We present OldGen, a prototype framework where a novel
concept enables accessibility features on generic mobile
devices, by decoupling the software user interface from the
phone’s physical form factor. This opens up for better customization
of the user interface, its functionality and behavior,
and makes it possible to adapt it to the specific needs of
each individual. OldGen makes the user interface portable,
such that it could be moved between different phone hardware,
regardless of model and brand. Preliminary observations
and evaluations with elderly users indicate that this
concept could address individual user interface related accessibility
issues on general-purpose devices.
