Camera Activation via Posture and Grasping Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with cameras lack improved operability, particularly in automatically activating the camera based on changes in device posture and user interaction.
Innovation Solution
Incorporating an acceleration sensor to determine the device's posture and a grasping form recognizing unit to assess user interaction, allowing the activation control unit to automatically activate the camera when the device is upright and not being covered, using sensors like illuminance, touch, or pressure sensors for accurate recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera is automatically activated based on posture detection, then the operability is improved, but the camera may be accidentally activated when the device is placed upright without user intent
Solution Approach 1:
The patent combines multiple sensing mechanisms (acceleration sensor for posture detection, grasping form recognition for user intent detection) into a unified camera activation control system. This merging allows the system to cross-validate signals before triggering camera activation, thereby improving reliability while maintaining ease of operation.
Solution Approach 2:
The system implements feedback by continuously monitoring both posture changes and grasping form patterns, then using this information to dynamically control camera activation. The feedback loop ensures that camera activation occurs only when both posture and grasping form conditions are satisfied, preventing accidental activation while maintaining user-friendly operation.
2Reliability
If multiple sensors are used to accurately recognize user intent, then the reliability of camera activation control is improved, but the device complexity increases
Solution Approach 1:
The acceleration sensor serves multiple functions: it detects device posture for activation control, monitors device movement patterns for grasping form recognition, and provides data for both immediate and delayed activation scenarios. This multi-functionality reduces the need for separate dedicated sensors, thereby limiting the increase in device complexity while maintaining high reliability.
Solution Approach 2:
The system uses the device's existing acceleration sensor data for multiple purposes including posture detection, movement pattern recognition, and grasping form analysis. By making the acceleration sensor serve itself across multiple detection tasks, the patent avoids adding redundant sensors, thus controlling device complexity while achieving reliable user intent recognition.

AI summary
An electronic device includes a camera; an acceleration sensor that detects an acceleration applied to a housing; a posture determining unit that determines a posture of the housing based on a value detected by the acceleration sensor; and an activation control unit that activates the camera when the posture determining unit determines that the posture of the housing becomes an upright posture.
