Solution Overview

Problem

Existing virtual environment games require complex user interfaces to control user characters, which can lead to reduced user engagement and a less immersive gaming experience.

Innovation Solution

A touch-sensitive display and gesture input device with a pre-defined array of touch-sensitive elements, allowing users to perform continuous sweeps to detect and compare gestures, generating corresponding actions for the user character within the virtual environment, with feedback mechanisms to enhance user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a comprehensive user interface is provided to control user character maneuvers, then control capability is improved, but user interface complexity increases

Engineering Contradiction:

Improvecontrol capabilityVSAvoiduser interface complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The user interface is segmented into two distinct components: a touch-sensitive display for viewing the virtual environment and a separate touch-sensitive gesture input device with a pre-defined array of elements for control. This segmentation allows the control function to be specialized and simplified while maintaining comprehensive control capability through gesture combinations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Traditional mechanical control interfaces (buttons, joysticks, keyboards) are replaced with a touch-sensitive gesture-based interface. Users perform continuous sweep gestures across the touch-sensitive elements, and the system detects and interprets these gestures to generate character actions, eliminating the need for complex physical controls.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a comprehensive user interface is provided to control user character maneuvers, then control capability is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvecontrol capabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Complex mechanical control interfaces are replaced with intuitive touch gestures. The pre-defined array of touch-sensitive elements provides a structured framework that guides users in performing gestures, making the operation easier while maintaining comprehensive control capability through the variety of detectable gesture patterns.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes from discrete button presses to continuous gesture sweeps as the control parameter. By detecting the path, direction, and sequence of touches across multiple elements in the array, the system translates simple user gestures into complex character maneuvers, improving ease of operation.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method for controlling a user character for playing a game within a virtual environment, including providing a user character and virtual environment information on the touch sensitive display to a user; detecting a touch gesture via a touch sensitive gesture input device, the touch gesture formed by a continuous sweep touching at least two touch sensitive elements arranged in the pre-defined array; comparing the detected touch gesture to reference gestures of the user character for playing the game within the virtual environment; and generating an action for the user character within the virtual environment in response to finding a matching reference gesture based on comparison.
