We have a mobile app, which on the same screen, has a means to select Time and a means to select Duration; like this:
Time Left Home is a time of day
Planned Work Duration is duration
Both of these options open the standard dialog for selecting a time as such:
There has been some confusion found in our user testing about whether the user thinks Planned Work Duration should be how long they are working for, or to what time they are working till.
What is the best way of comunicating this differentation to the user? Has there been any studies on how to do this? Should we consider icon use - if so what icon best represents duration in your experience? Essentially, how can we make it clear that we need Duration rather than Time.
The requirements are:
- The fields must remain in the same order
- The fields must use the standard time selector (so we are limited as to what we can change there)
We have tried playing around with the terminology but that also seems somewhat problematic and subjective.
