Key points
- Three participants with tetraplegia used an iBCI with implanted motor cortex arrays.
- Neural activity was decoded in real-time to control an unmodified commercial tablet as a point-and-click wireless mouse.
- Participants successfully used common applications like web browsing, email, and messaging.
- This marks the first demonstration of high-performance iBCI control over a general-purpose mobile device by individuals with paralysis.

Abstract
General-purpose computers have become ubiquitous and important for everyday life, but they are difficult for people with paralysis to use. Specialized software and personalized input devices can improve access, but often provide only limited functionality. In this study, three research participants with tetraplegia who had multielectrode arrays implanted in motor cortex as part of the BrainGate2 clinical trial used an intracortical brain-computer interface (iBCI) to control an unmodified commercial tablet computer. Neural activity was decoded in real time as a point-and-click wireless Bluetooth mouse, allowing participants to use common and recreational applications (web browsing, email, chatting, playing music on a piano application, sending text messages, etc.). Two of the participants also used the iBCI to "chat" with each other in real time. This study demonstrates, for the first time, high-performance iBCI control of an unmodified, commercially available, general-purpose mobile computing device by people with tetraplegia.
