ATM Display Screen Glare Reduction and Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service devices like ATMs and kiosks face issues with glare from sunlight and exposure to unauthorized access, leading to usability problems and potential fraud when operated outdoors.
Innovation Solution
The implementation of electronically controllable display screens with sensors to detect sunlight and unauthorized observers, along with mechanisms such as visors, hinged anti-glare covers, and computer-controlled actuators to minimize glare and protect user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ATM is operated outdoors, then accessibility and convenience are improved, but the display screen becomes illuminated by direct sunlight preventing correct operation
Solution Approach 1:
The display screen is mounted on an electronically controllable mount that can dynamically adjust its orientation and position. The system uses sensors to detect sunlight direction and automatically repositions the screen to minimize glare, allowing the ATM to be operated outdoors without sunlight interference blocking the display.
2Ease of operation
If the ATM is operated outdoors, then accessibility and convenience are improved, but the system becomes susceptible to fraud through unauthorized observation
Solution Approach 1:
The display screen mounted on an electronically controllable mount can dynamically adjust its orientation to face only the authorized user. Sensors detect the position of unauthorized observers and reposition the screen accordingly, ensuring that sensitive information like PINs and account details are visible only to the legitimate user even when operated outdoors.
Solution Approach 2:
The controllable mount acts as an intermediary between the display screen and unauthorized observers. By physically positioning the screen away from line-of-sight of potential eavesdroppers while maintaining visibility for the user, the mount mediates the conflict between outdoor accessibility and privacy protection.
3Reliability
If sensors and controllable mounts are added to the ATM, then visibility and security are improved, but device complexity increases
Solution Approach 1:
The electronically controllable mount serves multiple functions: it adjusts the display orientation to optimize visibility for the user, positions the screen to block unauthorized observers, and can integrate with other ATM components. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in overall system complexity despite adding sensor and actuator capabilities.

AI summary
A method for minimizing glare and/or increasing privacy for a user of a self-service device is provided. The method may include mechanical means such as a fixed visor and/or hood or a user operated hinged glare reducing overlay screen. The method may further include as using sensors that detect the user's eyes and other sensors to detect a source of light that produces glare. Information from these sensors may be sent to a computer controlled system that operates system of actuators. The actuators are operated by the computer in response to sensor inputs to adjust the screen angle relative the user to minimize glare for that user and/or increase privacy from surreptitiously observing eyes or cameras.
