Camera Phone

A camera phone is a mobile phone equipped with a built-in image sensor, which in an accessibility context serves as the input device for a wide class of vision-based assistive applications. Modern smartphone cameras enable live scene description (Seeing AI, Be My AI), object recognition, optical character recognition, currency identification, barcode scanning, colour identification, and camera-based wayfinding systems that detect fiducial markers or environmental features. Because the device is a mainstream consumer product rather than a dedicated accessibility appliance, camera-phone-based assistance avoids much of the social stigma associated with specialised hardware, and benefits from continuous hardware improvements that blind users would otherwise have to pay a disability-tech premium to access.
