Stationary State Detection for Implicit User Interface Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional man-machine interfaces require explicit user attention and action, making them disruptive and cumbersome, as they rely on specific inputs or gestures for command detection, lacking natural and implicit interaction methods.
Innovation Solution
An apparatus equipped with a proximity sensor and motion sensor that detects a user's presence and stationary state, allowing for implicit interaction by monitoring movement and providing responses based on stillness detection, enabling unconscious control of external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional input devices (keys, buttons, mouse, touch screen, microphone) are used for command detection, then specific user commands can be received, but user attention and consciousness are required making the interface disruptive and cumbersome
Solution Approach 1:
The system performs self-detection of user presence and stationary state without requiring explicit user input. The apparatus autonomously monitors its own motion state through motion sensors and determines when a user is present and stationary, enabling implicit control without traditional input devices
Solution Approach 2:
The patent replaces mechanical input devices (keys, buttons, mouse, touch screen) with a motion-based detection system using accelerometers and gyroscopes to sense user presence and stationary state, substituting physical interaction with implicit motion detection
2Reliability
If explicit user input is required for control, then precise command detection is achieved, but the interface becomes cumbersome and requires continuous user attention
Solution Approach 1:
The system performs preliminary detection of user presence and stationary state before executing control functions. By detecting the stationary state in advance, the system prepares to receive or execute commands without requiring continuous user attention or explicit input actions
3Adaptability or versatility
If traditional input devices are used, then specific commands can be explicitly controlled, but the interaction method becomes disruptive and annoying
Solution Approach 1:
The motion sensor system serves multiple functions: detecting user presence, determining stationary state, and enabling implicit control. This universal detection mechanism replaces multiple specialized input devices while maintaining control versatility through a single integrated system

AI summary
Methods, apparatuses and systems for interfacing with a user based on the detection of a state, such as a stationary state, of the apparatus are described herein. An example method of interfacing with a user includes: detecting a user in proximity of an apparatus; entering a first mode of the apparatus responsive to detection of the user in proximity; receiving motion data from one or more sensors of the apparatus responsive to movement of the apparatus; and detecting a stationary state of the apparatus based on the motion data; and entering a second mode responsive to detection of the stationary state.
