Abstract

According to one embodiment, an electronic device includes a communication module, an electrical field strength detector, a state detector, an output module, and an output controller. The communication module transmits and receives a radio signal. The electrical field strength detector detects electrical field strength of the radio signal transmitted and received by the communication module. The state detector detects a first state where the electrical field strength detected by the electrical field strength detector increases with the lapse of time and a second state where the electrical field strength detected by the electrical field strength detector decreases with the lapse of time. The output controller controls output from the output module based on the first state and the second state.

Claims

an output module; and

an output controller configured to control output from the output module based on the first state and the second state.

2. The electronic device of claim 1, wherein the state detector is configured to detect the first state and the second state based on a change in the electrical field strength detected by the electrical field strength detector per unit of time.

the output controller is configured to control the output module such that intervals of the blinking light are configured to decrease in the first state and the intervals of the blinking light are configured to increase in the second state.

5. The electronic device of claim 2, wherein

the output module is configured to generate vibration, and

the output controller is configured to control the output module such that intervals of the vibration are configured to decrease in the first state and the intervals of the vibration are configured to increase in the second state.

6. The electronic device of claim 2, wherein

the output module is configured to display information, and

the output controller is configured to control the output module to display information indicating that communication state is improving in the first state and to display information indicating that communication state is degrading in the second state.

7. A communication state output method applied to an electronic device, the communication state output method comprising:

transmitting and receiving a radio signal;

detecting an electrical field strength of the transmitted and received radio signal;
