Optical Game Controller Input Surface for Adaptive Buttonless Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game controllers have fixed configurations that do not accommodate varying hand sizes and require physical buttons or joysticks, limiting user comfort and flexibility.
Innovation Solution
A game controller with input control sensors that utilize optical sensors to detect touch, tap, swipe, press, and joystick inputs on a customizable input surface, allowing for adjustable and buttonless operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed configuration controllers are used, then manufacturing cost is reduced, but user comfort and adaptability deteriorate
Solution Approach 1:
The controller transitions from a static fixed configuration to a dynamic reconfigurable system where control elements can be moved to different positions on the controller body, allowing adaptation to different user hand sizes and preferences while maintaining the same physical controller unit
Solution Approach 2:
The controller allows users to modify parameters such as control element position, size, and distribution to suit individual needs, transforming a one-size-fits-all design into a customizable interface that adapts to varying user requirements
2Adaptability or versatility
If physical buttons and joysticks are included, then traditional control functionality is maintained, but controller size increases and flexibility decreases
Solution Approach 1:
Multiple traditional control elements (buttons, joysticks, directional pad) are merged into a single integrated input surface that can detect various input types (touch, tap, swipe, press, joystick input) at different locations, reducing overall controller size while maintaining functional versatility
Solution Approach 2:
The input surface serves multiple functions simultaneously - it can detect touch inputs, tap inputs, swipe gestures, press inputs, and joystick inputs depending on where and how the user interacts with it, replacing the need for separate dedicated control elements
3Ease of operation
If control elements are placed in different fixed locations, then traditional control layout is maintained, but user comfort for varying hand sizes deteriorates
Solution Approach 1:
The controller configuration is made dynamic and adjustable, allowing users to reposition control elements to locations that are comfortable for their specific hand size and playing style, rather than being constrained to fixed predetermined positions

AI summary
Device and process configurations are provided for game controllers. A game controller can include an input control sensor having an input surface and at least one optical sensor to detect input to the input surface. The game controller can also include a controller coupled to the input control sensor to receive game controller input, identify at least one input command, and output a control signal. Input control sensors allow for input based on one or more of touch, tap, swipe, press, pinch and joystick inputs to one or more surfaces of the controller. Input can include a pretouch relative to the input surface, the pretouch including input approaching the input surface and input prior to engagement with a surface. A game controller can present at least one reference point for an input control including illumination and use of a touch screen to detect one or more of heat and pressure.
