Handheld Controller Color Picker for Multi-Property Selection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current handheld controllers lack efficient methods for users to intuitively select and adjust multiple properties of virtual objects, such as hue, tint, tone, and brightness, on a display, limiting user experience and interaction capabilities.

Innovation Solution

Implementing a handheld controller with input devices like joysticks or trackpads that have defined regions for selecting and adjusting properties, allowing users to interact with a color picker by moving the input device within specific areas to modify properties like hue, tint, tone, and brightness, with the color picker updating in response to user inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a keyboard and mouse are used for property selection, then input precision is adequate, but the betting experience becomes cumbersome and tedious

Engineering Contradiction:

Improvebetting experienceVSAvoidtime to select properties

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical input devices (keyboard and mouse) with a handheld controller that uses motion sensing technology. The controller detects wrist movements and translates them into property selections, substituting the mechanical clicking and typing actions with motion-based control. This substitution maintains input precision while dramatically improving ease of operation and reducing the time required to select properties.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If motion sensing technology is implemented, then ease of operation improves, but device complexity increases

Engineering Contradiction:

Improveproperty selection convenienceVSAvoidcontroller system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The handheld controller is designed to serve multiple functions beyond property selection. It can control bet sizing, manage game settings, and interface with various betting games. By making the device universal and multi-functional, the complexity is justified through increased versatility, and the same hardware platform supports multiple operations without requiring separate specialized devices for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If traditional input devices are used, then device complexity remains low, but productivity in property selection decreases

Engineering Contradiction:

Improveproperty selection speedVSAvoidinput system complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The motion sensing controller enables preliminary action by allowing players to pre-select properties and prepare bets more quickly through intuitive motion gestures. The system can detect and register selections before the betting deadline, enabling faster overall productivity in the betting process. The motion-based interface allows for rapid successive selections without the mechanical limitations of keyboard typing or mouse clicking.

Inventive Principle:

Principle #10Preliminary action

AI summary

Described herein are, among other things, techniques to enable a user to navigate a color picker or other graphical-user-interface (GUI) tool using an input device of a handheld controller. For example, a user may operate a color picker presented on a display by pressing upwards on a joystick to activate selection of hue. In some instances, the user may also operate the joystick to alter a tint, tone, shade, or brightness.
