A contactless card using NFC or Bluetooth communication to transmit accommodation information to secondary devices, enabling them to adjust settings and configurations to accommodate users' needs, such as font size, contrast, voice commands, and input methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ATM designs are used, then device functionality is maintained, but users with disabilities cannot access the device due to physical limitations
Solution Approach 1:
The system dynamically adjusts device settings based on real-time detection of accommodation needs. The secondary device monitors user interactions and automatically modifies configuration parameters such as screen orientation, font size, and input methods according to the user's physical capabilities, transforming a static device into an adaptive one.
Solution Approach 2:
The system enables users to self-activate accessibility features through intuitive gestures or patterns without requiring navigation of complex settings menus. Users can independently configure their own accommodation needs by performing simple actions like specific touch patterns or voice commands, eliminating the need for assistant assistance.
2Ease of operation
If accessibility settings are added to devices, then user accommodation is improved, but activation becomes prohibitively difficult for users with limited vision or mobility
Solution Approach 1:
The system introduces an intermediary layer that translates simple user gestures into complex configuration commands. Instead of requiring users to navigate through multiple settings menus, the intermediary interprets intuitive actions (such as specific touch patterns or voice phrases) and automatically applies the appropriate accessibility configurations, bridging the gap between simple user input and complex system responses.
Solution Approach 2:
The system pre-configures accessibility features to be activated through simple gestures rather than requiring users to navigate complex settings menus first. Common accessibility options are prepared in advance and can be instantly activated by performing specific, easy-to-execute actions, eliminating the need for users to understand or navigate through configuration hierarchies.
3Productivity
If touch screens are used for interaction, then device functionality is enhanced, but users with tremors cannot use them without accidentally touching unintended portions
Solution Approach 1:
The system adds temporal and contextual dimensions to touch input recognition. Instead of relying solely on spatial precision, the system analyzes the duration, pressure, and sequence of touches to distinguish intentional inputs from accidental ones. This multi-dimensional analysis allows the system to accurately interpret user intent even when physical precision is limited by tremors or mobility issues.
Solution Approach 2:
The system implements feedback mechanisms that confirm touch recognition before executing actions. When a touch is detected, the system provides visual or haptic feedback to confirm recognition, allowing users to verify that their intended input was correctly interpreted before the action is completed. This feedback loop enables users with tremors to correct unintended touches and maintain accurate interaction.

Data Source
AI summary
A contactless card useful for adjusting the operation, configuration, and/or performance of a secondary device is described. The contactless card is equipped with a communication interface which allows the contactless card to transmit information to the secondary device using NFC signals. The contactless card stores accommodation information related to a physical accommodation desired by the user and transmits that information in the form of an accommodation message to the secondary device after being placed in a NFC field generated by the secondary device. In some embodiments, the contactless card requests an authentication certificate in order to determine a degree of trust prior to sending an accommodation message. In some embodiments, the contactless card may adjust what accommodation information is included in the accommodation message based on the authentication certificate received from the secondary device.
