Haptic holograms

The holograms we’ve all seen in person or in the movies tend to be 2D or 3D projections of light that show objects or people hovering in the air. What these projections all have in common is that if you reached out to grab them, you would only get a handful of air. That won’t be the case by the mid-2020s. New technologies (see examples: one and two) are being developed to create holograms you can touch (or at least mimic the sensation of touch, i.e. haptics). Depending on the technique used, be it ultrasonic waves or plasma projection, haptic holograms will open up an entirely new industry of digital products that we can use in the real world.

Think about it, instead of a physical keyboard, you can have a holographic one that can give you the physical sensation of typing, wherever you’re standing in a room. This technology is what will mainstream the Minority Report open-air interface and possibly end the age of the traditional desktop.

Imagine this: Instead of carrying around a bulky laptop, you could one day carry a small square wafer (maybe the size of a thin external hard drive) that would project a touchable display screen and keyboard hologram. Taken one step further, imagine an office with only a desk and a chair, then with a simple voice command, an entire office projects itself around you—a holographic workstation, wall decorations, plants, etc. Shopping for furniture or decoration in the future may involve a visit to the app store along with a visit to Ikea.
