The electronic map in the present disclosure, for example, refers to a map having a control requirements in three-dimensional viewing angle, such as the electronic map with panoramic images, and the electronic maps modeled according to the three-dimensional spatial.
The control of the electronic map can be triggered by a variety of user operations, specific examples of user operations include, but are not limited to: dragging or swipe gestures, vibration, shaking or rotating the electronic apparatus, click on the interface buttons, menus, or icons, and so on. The present disclosure, the user operation for the electronic map is divided into a first user operation and a second user operation. The second user operation is triggered by detecting the rotation angle of the electronic apparatus within a length of time. The first user operation is triggered by all other user actions.
Referring to
In Step 110, the electronic apparatus detects a first user operation.
The detecting of the first user operation may be achieved by detecting events of interface object. The events include clicking, sliding, dragging, or double-clicking the object on the interface. In other words, when these events are triggered, the first user operation is detected. Of course, as mentioned above, the first user operation is not limited to the operation to the objects on the interface, but also can be implemented through various sensors such as a microphone, the vibration sensor or the like.
In Step 120, the electronic apparatus sets a viewing angle of the electronic map, in response to the first user operation.
In general, the value of the viewing angle of the electronic map can be directly obtained from the first user operation. For example, if a screen dragging of the electronic map is detected, the rotation angle is calculated according to drag distance. The viewing angle of the electronic map is rotated with the rotation angle in the drag direction of the screen dragging. As another example, if a rotation left button is pressed by users, the viewing angle of the electronic map is rotated with a predetermined angle associated with the rotation left button.
In Step 130, the electronic apparatus determines whether the first user operation is detected within a predetermined length of time. If yes, Step 140 is performed.
Step 130 and Step 140 may be performed respectively. The determining in the Step 130 may be dependent on the result of the Step 110. Specifically, once detecting the first user operation, the Step 150 will be performed. In Step 150, the electronic apparatus records the time point when the first user operation is detected. In the initial state, the operation start time of the method in the exemplary embodiment may be considered as the time point when the first user operation is detected. Periodically calculating an interval between the current time and the operation start time, and if the interval exceeds a predetermined length of time (e.g., 1 second), Step 140 will be performed. The periodically calculating can be implemented by a timer, and the specific interval can be set according actual needs.
In Step 140, the electronic apparatus sets the viewing angle of the electronic map according a posture of the electronic apparatus detected at current time.
The posture of the electronic apparatus refers to the posture of the electronic apparatus in a three-dimensional space, which generally can be described by a pitch angle, a yaw angle, and a roll angle.
In accordance with the embodiment, the electronic apparatus may set the viewing angle of the electronic map in response to the first user operation. The electronic apparatus also may set the viewing angle of the electronic map according a posture of the electronic apparatus detected at current time, if no first user operation is detected within a predetermined length of time. Therefore, using efficiency of the electronic map is significantly enhanced and the user operation time is also reduced.
Referring to
In Step 141, the electronic apparatus obtains reference posture parameters of itself.
It can be understood that, to get the reference posture parameters of electronic terminal, posture detection function of the electronic apparatus (related sensors such as gyroscopes) should be opened. If before Step 141, the posture detection function is not open, users need to open the relevant posture detection function, and then get posture parameters of electronic terminal, which was used as reference posture parameters of the electronic apparatus.
In the U.S. Apple's iOS operating system, for example, a space posture matrix can be obtained through CMAttitude class, and then posture angles, such as the pitch angle, the yaw angle and the roll angle can be obtained through the space posture matrix.
In Step 142, the electronic apparatus obtains current posture parameters of itself.
Every once in a while, current posture parameters of the electronic apparatus can be reacquired, similar with Step 141,
In Step 143, the electronic apparatus obtains a rotation angle of itself according to the reference posture parameters and the current posture parameters.
The rotation angle of the electronic apparatus can be obtained by calculating the difference between the current posture angle obtained in Step 142 and the posture angle obtained in Step 141, as mentioned above in each direction.
It can be understood that, there is a mapping relationship between the pitch angle, the yaw angle, and the roll angle of the electronic apparatus and the coordinate system thereof. As shown in
In Step 144, the electronic apparatus sets the viewing angle of the electronic map according to the rotation angle thereof.
Due to various reasons (e.g., hand instability), the electronic apparatus may be shake in a relatively small amplitude. In this condition, the rotation angle obtained in Step 144 is a smaller value, and frequently adjusting the viewing angle of the electronic map will affect the normal use of the electronic apparatus. Thus, in Step 144, if the rotation angle of the electronic apparatus is smaller than a predetermined value, such as 10 degrees, the viewing angle is kept unchanged.
It can be understood that, the above-mentioned Step 141 may be performed only once, and then Step 142 to Step 144 are repeated. So long as the user changes the position of the electronic apparatus, the viewing angle of the electronic map can be adjusted.
Further, after Step 110, if the first user operation is detected, the posture detection function of the electronic apparatus may be closed to avoid interference.
Referring to
In Step 145, if a pitch angle of the electronic apparatus being within a predetermined range, the electronic apparatus sets the pitch angle as the viewing angle of the electronic map.
The predetermined range, for example, may be a range from about 80 degrees to about 100 degrees.
It can be understood that, in normal use, the pitch angle of the electronic apparatus is about 45 degrees. At this time, a horizontal viewing angle will be displayed in accordance with using habit. In this context, if the user moves the electronic apparatus to a direction, wherein the longitudinal axis of the electronic apparatus is in a vertical direction, according to the viewing angle setting process of the aforementioned embodiments, the electronic map will show the sky. In this condition, the electronic map displays less useful information. If setting the pitch angle as the viewing angle of the electronic map, the pitch angle of the electronic map will be exactly the same with the pitch angle of the electronic apparatus, so that the electronic map can display more useful information.
Referring to
In Step 160, if the first user operation is a predetermined operation, the electronic apparatus sets a predetermined viewing angle as the viewing angle of the electronic map.
The predetermined viewing angle may include a default viewing angle of the electronic map, such as a 0 degree pitch angle, a 0 degree yaw angle, and a 0 degree roll angle.
The predetermined user operation, for example, may include a predetermined voice order or a vibration within a predetermined frequency range and all the like. The predetermined user operation may also be a rotation of the electronic apparatus to a specific angle by users. Referring to
As described in the third embodiment, when the pitch angle of the electronic apparatus is about 45 degrees, the viewing angle of the electronic map is a horizontal viewing angle. According to the real-time adjustment of the electronic map according to the rotation angle of the electronic apparatus, in the foregoing embodiment, the viewing angle of the electronic map should be the viewing angle shown in
It can be understood that, according to the above steps, the viewing angle can be easily restored to the default viewing angle, so that the efficiency of the map control is improved and the operating time of users are reduced.

The electronic apparatus also may set the viewing angle of the electronic map according a posture of the electronic apparatus detected at current time, if no first user operation is detected within a predetermined length of time. Therefore, using efficiency of the electronic map is significantly enhanced and the user operation time is also reduced.
