Every few steps the system snaps a photo and converts it into sound, giving the users their bearings as they traverse tables and trashcans. (2) No significant between- or within-group effects were observed for cognitive training when a stringent α, corrected for multiple comparisons, was used. By attaching a head-mounted camera to a computer and headphones, the blind users were even able to navigate around a room by the sound cues alone. (1) Very high adherence rates (94%) of the sample and 100% of the cognitive training group indicate that when given adequate individual support, adults with ID/DD can successfully use a cognitive stimulation program. To investigate whether participants with ID/DD would improve in cognitive function after cognitive training, a cognitive training group (N = 11) was compared to 2 control groups, a computer games group (N = 11) and a waitlist group (N = 10) on performance on 15 cognitive functions. However, individuals with intellectual and developmental disabilities (ID/DD) are not provided with opportunities to prevent cognitive decline. There already are devices capable of reproducing Braille characters in real time, but they are based on moving parts that go up and down to form points of symbols. Although there are solutions that can convert text into speech, Braille remains the closest thing to reading for blind persons. There is a growing focus in the United States on preserving cognitive functioning. A touchscreen capable of creating figures and Braille. Typing with the touch typing method significantly improves your computer productivity it increases data.
