Pen Input Battery Notification Through Usage-Pattern Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pen-type input devices without Bluetooth communication function provide coarse battery level information, making it difficult to accurately inform users of their remaining usage time, which varies significantly based on individual usage patterns.
Innovation Solution
An information processing apparatus that sets a usage level for the pen-type input device based on multiple usage status information, associates battery voltage levels with time information, and converts this to remaining time for accurate notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a pen-type input device is equipped with Bluetooth communication function, then detailed battery level information (100 levels) can be acquired, but the device size becomes larger and cost increases
Solution Approach 1:
The patent introduces an information processing apparatus as an intermediary that receives coarse battery level information from the pen-type input device and converts it into accurate remaining time estimates. This mediator performs the complex calculations and data processing externally, allowing the pen device itself to remain simple without Bluetooth or detailed battery monitoring hardware.
2Device complexity
If coarse battery level information (3-5 levels) is provided by pen-type input devices without Bluetooth, then device size and cost are reduced, but it becomes difficult to inform users of detailed battery level and remaining usage time
Solution Approach 1:
The patent transforms the battery level information parameter from coarse voltage levels (3-5 levels) into a more meaningful parameter - remaining usage time. By changing the parameter representation from static voltage levels to dynamic time estimates based on usage patterns, the system provides more useful information without requiring the pen device to have complex battery monitoring capabilities.
Solution Approach 2:
The system implements feedback by continuously monitoring usage status and adjusting the remaining time estimates accordingly. The information processing apparatus learns from actual usage patterns and provides increasingly accurate predictions, creating a feedback loop that improves notification precision over time without adding complexity to the pen device.
3Ease of operation
If the same battery level notification is given regardless of usage patterns, then notification simplicity is maintained, but the remaining time estimate becomes inaccurate due to varying usage frequency and duration
Solution Approach 1:
The patent makes the battery level notification dynamic by adjusting it based on usage patterns. Instead of providing static battery level information, the system adapts the remaining time estimates according to how the user actually uses the device. This dynamic approach maintains simplicity for the user while significantly improving accuracy through automated pattern recognition.

AI summary
An information processing apparatus includes: a usage level setting section that sets a usage level indicating a usage status of a pen-type input device using multiple usage status information in which a battery voltage level notified of by the pen-type input device is associated with time information; a remaining time acquisition section that acquires remaining time corresponding to the current battery voltage level by using conversion information corresponding to the set usage level among conversion information in which the battery voltage level is associated with remaining time for each usage level; and a notification section that gives notice of the acquired remaining time.
