speed limit range of the minimum distance  320  of  FIG. 3  of the current zoom level  306 .

The active area module  602  can store the look ahead distance multiplier  332  on the first storage unit  216  of  FIG. 2 , the second storage unit  240  of  FIG. 2 , or a combination thereof. Once the active area module  602  determines the look ahead distance multiplier  322 , control is passed to the user input module  604  to enable the receiving of the route destination  404  of  FIG. 4  by the user of the computing system  100 . 
     The user input module  604  can detect whether the user of the computing system  100  has input the route destination  404  of  FIG. 4  by interfacing with the first user interface  254  of  FIG. 2 , the second user interface  228  of  FIG. 2 , or a combination thereof. The user input module  604  can set one or more of the flags  618  indicating that the user has input the route destination  404 . The flags  618  refer to a software or hardware mark, variable, condition, or a combination thereof that signals a particular condition or status. For example, the user input module  604  can detect whether the user has input alpha-numeric characters or symbols indicating the route destination  404  by interfacing with the first display interface  206 , the second display interface  234 , or a combination thereof.

     The map display module  610  can determine the camera view  324  for the current zoom level  306  and the updated zoom level  506  with the first control unit  210 , the second control unit  238 , or a combination thereof. The map display module  610  can determine the current travel speed  506  with the first location unit  214 , the second location unit  246 , or a combination thereof. The map display module  610  can transmit the current zoom level  306  for displaying with the first communication unit  214 , the second communication unit  226 , or a combination thereof. Once the map display module  610  displays the current location  304 , the directionality  312 , the map  310 , the map information  314 , the current zoom level  306 , the updated zoom level  506 , or a combination thereof, control is passed to the preparation module  612  to set the further zoom level  414  of  FIG. 4 . 
     The preparation module  612  sets the further zoom level  414  for the further road segment  410  by determining the further speed limit  412 , the further road type  416 , or a combination thereof. In an embodiment where the computing system  100  is operating in the active guidance mode  402 , the preparation module  612  can determine the further road segment  410  based on the travel route  406  and any additional instances of the travel route  406  to the route destination  404 .
