Virtually Divided Trackpad for Simultaneous Move and Rotate Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trackpads offer limited efficiency and ergonomic comfort in tasks requiring complex inputs such as simultaneous movement and rotation of on-screen objects, as they operate on a one-function-at-a-time basis.
Innovation Solution
A virtually divided trackpad with separate input recognition algorithms and haptic feedback mechanisms for each functional area, allowing simultaneous and independent control of movement and rotation of digital objects using both hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional single-function trackpad is used, then the device structure remains simple, but the productivity and operational efficiency deteriorate due to inability to perform simultaneous complex inputs
Solution Approach 1:
The trackpad surface is divided into multiple independent functional areas, each capable of detecting and processing different types of inputs simultaneously. This segmentation allows one area to handle movement control while another handles rotation or other functions, thereby improving productivity without requiring multiple separate devices.
Solution Approach 2:
Each functional area on the trackpad is designed to perform multiple input functions independently. The trackpad can simultaneously interpret different gestures (tapping, swiping, pinching) on different areas, enabling multi-functional operation from a single device surface, thus enhancing productivity while maintaining device integration.
2Ease of operation
If a traditional trackpad operates on a one-function-at-a-time basis, then the device complexity remains low, but the ease of operation deteriorates for tasks requiring simultaneous complex inputs
Solution Approach 1:
By dividing the trackpad into distinct functional zones, each zone can be optimized for specific input types (e.g., one zone for panning, another for zooming). This segmentation makes complex tasks easier to perform by allowing intuitive simultaneous operations across different zones, improving ease of operation.
Solution Approach 2:
Different regions of the trackpad surface are assigned different functional qualities or sensitivities. For example, certain areas may be more responsive to light touches while others detect pressure, or different gesture types. This local differentiation enhances ease of operation by providing specialized control zones for different tasks.
