Gaze Detection for Power Mode Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices face challenges in efficiently transitioning to energy-saving modes, as they often require user intervention or rely on inaccurate timers, leading to unnecessary power consumption and incorrect detection of user intent.
Innovation Solution
An information processing apparatus equipped with a gaze detection unit that shifts from a normal mode to an energy-saving mode when it detects a lack of user gaze, using a controller to manage this transition based on predetermined thresholds and sampling cycles to ensure accurate and timely mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the device uses timer-based detection to switch to energy-saving mode, then automation is improved, but measurement precision deteriorates leading to false triggers and incorrect detection of user intent
Solution Approach 1:
The patent replaces timer-based detection with gaze detection technology that uses cameras and image processing to detect user eye movements and gaze direction. This substitution of the detection mechanism fundamentally improves measurement precision by directly observing user intent through gaze patterns rather than relying on indirect timer-based assumptions about user absence.
2Measurement precision
If the device requires user intervention to switch modes, then measurement precision is improved through direct user input, but ease of operation deteriorates due to additional user actions required
Solution Approach 1:
The system performs self-service by automatically detecting user gaze and autonomously switching between operational modes without requiring explicit user commands. The gaze detection unit monitors user attention, and the controller automatically transitions to energy-saving mode when the user is determined to be away, eliminating the need for manual mode switching while maintaining accurate user intent detection.
3Reliability
If the device remains in normal mode continuously, then reliability is improved by ensuring readiness for user interaction, but use of energy deteriorates due to constant power consumption
Solution Approach 1:
The patent implements dynamic mode switching that adapts the device's operational state based on real-time gaze detection. The system transitions between normal mode and energy-saving mode depending on user presence and attention, optimizing the balance between reliability and energy consumption by being ready when needed and conserving energy when the user is absent.
Solution Approach 2:
The gaze detection unit operates periodically to monitor user presence, enabling the device to rhythmically switch between operational states. This periodic detection allows the system to maintain readiness during active use while transitioning to energy-saving mode during periods of user absence, creating an optimized cycle of power consumption that responds to actual usage patterns.

AI summary
An information processing apparatus includes a controller that controls the information processing apparatus to shift from a first state concerning electric power consumption to a second state in which electric power consumption is smaller than the electric power consumption in the first state; and a gaze detection unit that detects a gaze toward the information processing apparatus. The controller controls the information processing apparatus to shift from the first state to the second state in a case where the gaze detection unit has not detected a gaze toward the information processing apparatus.
