Solution Overview

Problem

Conventional information processing apparatuses with touch panels face inefficiencies in operability and power consumption due to uniform optimization methods that do not account for varying application-specific requirements, leading to increased CPU load and power usage across different applications.

Innovation Solution

The implementation of profile information for each application program to optimize touch panel settings, including sensitivity, confirmation times, and reporting rates, which are dynamically updated based on the active-state application, allowing for tailored performance and power management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If uniform optimization parameters are set for the touch panel to handle all application programs, then the touch panel can support all applications, but CPU resources and electric power are significantly consumed

Engineering Contradiction:
Improvetouch panel compatibilityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The touch panel parameters are made dynamic by switching between different parameter sets based on the active application. The system dynamically adjusts sensitivity, reporting rate, and confirmation times according to which application is currently running, rather than maintaining fixed uniform parameters. This resolves the contradiction by enabling high adaptability when needed while conserving power when maximum performance is not required.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the operational parameters of the touch panel based on the active application state. Different applications receive different parameter configurations (e.g., higher sensitivity for gaming, lower reporting rates for text input), allowing the system to maintain versatility across applications while optimizing power consumption for each specific use case.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If uniform optimization parameters are set for the touch panel to handle all application programs, then the touch panel can support all applications, but the processing load of the CPU increases

Engineering Contradiction:
Improvetouch panel compatibilityVSAvoidCPU processing load
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system dynamically switches between different parameter sets based on the active application, reducing the need for continuous high-level processing. By pre-configuring application-specific parameters, the CPU avoids performing complex real-time calculations for parameter optimization, thereby reducing processing load while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Parameter sets are prepared in advance for different application types. When an application becomes active, the corresponding pre-configured parameter set is applied without requiring complex real-time processing. This preliminary preparation reduces the CPU processing load during operation while maintaining the ability to support multiple applications.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If high sensitivity and high reporting rate are maintained for all applications, then the operability is improved, but power consumption increases

Engineering Contradiction:
Improvetouch panel operabilityVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

Different regions of the touch panel or different applications receive different sensitivity and reporting rate settings based on their specific needs. For example, gaming applications may receive high sensitivity settings while messaging applications use lower settings, optimizing operability locally for each use case while reducing overall power consumption.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes sensitivity and reporting rate parameters based on the active application. High sensitivity and high reporting rates are applied only when necessary for specific applications, rather than being maintained uniformly across all applications. This selective parameter adjustment improves operability where needed while conserving power elsewhere.

Inventive Principle:
Principle #35Parameter changes
