Seamless User Interface Design

Differences in finger lengths, diameters, dexterity, reach and tactile sensitivity directly impact a user's ability to control and operate haptic interfaces. Handheld device design that does not consider these variations inevitably results in unacceptable levels of input errors, accidental drops damaging the equipment and adding frustration and confusion to the user experience. Unlike any other industry, this lack of usability has spawned a billion-dollar category of protective mobile phone cases that bring back grip features as well as ballistic packaging that protect from drops because the original phone form is not hand friendly. Two excellent icon design examples include the common battery charge level and wireless network indicators found on mobile devices daily.
