Thumb does matter
A special study conducted at the University of Multimedia (Malaysia) showed that the thumb size of each specific user directly affects the user’s satisfaction with the product, if such a product is a mobile phone. The main thing that attention was drawn to in the study is the function of dialing SMS. In addition to size, the researchers measured the effect on the satisfaction of such factors as the size, shape and texture of the buttons, the distance between them, the design of the buttons and their simplicity.

Anatoly Kostin: How is usability measured? Not exactly in parrots
Usability metrics are currently contained in ISO 9126-4 and ISO 9241-11. However, they are blurred in content, incomplete, often do not coincide with each other, and sometimes contradictory. All this makes it difficult to work with them and reduces the effectiveness of usability testing. Anatoly Kostin, a staff member of the Institute of Psychology of the Russian Academy of Sciences and the scientific director of USABILITYLAB, conducts a comparative analysis of these standards and offers his own version of metrics.
