Solution Overview

Problem

Existing display control systems face challenges in accurately detecting user operations, particularly in scenarios where tremors or unintended touches occur, leading to potential miss-detections and reduced operability.

Innovation Solution

A display control device and method that differentiate between two response periods for operations within distinct areas of an object on a touch panel, allowing for timely execution of functions based on specific duration thresholds, thereby improving operability and minimizing miss-detections by setting a shorter response period for the first area and a longer one for the combined area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a single response period is used for all areas of an object, then the device complexity is reduced, but the measurement precision of user operation intent deteriorates

Engineering Contradiction:

Improvedetection accuracyVSAvoidcontrol logic complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The object's area is segmented into a first area and a second area, each with distinct response periods. The detection section determines which area received the touch operation and applies the corresponding response period, enabling differentiated detection accuracy for different operational contexts without requiring completely separate detection systems.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different response periods are assigned to different areas of the object based on their specific functional requirements. The first area uses a first response period while the second area uses a second response period, allowing each local region to have optimized detection characteristics suited to its purpose.

Inventive Principle:

Principle #3Local quality

2Reliability

If a longer response period is used to avoid miss-detections from tremors, then the reliability of operation detection is improved, but the productivity of the system deteriorates due to delayed response

Engineering Contradiction:

Improveoperation detection reliabilityVSAvoidsystem response speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The object area is divided into first and second areas with different response periods. The first area uses a shorter response period for quick response when precise positioning is achieved, while the second area uses a longer response period to accommodate tremors and prevent miss-detections, thus balancing reliability and productivity based on operational context.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different response periods are applied locally to different areas based on their specific needs. Areas where precise, quick interaction is needed use shorter response periods, while areas where tremor tolerance is needed use longer response periods, optimizing both reliability and productivity for each local context.

Inventive Principle:

Principle #3Local quality

3Productivity

If a shorter response period is used for faster response, then the productivity is improved, but the reliability deteriorates due to increased miss-detections from tremors

Engineering Contradiction:

Improvesystem response speedVSAvoidoperation detection reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The object is segmented into first and second areas, each with optimized response periods. The first area uses a shorter response period to enable fast response and high productivity when the user achieves precise positioning, while the second area uses a longer response period to maintain reliability by tolerating tremors, thus resolving the contradiction between speed and reliability.

Inventive Principle:

Principle #1Segmentation

4Reliability

If the detection threshold is increased to filter out tremors, then the reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveoperation detection reliabilityVSAvoiduser interaction ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of applying a single high detection threshold that would make interaction difficult, the object area is segmented into first and second areas with different response periods. This allows the system to use a longer response period in the second area to accommodate tremors without requiring the user to apply excessive force or maintain prolonged contact, thus maintaining ease of operation while improving reliability.

Inventive Principle:

Principle #1Segmentation

AI summary

A tablet terminal device includes a display and a controller. The controller includes a detection section, a first determination section, a duration measuring section, a second determination section, and an execution section. The detection section detects an operation position where a touch operation is performed. The first determination section determines whether or not the operation position is located within a first area of a first object. The duration measuring section measures a first operation duration during which the detection section keeps detecting the operation position in the first area. The second determination section determines whether or not the first operation duration is equal to or longer than a first response period. The execution section executes a function assigned to the first object when the first operation duration is equal to or longer than the first response period.
