I've been reading some articles about user behavior on mobile devices, and a lot of them keep showing this image:
When trying to figure it out the best menu on the app I'm working on I noticed the bottom center area is the easiest for the user to reach. With this in mind and with the new Google Material design FAB button, it came to my mind to have a central FAB trigger to open up the main menu of the app.
- Top bar: Far away for most users.
- Side bar: No space for it.
- Google Material Drawer: Still need to reach the top to open it.
So my idea is to have a central FAB trigger, like this image:
When the user clicks, it animates to fill the screen with the menu.
The only consideration I would have, is when creating an app that needs a search function, or an e-commerce, for example, when we need to keep user updated with how much items he has in the shopping cart.
Using both, top bar (for search & cart) and central FAB (for main menu), would be acceptable?
With these points, what do you guys think? Is this a good idea? Or should i stay with the old, traditional top bar menu?
What other alternative should I consider when chosing the menu to my app?
