Abstract :
Contact force profiles deployed at the finger tip in the context of tactile letter recognition were compared in young and older adults. Older adults showed lower normal force and increased letter-to-letter variability in normal force as compared to young adults. This likely contributed to longer contact times and lower performance accuracy in older adults, suggesting a central contribution to the decline with age in tactile letter recognition.
