Mark Gurman, on 9to5Mac:
According to sources, the iOS version of Force Touch is known internally as “Orb.” Instead of opening up a large window of extra controls that did not fit on the screen, as is done on the Apple Watch, Force Touch on the iPhone is designed to skip existing lists of options or button presses. “There is consistent usage of Force Touch across the operating system to ‘shortcut’ actions,” rather than present new options like with the Apple Watch, according to a source.
I've tried Force Touch on both the Watch on the Mac, with the former seeming like a more obvious place for it than the latter. I dig the Force Touch trackpad from a technical standpoint, but the usability is hit and miss. For me, it's use is mainly relegated to looking up dictionary definitions as I write, but that's not even available in Chrome (my mistake for using Chrome in the first place). Other available uses just don't come to mind in the moment as I've become accustomed to a certain workflow.
This technology on an iPhone has some interesting possibilities. I really like the idea of being able to press on an app icon and get a shortcut menu to certain functions within that app right from the home screen. Thinking about where Force Touch makes the most sense, the phone seems obvious, unlike the Mac. Glad that the months of rumor smoke seem to be paying off with reality fire. Though, we won't know for sure until the September 9th event, if the rumor smoke signals are guiding us in the right direction.
