Abstract

Method, apparatus and computer-readable medium for detecting a condition for an surrounding environment of a mobile device are disclosed. The mobile device may generate a prompting information and control presentation of the prompting information based on at least the detected condition of the surrounding environment.

First claim

What is claimed is:

1 . A method for generating travel path prompt information on a mobile device , the method comprising:
receiving a trigger instruction by a mobile device; in response to receiving the trigger instruction, controlling an environmental sensor of the mobile device to automatically detect a condition of a surrounding environment within a predetermined range from the mobile device; determining whether an obstacle is identified in the surrounding environment within the predetermined range based on the detected condition; and controlling presentation of prompt information by the mobile device when the obstacle is identified in the surrounding environment within the predetermined range.

2 . The method of claim 1 , wherein controlling the environmental sensor to detect the condition of the surrounding environment comprises:
determining a distance between the mobile device and a nearest object, and determining the obstacle is identified within the predetermined range when the distance between the mobile device and the nearest object is within the predetermined range; or determining an area of an object identified in the surrounding environment within the predetermined range, and determining the obstacle is identified within the predetermined range when the area of the object is greater than a first predetermined threshold.

3 . The method of claim 1 , wherein controlling presentation of the prompt information comprises at least one of:
obtaining a pre-stored first voice prompt file and playing the first voice prompt file; generating a second voice prompt file according to the detected condition of the surrounding environment within the predetermined range, and playing the second voice prompt file; generating a third voice prompt file according to the detected condition of the surrounding environment within the predetermined range and a movement speed of the mobile device, and playing the third voice prompt file; or controlling an indicator light included in the mobile device to switch between an on state and an off state according to a predetermined frequency.

4 . The method of claim 3 , wherein generating the third voice prompt file according to the detected condition of the surrounding environment within the predetermined range and the movement speed of the mobile device comprises:
obtaining the movement speed of the mobile device; calculating, based on the distance between the mobile device and a nearest object and the movement speed, time for the mobile device to reach the nearest object; and generating the third voice prompt file when the time is less than a second predetermined threshold.

5 . The method of claim 1 , wherein the trigger instruction corresponds to a state of a flashlight included in the mobile device being in an on state, and the environmental sensor comprises a proximity sensor.

6 . The method of claim 5 , wherein the proximity sensor comprises an infrared proximity sensor or a ultrasonic proximity sensor.

7 . An apparatus for travel path condition prompt, comprising:
a processor; a memory in communication with the processor and configured to store processor-executable instructions; wherein the processor is configured to execute the instructions to:
receive a trigger instruction by a mobile device;
in response to receiving the trigger instruction, control an environmental sensor of the mobile device to automatically detect a condition of a surrounding environment within a predetermined range from the mobile device;
determine whether an obstacle is identified in the surrounding environment within the predetermined range based on the detected condition; and
control presentation of prompt information by the mobile device when the obstacle is identified in the surrounding environment within the predetermined range.

8 . The apparatus of claim 7 , wherein the processor is further configured to execute the instructions to:
determine a distance between the mobile device and a nearest object and determine that there is an obstacle on the surrounding environment within the predetermined range when the distance between the mobile device and the nearest object is within the predetermined range; or determine an area of an object identified in the surrounding environment within the predetermined range, and determine the obstacle is identified within the predetermined range when the area of the object is greater than a first predetermined threshold.

9 . The apparatus of claim 7 , wherein the processor is further configured to execute the instructions to:
obtain a pre-stored first voice prompt file and playing the first voice prompt file; generate a second voice prompt file according to the detected condition of the surrounding environment within the predetermined range, and play the second voice prompt file; generate a third voice prompt file according to the detected condition of the surrounding environment within the predetermined range and a movement speed of the mobile device, and play the third voice prompt file; or control an indicator light included in the mobile device to switch between an on state and an off state according to a predetermined frequency.

10 . The apparatus of claim 9 , wherein the processor is further configured to execute the instructions to:
obtain the movement speed of the mobile device; calculate, based on the distance between the mobile device and a nearest object and the movement speed, time for the mobile device to reach the nearest object; and generate the third voice prompt file when the time is less than a second predetermined threshold.

11 . The apparatus of claim 7 , wherein the processor is further configured to execute the instructions to control a proximity sensor included on the mobile device to detect the condition of the surrounding environment within the predetermined range when a trigger instruction corresponding to a state of a flashlight included in the mobile device being in an on state is received.

12 . The apparatus of claim 11 , wherein the proximity sensor comprises an infrared proximity sensor or an ultrasonic proximity sensor.

13 . A non-transitory computer readable storage medium having stored therein instructions that, when executed by a processor of a mobile device, cause the mobile device to:
receive a trigger instruction by a mobile device; in response to receiving the trigger instruction, control an environmental sensor of the mobile device to automatically detect a condition of a surrounding environment within a predetermined range from the mobile device; determine whether an obstacle is identified in the surrounding environment within the predetermined range based on the detected condition; and control presentation of prompt information by the mobile device when the obstacle is identified in the surrounding environment within the predetermined range.
