Overview

Определитель купюр is a specialized Android application designed to assist blind and visually impaired individuals in identifying the denomination of banknotes. Developed by Sensor-Tech, the app serves as a critical accessibility tool, enabling users to independently manage financial transactions without relying on others. Its primary function is to recognize banknote values using the smartphone’s camera and deliver results through multiple sensory channels: visual (large contrasting numbers), audio (voice assistant), and tactile (vibrations).

This multi-modal feedback system ensures usability across different levels of visual impairment, including deaf-blind users who can rely on vibrations and screen reader integration. The app is not intended for counterfeit detection or use with game currency, focusing solely on accurate denomination identification. Real-world scenarios include shopping, public transport payments, and handling cash at home or in financial institutions.

The software is optimized for everyday use, supporting seamless operation in low-light conditions and varied environments. Sensor-Tech has prioritized accessibility, ensuring compatibility with Android’s built-in screen reader (TalkBack) and Braille displays. This makes the app a vital resource for promoting independence and confidence in financial interactions.

Key Features & Capabilities

• Multi-Modal Feedback System: The app delivers results through visual, audio, and tactile feedback, allowing users to receive information in the modality that best suits their needs.
• Banknote Recognition via Camera: Users simply point the smartphone’s camera at a banknote; the app automatically begins recognition upon screen touch.
• Compatibility with Accessibility Tools: Fully supports TalkBack and Braille displays, ensuring usability for blind and deaf-blind users.
• Large Contrasting Visual Display: For users with partial vision, the app highlights denomination numbers in high-contrast colors for easy reading.
• Real-Time Audio Output: A voice assistant announces the banknote value immediately after recognition, reducing response time.
• On-Screen Tactile Feedback: Vibrations are triggered upon successful recognition, providing a physical cue for confirmation.

These features work together to create a reliable and intuitive user experience. For example, a visually impaired user can quickly verify a 100-ruble note while shopping, using audio feedback to confirm the amount without needing assistance. In public settings, the app’s real-time response helps maintain privacy and autonomy.

The integration with screen readers ensures that even users with no vision can navigate the app’s interface using voice commands. The app’s design emphasizes simplicity and speed, minimizing the number of steps required to complete a recognition task.
