Mobile Terminal Position-Based Output Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wrist terminals struggle to provide effective information output while users are engaged in activities that prevent them from viewing the screen, such as driving or cycling, as existing methods either require screen viewing or rely solely on vibration or sound, which may not provide sufficient information.
Innovation Solution
A mobile terminal with a voice input unit, a display unit, and a sensor system that detects its position relative to the user's mouth, controlling the output method to switch between screen display, sound, and vibration based on the detected position, ensuring information is conveyed suitably for the user's activity.

Engineering Contradiction Analysis
1Loss of information
If the terminal outputs information on the screen, then the information delivery is rich and detailed, but the user cannot view the screen during activities like driving or cycling
Solution Approach 1:
The terminal dynamically switches between screen display and other output methods (sound, vibration) based on the detected position of the terminal relative to the user's mouth. When the terminal is near the mouth (indicating the user is engaged in an activity), the system automatically switches to non-visual output. When the terminal is away from the mouth, it switches to screen display, providing adaptive information delivery that responds to user context.
2Ease of operation
If the terminal uses only sound or vibration for output, then the user can receive information during activities, but the information delivery is insufficient and not rich enough
Solution Approach 1:
The terminal employs multiple output methods (screen display, sound output, vibration output) that can be universally applied depending on the situation. The system selects from these multiple functions based on the detected terminal position, ensuring that the appropriate output method is used for each context - screen for detailed information when visible, sound/vibration for alerts during activities.
3Loss of information
If the terminal requires the user to view the screen for information, then detailed information can be conveyed, but it creates safety hazards during activities like driving
Solution Approach 1:
The system uses the detected position of the terminal relative to the user's mouth as feedback to determine the appropriate output method. When the terminal is detected near the mouth, the system infers the user is engaged in an activity and switches to non-visual output, preventing safety hazards. This feedback mechanism allows the system to adaptively prevent harmful situations while maintaining information delivery.

AI summary
To perform information output suitable for the state of a user. A mobile terminal 1 includes an input unit 17, an output unit 18, a response generation unit 53, a position monitoring unit 52, and an output control unit 54. The input unit 17 receives voice input. The output unit 18 displays information, or outputs information by a method other than screen display. The position monitoring unit 52 detects the position of the mobile terminal 1 at the time of the voice input to the input unit 17. The output control unit 54 controls the output unit 18 to display a response to the voice input generated by the response generation unit 53 in the case where, at the time of the output of the response, the position monitoring unit 52 detects the position at the time of the voice input to the input unit 17, and controls the output unit 18 to output the response to the voice input in the case where, at the time of the output of the response, the position monitoring unit 52 detects a position other than the position at the time of the voice input to the input unit 17.
