The user is immediately presented with a series of options to populate a search in order to find the product they need. Each field is customized to make entry on mobile handsets as easy as possible. Here, the size is a custom UIpicker, with sizes only in the offered ranges. Another example (not shown) is the part number lookup, which offers auto-suggestion.
The entire process is also error-free. The user is not just assisted with entry but restricted from entering inappropriate values by the use of pick lists, and so on. As one visible example, the Search button is grayed out, since the user has not entered enough information yet.
