Futuristic movies and TV shows like Minority Report show characters using cool floating computer screens they access by waving their hands in the air while they have a super serious look on their face.
Even cooler- when the floating computer screen is voice activated, and capable of displaying those really awesome looking 3D maps they spin in the air when they're making plans.
But, like most tech that looks really cool on film, the reality would be an annoyingly unmanageable device that makes you look stupid while you use it and makes everyone nearby hate you! (NSFW language)
