PURPOSE: In our modern society, many touch screen applications require hand-eye coordination to associate an icon with its specific contextual unit on phones, on computers, or in public transport. We assessed the ability of @entity1 with @entity1020 ( @entity1020 ) to explore scenes and to associate a target (animal or object) with a unique congruent scene (e.g., to match a fish with the sea) presented between three other distractors on a touch screen computer. METHODS: Twenty-four @entity1 with @entity1020 (64 to 90 years) with best-corrected visual acuity between 20/40 and 20/400 as well as 17 age-matched (60 to 94 years) and 15 young (22 to 34 years) @entity1 with normal visual acuity had to match a target with a congruent scene by moving their index finger on a 22-in touch screen. RESULTS: @entity1 were as accurate (98.7% correct responses) as the age-matched control (98.9% correct responses) and young @entity1 (99.3% correct responses) at performing the task. The duration of exploration was significantly longer for the @entity1020 @entity1 (mean, 4.13 seconds) compared with the age-matched group (mean, 2.96 seconds). The young @entity1 were also significantly faster than the old group (mean, 0.93 seconds). The movement parameters of the older @entity1 ( @entity1 and old control subjects) were affected compared with the young; the peak speed decreased (-8 cm/s) and the movement duration increased (+0.9 seconds) with age compared with the young group. CONCLUSIONS: @entity1 with @entity1020 are able to perform a contextual association task on a touch screen with high accuracy. The @entity1020 @entity1 were specifically affected in the "exploration" phase; their accuracy and movement parameters did not differ from the old control group. Our study suggests that the decline associated with @entity1020 is more focused on the duration of exploration than on movement parameters in touch screen use.
