- Real-Time Hand Control for Interactive Presentation (2026) · doi
Testing involved only 20 hand movements from a balanced set of male and female subjects with 60 images per gesture; cross-subject validation and cross-dataset evaluation (e.g., testing on external datasets) are absent, limiting generalization assessment for the hand gesture recognition system.

User-centric testing and iteration is mentioned as part of the development strategy, but the paper does not specify the sample size, demographic diversity, gesture learning curve, or adaptation time required for diverse users to achieve proficiency with the gesture control mappings.
Keywords: usability testing user diversity gesture control intuitiveness learning curve user adaptation - Smart Gloves for Sign Language to Text Conversion Translation Using Arduino Mega With 8 Flex Sensors (2026) · doi
The paper demonstrates gesture recognition using threshold-based algorithms with 8 flex sensors on a single gesture set, but does not specify the dataset size, number of unique gestures tested, or validation across multiple subjects. A quantitative evaluation with defined gesture vocabularies (e.g., ASL alphabet, common phrases) and cross-subject validation is needed to establish generalizability.
