Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch screen interfaces require users to move their hand to select entities from lists, making the process less intuitive and inefficient, especially when dealing with multiple lists or complex options.
Innovation Solution
A touch-sensitive device with a force sensing array, utilizing a quantum tunneling material, allows users to select entities using a single digit (thumb) by applying pressure and scrolling, enabling one-handed operation without changing digits or input devices, with haptic and visual feedback for confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users move their hand across different parts of the screen to select entities from lists, then selection capability is achieved, but operation complexity and time increase
Solution Approach 1:
The screen is divided into multiple selectable regions corresponding to different entities in a list. Each region can be independently selected by applying pressure at that location, eliminating the need to move the hand across the screen. The segmentation allows users to directly access any entity by pressing the corresponding region, significantly reducing selection time and operational complexity.
2Productivity
If conventional touch screen interfaces are used, then basic selection is possible, but operation efficiency decreases when dealing with multiple lists or complex options
Solution Approach 1:
The interface adds a pressure dimension to the traditional two-dimensional touch screen interaction. By detecting the magnitude of pressure applied at different screen locations, the system can distinguish between different selection intents and navigate through multiple lists or options more efficiently. This dimensional addition allows for more complex selections without increasing operational complexity.
3Adaptability or versatility
If multiple buttons or input devices are added to improve selection capability, then functionality increases, but device complexity increases
Solution Approach 1:
The touch screen serves multiple functions: it detects both the location and magnitude of pressure applied by the user. This multi-functional capability allows the same input device to handle various selection scenarios including single-list selection, multi-list navigation, and complex option filtering, without requiring additional buttons or input devices. The universal input mechanism maintains simplicity while providing versatile selection capabilities.

AI summary
A method of selecting an entity from a list of entities, includes providing a manually applied pressure to a touch-sensitive device and activating a range of entities in response to the manually applied pressure. The range of entities includes first and second lists of entities. Scrolling in a first direction enables selection of an entity from the first list of entities and scrolling in a second direction enables selection of an entity from the second list of entities.
