Information Processing Shift-Time Control by User Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to accurately balance user convenience and power saving by incorrectly determining the shift time to power saving mode based on the execution count of all processes, leading to prolonged waiting times for users when actual convenience is lower than perceived.
Innovation Solution
An information processing system that detects user operation changes and sets shift times to power saving modes by counting multiple continuous processes as a single process, using an index value based on process execution counts in different modes, and employing a cumulative exponential distribution function to optimize shift times.

Engineering Contradiction Analysis
1Measurement precision
If all processes performed in executable mode are counted as execution counts for executable mode, then the determined convenience is much higher than the actual user feeling, but the shift time to power saving mode is set less than appropriate value, causing users to wait long for return from power saving mode
Solution Approach 1:
The patent segments continuous processes performed by the same user into only the first process being counted, while subsequent continuous processes are excluded from the execution count. This segmentation allows the system to accurately distinguish between processes that truly reflect user convenience needs versus routine continuous operations, thereby setting appropriate shift times to power saving mode without causing excessive waiting time.
2Loss of energy
If the shift time to power saving mode is shortened for slightly lower convenience and higher power saving, then power saving of the apparatus is improved, but the user convenience degrades as the apparatus is often in power saving mode requiring long waiting time
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors process execution patterns and user behavior, then adjusts the shift time to power saving mode based on this feedback. By counting only the first process of continuous processes and excluding subsequent ones, the system learns actual user convenience needs and dynamically optimizes the shift time to balance power saving with user convenience, preventing both excessive power consumption and excessive waiting time.

AI summary
An information processing system includes a processor for an apparatus having an executable mode and one or more types of power saving mode and setting a shift time from the executable mode to the power saving mode, the executable mode being a mode in which execution of a process is ready, the processor being configured to: detect change of a user who operates the apparatus; obtain an index value based on counts of execution of processes in the respective modes in the apparatus, and set the shift time based on the obtained index value; and, in the setting, count, as a single process, a plurality of processes in the count for the mode in which the first process of the plurality of processes is performed, the plurality of processes being performed continuously in a state in which the change is not detected.
