Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer-based user interfaces are complex and confusing, lacking adequate solutions to determine user interest in digital content effectively.
Innovation Solution
A device with a processor, camera, and display that receives input from the camera to detect changes in pupil dilation, determining user interest in content presented on the screen and taking actions such as liking or disliking content, or prompting assistance, based on observed pupil changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex computer-based user interfaces are used to determine user interest, then more features and controls are available, but the interface becomes more confusing and harder to use
Solution Approach 1:
The system automatically detects user interest through pupil dilation analysis and performs actions (liking, disliking, skipping content) without requiring explicit user input. The interface serves itself by interpreting physiological responses, eliminating the need for complex interaction controls while maintaining high adaptability to user preferences.
Solution Approach 2:
The patent replaces mechanical interaction mechanisms (buttons, sliders, menus) with a physiological detection system that measures pupil dilation. This substitution transforms the interaction model from active user control to passive physiological response measurement, simplifying the interface while enhancing versatility.
2Reliability
If traditional explicit user input methods are used, then user actions are clear and unambiguous, but the interaction process becomes more complex and time-consuming
Solution Approach 1:
The system replaces mechanical input devices (keyboard, mouse, touchscreen) with a physiological sensing system that captures pupil dilation through the camera. This substitution provides reliable interest detection while reducing interaction system complexity by eliminating multiple input modalities.
Solution Approach 2:
The patent introduces pupil dilation as an intermediary physiological signal that mediates between user intent and system action. Instead of direct mechanical input, the system uses this biological intermediary to infer user interest, providing reliable detection with simpler interaction requirements.
3Productivity
If manual user actions are required to express interest in content, then user control is precise, but the process becomes more time-consuming and less efficient
Solution Approach 1:
The system performs content interaction actions automatically based on detected pupil dilation, serving itself without requiring user time for manual operations. The interface self-adjusts by liking, disliking, or skipping content based on real-time physiological feedback, dramatically improving productivity while eliminating interaction time loss.
Solution Approach 2:
The system performs interest-expression actions in advance of explicit user commands by detecting pupil dilation changes that occur naturally during content consumption. This preliminary action captures user interest moments before the user would manually express them, increasing efficiency without time loss.

AI summary
In one aspect, a device may include at least one processor, a camera accessible to the at least one processor, and storage accessible to the at least one processor. The storage may include instructions executable by the at least one processor to receive input from the camera and to determine, based on the input from the camera, that a change in the dilation of a user's pupils has occurred. The instructions may also be executable to perform at least one action at a device based on the determination, where the at least one action may be related to the user's interest in at least a portion of content presented using the device.
