Solution Overview

Problem

Existing information processing devices require users to input information about their dominant hand, which can be inconvenient and burdensome.

Innovation Solution

The device determines the user's dominant hand based on positional relationship information, such as direction and distance between objects, without requiring explicit input, and adjusts the display positions of objects to facilitate intuitive interactions, like collision-based operations, by using a dominant hand determination unit and initial display position setting mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device requires users to input information about their dominant hand, then the display layout can be optimized for the user's dominant hand, but the user convenience deteriorates due to the additional input task

Engineering Contradiction:
Improvedisplay layout optimizationVSAvoiduser input task
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically determines the user's dominant hand by analyzing the positional relationships and interaction patterns between multiple objects on the display screen, eliminating the need for users to manually input this information. The device serves itself by inferring user characteristics from usage behavior.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors and analyzes the positional relationships between objects and user interaction patterns, using this feedback to automatically adjust and optimize the display layout according to the determined dominant hand, creating a dynamic adaptation cycle.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the device automatically determines dominant hand from interaction patterns, then user convenience is improved by eliminating input tasks, but the measurement precision of dominant hand determination may deteriorate

Engineering Contradiction:
Improveautomatic dominant hand determinationVSAvoiddominant hand determination accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary analysis of positional relationships between multiple objects and user interaction patterns before making the dominant hand determination, gathering sufficient data in advance to ensure accurate inference of user characteristics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system analyzes dominant hand characteristics not just from single interactions but from multi-dimensional positional relationships between multiple objects and their spatial arrangements, adding dimensional depth to the analysis for more accurate determination.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the display layout is adjusted based on dominant hand determination, then user convenience is improved, but the device complexity increases due to additional processing mechanisms

Engineering Contradiction:
Improveadaptive display layoutVSAvoidprocessing mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system uses a multi-functional processing mechanism that handles both the dominant hand determination and the display layout optimization through integrated analysis of positional relationships, allowing one system to perform multiple functions rather than requiring separate dedicated components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the dominant hand determination process with the display layout adjustment process by analyzing positional relationships between objects as a unified operation, combining what could be separate functions into a single integrated processing flow.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

To provide an information processing device capable of enhancing convenience of a user using the information processing device by considering a dominant hand, habit, or the like, of the user without imposing on the user a task of inputting information of the user's dominant hand, habit, the like. In a case where it is determined that a user's designated position is included in a determination area corresponding to an object, the object is moved in accordance with movement of the designated position. In a case where at least one of one object and another object moves, processing relevant to the objects is executed based on a result of collision determination executed with respect to the objects. A second processing executing unit (64) executes predetermined processing based on a positional relationship between one object or one designated position and another object or another designated position in a case in the past in which it is determined that the one designated position is included in the determination area corresponding to the one object and the other designated position is included in the determination area corresponding to the other object.
