Abstract

A method for avoiding wrong input by determining the environmental situation and the system using the method are provided. The system of the present invention includes a light-sensitive element, a processor and an input device. The light-sensitive element and the input device are electrically connected to the processor respectively. The light-sensitive element generates a light state responsive to an external light source, and the light state can change with the external light source. A processor selectively refuses to execute a partial request signal transmitted from the input device according to the light state. The method of the present invention includes: (a) detecting the light state of the light-sensitive element by the processor; (b) determining the environmental situation as in a normal state or a specific state; and (c) when the environmental situation is in the specific state, the processor refuses to execute the partial request signal from the input device.

Claims

1. A method for avoiding wrong input to an electronic apparatus based on an environmental situation, the electronic apparatus including a light-sensitive element, a processor and an input device, the light-sensitive element and the input device electrically connected to the processor respectively, the light-sensitive element, responsive to the environmental situation, generating a light state, the input device selectively transmitting a request signal to the processor, the method comprising:

(a) detecting the light state of the light-sensitive element by the processor;

(b) determining whether the environmental situation is in a normal state or a specific state based on the light state; and

(c) when the environmental situation is in the specific state, the processor selectively executsing partial request signal.

2. The method of claim 1, wherein the processor includes a timer, the step (a) further comprising:

initiating the timer to count down a time interval; and

checking the light state of the light-sensitive element by the processor as the time interval elapses.

3. The method of claim 2, wherein the step (a) further comprises:

when the light state is detected as a first state, re-initiating the timer to count down the time interval.

4. The method of claim 1, wherein the step (b) further comprises:

when the light state is detected as a first state, the environmental situation is determined as in the normal state.

5. The method of claim 1, wherein the step (b) further comprises:

when the light state is detected as a second state, the environmental situation is determined as in the specific state.

6. The method of claim 1, wherein the processor includes a timer, the timer including an initial count value, the step (b) further comprising:

when the light state is a second state, a specific value is added to the initial count value; and

when the initial count value equals to or greater than a predetermined value, the processor determines the environmental situation as in the specific state.

7. The method of claim 6, wherein the step (b) further comprises:

when the light state is a first state, re-initiating the timer.

8. The method of claim 6, the step (a) further comprising:

initiating the timer to count down a time interval; and

detecting the light state of the light-sensitive element as the time interval elapses; and

the step (b) further comprising;

when the initial count value is less than the predetermined value, re-initiating the timer to count down the time interval.

9. A system for avoiding accident input to an electronic apparatus based on an environmental situation, the system comprising:

a light-sensitive element;

a processor electrically connected to the light-sensitive element; and

an input device electrically connected to processor;

wherein the light-sensitive element, responsive to the environmental situation, generates a light state, the input device selectively transmits a request signal to the processor, and when the light state is a specific state, the processor selectively executes the request signal.

10. The system of claim 9, wherein the processor includes a timer to count down a time interval.
