With the objective of designing an accessible date picker, we heuristically evaluated features of 14 date-picking widgets / calendar for accessibility by visually impaired users. We found accessibility problems with most products. We did a comparative evaluation of various parts of products to understand the relative accessibility of the default views, the month selection interfaces and a far-away date selection interfaces with 12 blind users. We found that a brief introduction of about two minutes was enough for users to be able to successfully perform all tasks. With the exception of month selection interfaces, the differences in time taken and user rating was not significant. We also learnt about several design issues that were relevant to the design of date pickers. All these issues will help us to build an accessible date picker that can be used by many applications on smartphone.
