I am on the 3rd chapter of Joshua Clark's Tapworthy : Designing great iPhone apps
And I was really taken aback by the first few pages. In these first few pages Joshua Discusses the "thumb hotspot" i.e area of the iPhone screen over which the thumb can wander without being stretched or squashed.
He also shows some examples like this ToDo list app :
The standard iPhone toolbar and tab bar always go at the bottom edge of the iPhone screen in convenient thumb-tapping range. ToDo list app Things puts the Edit button at top right safely out of accidental tap range .
New app interfaces clearly deviate from this . For example apps like Vine and Google+ and others Place navigation controls at the top left corner
which clearly is not in the "thumb tapping" zone. Is this a good or a bad thing ?
On a similar note , considering Google Drive's iPhone app
IMO adding (+) a file is a more frequent and important function than refreshing . Still the app has (+) button away at the top right corner (out of the thumb zone) and refresh button at the bottom left (inside the thumb zone) which clearly contradicts with the ToDo list app example.
To be honest I find tapping the (+) button at the top right easier than bottom left refresh button. So, What's up?
I can't question the credibility of the book, since it's a bestseller and Joshua Clark is a really talented and well known interaction designer.This book was published in 2010, have practices changed in three short years ? I hope not. It'd be great if someone can pull me out of this mess. Thanks
