US Researchers have developed a system Called BrainGate2 in which people with neurological disease or loss of a limb can communicate with an unmodified computer tablet. The system uses an array of microelectrodes implanted into the brain. It will decode neural signals associated with the intention to move or operate a limb in real time.

People with Neurological diseases can now perform tasks like text messaging, streaming music or playing videos. The findings could have a major impact on millions of people who have suffered from neurological diseases, limb loss or injury.

A common digital task like sending an Email or browsing the internet can be possible by this system.
One of the participants who has used this system ordered groceries online and played a digital piano. The system even allowed two of its participants to communicate through chat with each other in real time.

Few gestures cannot be accessible like Click and drag or multitouch. Some of these limitations might be overcome by enabling accessibility features by commonly found in the Android OS or any third party programs.
