The pressure-ignorant touch screen is an anomaly, a transitional technology that must inevitably give way to something better. The pressure-sensitive screen allows devices the physical button's advantage of a more confident handgrip (unencumbered by fear of accidentally triggering a function) and the mouse's advantage of hover effects.

Apple has already taken the step of patenting their own version of a pressure-sensitive screen. In the interest of "skating to where the puck will be", what kind of applications do you envision for this type of technology?

So is there also a tactile feedback in this type of display? –  AndroidHustle Jun 27 '13 at 10:59
    
There is no single answer to this, you're just asking for a load of examples. A better question would be 'is pressure sensitive screen suitable for X type of system, and I'd not why not' because that is a single specific question and not a broad discussion topic. Do you have a situation in mind? –  JonW Jun 27 '13 at 11:19

1) Virtual instruments. The touch-screen piano is a cheesy novelty without touch response. For it to be truly useful, of course, pre-hoc feedback will be necessary, but pressure sensitivity will be one component that advances the touch screen instrument.

2) Hover effects. Previously afforded only to devices with a mouse and cursor, the hover effect is essential to tooltips, link-testing, and a sort of visual substitute for tactility, that is an electronic equivalent of running your fingers over something to probe and test it.

3) Replacing double clicks or push-holds. The double click is mechanically incompatible with a touchscreen. A double-tap on a touchscreen requires a user to physically lift their finger off the screen and re-engage it; it's simply too slow to work. Meanwhile a push-hold where a user holds their finger on a control for slightly longer inevitably feels wrong. Even if the requisite delay is well calibrated, such as on BlackBerry X, it is an intrinsically unsettling feeling. Rather than making it a difference of time, then, pressure-sensitive screens can allow a difference of force. A tap can activate a lighter function and a press can activate something more consequential.

Specific applications include dragging objects, renaming or editing, and popping up context menus.
