- Obfuscation(also: Content Obfuscation, Visual Obfuscation)
- AI-enabled techniques that automatically detect and remove or conceal private content in images and videos by applying filters such as blurring, masking, or blocking. In the context of visual assistance technologies, obfuscation aims to protect blind users from inadvertently…
- Off-Device Processing(also: Cloud Processing, Remote Processing)
- Computing performed on external servers rather than on the user's local device, requiring data to be transmitted over the internet. In the context of visual assistance technologies, off-device processing raises privacy and security concerns because users' images and videos —…
- On-Device Processing(also: Local Processing, Edge Processing)
- Computing performed directly on a user's device (phone, tablet, or wearable) rather than sending data to external servers. On-device processing is particularly valuable for privacy-sensitive accessibility features because it keeps personal visual data under the user's control,…
- On-device Recognition(also: On-Device Inference, Edge Recognition)
- Performing pattern recognition - such as sign language recognition, speech recognition, or computer vision - locally on the user's device rather than by sending input to a remote server. On-device recognition matters for accessibility because it preserves privacy (camera or…
