Camera Lens Cover Dynamics for Privacy and Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable terminals with cameras face challenges in maintaining a consistent angle of view due to user posture and environment, and there is a concern about others being aware of the camera's presence.
Innovation Solution
An information processing apparatus with an acquisition unit to gather activity information and a control unit to adjust the camera's capture angle based on the user's situation, using sensors like gyro and acceleration sensors to optimize the angle of view and hide the lens when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera lens is always exposed for photographing, then the angle of view can be adjusted according to user situation, but others can notice the camera presence and feel uncomfortable
Solution Approach 1:
The patent applies the dynamics principle by making the lens cover movable rather than fixed. The lens cover dynamically opens and closes based on the detected user situation (behavioral state). When the user is in a state suitable for photographing, the lens cover opens to allow capture; when not, it closes to conceal the camera. This dynamic adjustment resolves the contradiction by enabling angle of view adaptation when needed while maintaining privacy when photographing is not required.
2Object-affected harmful factors
If the lens cover is closed to hide the camera, then privacy is protected, but the angle of view cannot be adjusted for different user situations
Solution Approach 1:
The lens cover is designed as a dynamic component that can transition between closed and open states. The control unit automatically opens the lens cover when the acquisition unit detects that the user is in an appropriate behavioral state for photographing, thereby enabling angle of view adjustment. When the user situation changes or photographing is not needed, the lens cover closes to protect privacy. This dynamic behavior allows the system to alternately satisfy both privacy protection and angle of view adaptability requirements.
3Measurement precision
If the camera is equipped with multiple sensors for detecting user situation, then the capture angle can be precisely controlled, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing the sensor system to serve multiple functions simultaneously. The same sensors (acceleration sensor, gyro sensor, etc.) are used not only for detecting user behavioral state to control the lens cover and angle of view, but also for determining photographing timing and other camera operations. This multi-functional use of sensors reduces the need for separate dedicated components, thereby controlling device complexity while maintaining precise user situation detection capability.
