Button Context Locking for Eyes-Free Public Safety Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety personnel face challenges in operating mobile devices with touchscreens during critical situations, as they require visual attention and cognitive resources, leading to potential distractions and incorrect operations.
Innovation Solution
A device with buttons mapped to specific functions, allowing activation of functions within a threshold time period after receiving an electronic communication, either using the source contact or independently, to enable eyes-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touchscreen operation is used, then device functionality is improved, but visual attention and cognitive resources are required, leading to distractions and potential incorrect operations
Solution Approach 1:
The patent replaces touchscreen operation (visual-cognitive interface) with physical button presses (tactile-motor interface). Buttons are strategically positioned on the device housing to allow operation without visual attention, substituting the mechanical touchscreen interaction with simpler tactile feedback-based physical controls.
2Adaptability or versatility
If touchscreen operation is used, then device functionality is improved, but visual attention is required, causing distractions in critical situations
Solution Approach 1:
The patent segments the user interface into distinct functional buttons positioned at different locations on the device. Each button corresponds to specific functions (e.g., communication functions, navigation functions), allowing users to perform complex operations through simple, segmented tactile inputs without needing to visually navigate complex menus.
3Reliability
If buttons are added for eyes-free operation, then operational reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functional buttons that can perform different operations depending on the context. For example, buttons can initiate communications with different contacts based on recently received messages, or perform navigation functions, reducing the need for separate dedicated buttons for each function while maintaining operational reliability.
Data Source
AI summary
A device and method for locking in button context based on a source contact of an electronic communication is provided. An electronic communication is received, via a communication interface, from a source contact. A controller detects that a button, of one or more buttons external to the device, has been activated, each of the one or more buttons mapped to activation of respective functions. The controller identifies a respective function mapped to the button. When the button is activated within a threshold time period after receiving the electronic communication, the controller performs the respective function using the source contact from which the electronic communication was received. When the button is activated after the threshold time period, the controller performs the respective function independent of the source contact.
