Identifying the relevant individual attributes for a successful non-visual mobile experience

Motivation -- To understand the individual differences with the greatest impact on a blind user's mobile interaction effectiveness and learning abilities. Research approach -- We performed a semi-structured interview to 10 specialized professionals (psychologists, occupational therapists, rehabilitation technicians, IT teacher) working closely with blind users. Findings/Design -- Results suggest that peripheral sensitivity, spatial ability, blindness onset age, age, intelligence and memory are the characteristics affecting user capabilities the most. Research limitations/Implications -- This study offers a wide view on the possible influencing attributes. Empirical studies are required to dissect the impact of each characteristic in mobile blind users' performance. Originality/Value -- We contribute with an understanding of the individual differences among the blind population that may affect mobile interaction. Take away message -- Individual differences among the blind have greater impact than those between sighted users. Understanding these differences is mandatory.
