Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Handheld controllers provide limited input options compared to keyboards and mice, hindering efficient text entry in information handling systems.

Innovation Solution

Mapping control stick positions on a handheld controller to characters and using button inputs to select characters, with graphical indications to guide user entry, and employing multiple control sticks for character selection and case/Unicode variant adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a keyboard and mouse combination is used, then a wide array of selectable inputs is provided, but the device is less ergonomic for mobile use and away-from-desk situations

Engineering Contradiction:

Improveinput optionsVSAvoidergonomic portability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The handheld controller is designed to perform multiple functions: it provides directional control through control sticks, text input through character mapping to stick positions, and other command inputs through buttons. This multi-functionality allows a single device to replace both keyboard and mouse in many scenarios, providing versatility while maintaining ergonomic portability

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a handheld controller is used, then ergonomic portability and mobile usability are improved, but the number of selectable input options is reduced

Engineering Contradiction:

Improveergonomic portabilityVSAvoidinput options

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The text input function is segmented from traditional keyboard input and reimagined through spatial mapping. Each position of the control stick corresponds to specific character(s), allowing text input through directional movement rather than discrete key presses. This segmentation enables the handheld controller to provide keyboard-like functionality while maintaining its ergonomic advantages

Inventive Principle:

Principle #1Segmentation

3Productivity

If control stick positions are mapped to characters for text entry, then text entry speed and efficiency are improved, but the device complexity increases

Engineering Contradiction:

Improvetext entry speedVSAvoidinput mapping complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system provides visual feedback by displaying which character(s) are currently selected based on control stick position. This feedback mechanism helps users understand the mapping relationship and makes the increased functionality feel more intuitive, reducing the perceived complexity while maintaining high text entry speed

Inventive Principle:

Principle #23Feedback

AI summary

An information handling system may receive a first input indication from a first control stick of a handheld controller, wherein the first input indication indicates that the first control stick is in a first position, receive a second input indication from a first button of the handheld controller, wherein the second input indication indicates that the first button is pressed while the first control stick is in the first position, and determine that the first input indication corresponds to a first character in response to receipt of the first input indication. The information handling system may then select the first character based on the determination that the first input indication corresponds to the first character and receipt of the second input indication.
