Dynamic Graphical Interface Scaling by Viewing Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional graphical user interfaces on high-resolution displays face difficulties in usability due to inputs and text being difficult to discern when viewing distance increases slightly, especially in all-in-one large touchscreen computers.
Innovation Solution
A customizable and adaptive system that adjusts display settings and application software settings based on the user's viewing distance using a distance sensing device, allowing dynamic modification of display modes to enhance readability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If display resolution is increased for high-resolution displays, then image quality and detail are improved, but inputs and text become difficult to discern when viewing distance increases
Solution Approach 1:
The system dynamically adjusts display settings including resolution, font size, and input element size based on detected viewing distance. When the user moves closer, the system increases resolution for detailed viewing; when the user moves away, the system decreases resolution and increases element sizes to maintain usability, creating a dynamic adaptation to user position.
Solution Approach 2:
The system changes multiple display parameters simultaneously based on viewing distance measurements. It adjusts resolution, font size, input element size, and other display settings as a coordinated set of parameter changes, allowing the display to optimize both image quality and usability for different viewing distances.
2Ease of operation
If viewing distance increases, then user comfort and posture are improved, but readability and discernibility of inputs and text deteriorate
Solution Approach 1:
The system uses a distance sensing device to continuously monitor viewing distance and provides feedback to the display control system. Based on this feedback, the system automatically adjusts display parameters to maintain readability and information discernibility while allowing the user to maintain comfortable viewing distances without straining to see small text and inputs.
3Device complexity
If display settings are made static and fixed, then system complexity is reduced, but adaptability to different viewing distances is lost
Solution Approach 1:
The system performs self-adjustment of display settings based on automatic detection of viewing distance. The distance sensing device and control system work together to automatically modify display parameters without requiring user intervention, enabling the system to adapt to different viewing distances while maintaining relatively simple operation for the user.

AI summary
Methods, apparatus, systems are disclosed for altering displayed content on a display device responsive to a user's proximity. In accord with an example, a computing system includes a display, a sensor to output a signal, machine readable instructions, and programmable circuitry to be programmed in accordance with the instructions to determine a distance between the compute system and a person based on the signal, and cause a size of at least one object to be presented on the display to be adjusted based on the distance.
