Interactive Surface Collision Warning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As interactive glass surfaces become more widespread, there is a growing risk of users or objects colliding with them, leading to potential injuries and damage, as these surfaces are often not visible or recognized in time, especially in environments like hospitals or homes where accidents can occur.
Innovation Solution
A system that uses cameras, sensors, and location positioning systems to detect the trajectory of a person or object approaching an interactive surface, generating notifications such as opacity changes, messages, sounds, and vibrations to alert users of impending collisions, adjusting intensity based on the likelihood of impact.

Engineering Contradiction Analysis
1Illumination intensity
If interactive glass surfaces are made transparent to maintain aesthetic appeal and functionality, then visibility and user interaction are improved, but the risk of collision and injury increases
Solution Approach 1:
The system performs preliminary detection of approaching objects using cameras and sensors before collision occurs. Trajectory analysis is conducted in advance to predict potential collisions, allowing the system to issue warnings and adjust surface properties proactively rather than reactively.
Solution Approach 2:
The transparent display surface acts as an intermediary element that can dynamically change its optical properties. When collision risk is detected, the surface transitions from transparent to opaque or displays visual warnings, serving as a mediator between the invisible glass and the approaching object to prevent harm while maintaining normal transparency during safe conditions.
2Reliability
If notification intensity is increased to improve collision warning effectiveness, then safety awareness is enhanced, but user annoyance and distraction increase
Solution Approach 1:
The notification system dynamically adjusts its intensity and type based on real-time trajectory analysis and proximity measurements. As objects approach closer to the interactive surface, warning intensity increases progressively. Once objects move away or change trajectory, notifications are reduced or eliminated, creating a dynamic response that matches the actual risk level.
Solution Approach 2:
The system changes multiple parameters of notifications including brightness levels, color intensity, sound volume, and vibration strength based on the detected trajectory and proximity of approaching objects. These parameter adjustments ensure warnings are sufficiently intense to be noticed when needed while minimizing unnecessary disturbances during normal operation.
Data Source
AI summary
A system for providing awareness of an interactive surface is disclosed. The system may include a processor that is communicatively linked to an interactive surface. The processor may determine a position and a velocity of an object that is within range of the interactive surface based on one or more of media content, vibrations, air movement, sounds and, global positioning data associated with the object. Additionally, the processor may determine if the object has a trajectory that would cause the object to collide with the interactive surface based on the information associated with the object. If the processor determines that the object has a trajectory that would cause the object to collide with the interactive surface, the processor can generate a notification.
