Presence Detection Mode Switching to Prevent Unnecessary Bootups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems transition to standby state based on triggers other than person detection, leading to potential unnecessary bootups due to false positives or temporary absences, which can result in power inefficiencies and unwanted system reactivations.
Innovation Solution
An information processing apparatus and method that employs a sensor to detect objects within a range, transitioning through multiple detection modes based on presence or absence of a person, adjusting detection times and modes to prevent unnecessary bootups by changing detection times and modes based on specific triggers and user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system maintains high detection performance during waiting time to detect person leave, then person detection accuracy is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by switching between two detection modes: a first detection mode with high detection performance during waiting time to detect person leave, and a second detection mode with low detection performance during normal standby state. This dynamic switching resolves the contradiction by adapting detection performance to the specific operational phase, maintaining high accuracy only when necessary while reducing power consumption during stable states.
2Reliability
If the system uses a waiting time before transitioning to standby state, then false positive detection is reduced, but response time to enter standby state increases
Solution Approach 1:
The patent applies preliminary action by implementing a waiting time period after person leave detection before transitioning to standby state. During this waiting time, the system continues operating in the first detection mode to confirm whether the person has truly left. This preliminary confirmation action prevents false positive transitions to standby state, improving detection reliability at the cost of a controlled time delay.
3Speed
If the system transitions to standby state based on non-person-detection triggers, then system responsiveness is improved, but unnecessary bootup occurs due to false person detection
Solution Approach 1:
The patent applies feedback by continuously monitoring detection results during the waiting time period even after transitioning to standby state. If person detection occurs during this period, the system receives feedback and transitions back to the first detection mode, preventing unnecessary bootup. This feedback mechanism ensures that standby state transitions based on non-person-detection triggers do not lead to unstable or incorrect system states.

AI summary
The present invention is to prevent unnecessary bootup by person detection processing when the transition to a standby state is made with a trigger other than that of detecting the leave of a person. An information processing apparatus performs detection processing having a first detection mode to make a transition to a second detection mode when it is determined that a person becomes absent, the second detection mode to return to the first detection mode when the motion of an object is detected during a certain period of time, or to make a transition to a third detection mode when the motion of an object is not detected during the certain period of time, and the third detection mode to detect an object with low power consumption, wherein when an operating state of a system is controlled to a first operating state or a second operating state with power consumption lower than the first operating state based on a processing trigger other than the detection processing though it is determined in the detection processing that a person is present in the first detection mode, a detection time in the second detection mode is changed to 0, or the transition of the operating state of the system to the third detection mode is made without waiting for the certain period of time when it is determined that the person becomes absent in the first detection mode.
