Another report suggests the new iPhones will have a touch-based home button
An iPhone without the signature circular home button? Yes is
sounds strange and outlandish, but it might just turn out to be true. This is
now the second time we have heard of such a possibility from industry
sources, making it sound at least a bit more plausible.
The concept is pretty self-explanatory - replace the physical home
button with a touch-sensitive surface, which will essentially house Apple's
fingerprint scanner with some added tap and press detection functionality. We
have seen it done before by other manufacturers, so it is definitely plausible.
However, things do get a bit more complicated if Cupertino doesn't wish to
completely loose the feedback sensation of pressing a button.
Of course, one possible solution would be to implement haptic
feedback similar to that in recent MacBooks or the 3D touch on the iPhone
itself. A subtle vibration done properly can go a long way in creating a
convincing illusion of touch.
There are plenty of potential benefits of such a move away from
the home button. For one, the step fits nicely into Apple's ongoing push to
flatten out the surfaces of its smartphones, the missing 3.5mm audio jack being
another example as well. Also, both of these omissions should play well with
the alleged waterproofing the iPhone 7 will offer. Last, but not
least, there is also the issue of reliability. It is no secret that physical
buttons are a weak point in any device and a flat touch surface would likely be
more durable.
