ABSTRACT
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.

Blind people and mobile keypads: accounting for individual differences
INTERACT'11: Proceedings of the 13th IFIP TC 13 international conference on Human-computer interaction - Volume Part INo two persons are alike. We usually ignore this diversity as we have the capability to adapt and, without noticing, become experts in interfaces that were probably misadjusted to begin with. This adaptation is not always at the user's reach. One ...
Assessing mobile-wise individual differences in the blind
MobileHCI '10: Proceedings of the 12th international conference on Human computer interaction with mobile devices and servicesEvery human is different. This diversity has not been given enough attention in mobile UI design. Disabled groups, with specific individual differences, face difficulties with traditional or stereotypical interfaces. My goal is to identify the ...

ASSETS '11: The proceedings of the 13th international ACM SIGACCESS conference on Computers and accessibilityThe emergence of touch-based mobile devices brought fresh and exciting possibilities. These came at the cost of a considerable number of novel challenges. They are particularly apparent with the blind population, as these devices lack tactile cues and ...
