Abstract

A method, a mobile device, and a computer-readable medium for displaying surrounding points of interest (POIs), adapted to a mobile device, are provided. In the present method, at least one keyword is received and set as a searching condition for searching POIs. When the mobile device obtains new current location information of the mobile device, a POI database is queried to find surrounding POIs of the current location that fit the searching condition. Finally, the searched POIs are updated and displayed.

in response to detecting the first current location, automatically querying a POI database according to the first current location to find surrounding POIs of the first current location satisfying the first searching condition to generate a first POI list and to find surrounding POIs of the first current location satisfying the second searching condition to generate a second POI list, wherein the first POI list and the second POI list are generated as independent pages with the first POI list displayed on top of the independent pages;

receiving a second input on the location update key;

detecting a second current location of the mobile device in response to the second input on the location update key, wherein the second current location is different from the first current location;

in response to detecting the second current location, automatically querying a POI database according to the second current location to find surrounding POIs of the second current location satisfying the first searching condition to generate a third POI list to replace the first POI list and to find surrounding POIs of the second current location satisfying the second searching condition to generate a fourth POI list to replace the second POI list;

receiving a third input comprising a touch-and-drag operation to switch the fourth POI list to the top of the independent pages; and

receiving a fourth input and displaying both the third POI list and the fourth POI list on the same independent page in response to receiving the fourth input.

2. The method according to claim 1, wherein the step of setting the first keyword as the first searching condition and the second keyword as the second searching condition comprises:

receiving a setting of POI category, wherein the first searching condition and the second searching condition further comprises the POI category for searching the POIs.

3. The method according to claim 2, further comprising displaying surrounding POIs satisfying the first keyword in categories according to the POI category and the first keyword in the first searching condition, and displaying surrounding POIs satisfying the second keyword in categories according to the POI category and the second keyword in the second searching condition.

4. The method according to claim 3, wherein the step of displaying the surrounding POIs in categories comprises:

displaying POIs of each of the POI categories, by the display, in an independent page; and

displaying the pages, by the display, corresponding to the POI categories in overlapping.

5. The method according to claim 1, wherein the step of setting the first keyword as the first searching condition and the second keyword as the second searching condition comprises:

receiving a searching distance input by a user, wherein the first searching condition and the second searching condition further comprises the POI category for searching the POIs.

12. The method according to claim 1, further comprising:

receiving an active operation of a POI list key input by a user;

displaying all POIs corresponding to the keyword in one independent page when receives the active operation.

13. The method according to claim 1, further comprising:

receiving a third keyword input by a user, by a processor of the mobile device, to preset as a third searching condition; and

receiving the touch-and-drag operation from the input device of the mobile device to switch the page of the second searching condition to the page of the third searching condition displayed on the display screen.

6. A mobile device for displaying surrounding points of interest (POIs), comprising:

an input device, configured to receive a first keyword and a second keyword input by a user, to receive a first input on a location update key to detect a first current location of the mobile device, to receive a second input on a location update key to detect a second current location of the mobile device, to receive a third input comprising a touch-and-drag operation and to receive a fourth input;

a communication positioning system, configured to execute positioning to obtain the first current location of the mobile device and the second current location of the mobile device, wherein the first current location is different from the second current location;

a setting circuit, configured to set the first keyword as the first searching condition and the second keyword as the second searching condition for searching a plurality of POIs;

a query circuit, configured to automatically find surrounding POIs of the first current location satisfying the first search condition to generate a first POI list, surrounding POIs of the first current location satisfying the second search condition to generate a second POI list, surrounding POIs of the second current location satisfying the first search condition to generate a third POI list, and surrounding POIs of the second current location satisfying the second search condition to generate a fourth POI list;

a display screen, configured to display the first POI list, the second POI list, the third POI list and a fourth POI list; and

a display circuit, configured to display the first POI list, the second POI list, the third POI list and the fourth POI list on the display screen,

wherein, in response to the detection of the first current location, the first POI list and the second POI list are generated as independent pages with the first POI list displayed on top of the independent pages,

wherein, in response to the detection of the second current location, the third POI list is generated to replace the first POI list and the fourth POI list is generated to replace the second POI list,

wherein, in response to the touch-and-drag operation, the forth POI list is switched to the top of the independent pages,

wherein, in response to the fourth input, both the third POI list and the fourth POI list are displayed on the same independent page.

7. The mobile device according to claim 6, wherein the input device further receives a setting of POI category, and the setting circuit sets the POI category as the first searching condition and the second searching condition for searching the POIs.

8. The mobile device according to claim 7, wherein the display circuit displays POIs satisfying the first keyword under each of the POI categories in categories according to the POI categories and the second keyword in the second searching condition, and the display circuit displays POIs satisfying the second keyword under each of the POI categories in categories according to the POI categories and the second keyword in the second search condition.

9. The mobile device according to claim 8, wherein the display circuit displays POIs of each of the POI categories in an independent page, and displays the pages corresponding to the POI categories in overlapping.
