The phrase "a cursor or a" is grammatically correct and can be used in written English.
It can be used when discussing options or alternatives related to a cursor, typically in a technical or computing context.
Example: "You can select a tool from the menu, such as a cursor or a pointer, to navigate the interface."
Alternatives: "a pointer or a" or "a marker or a".
Existing implants, about the size of a thumbtack, have allowed a dozen or so patients to control a cursor or a robot arm just by thinking about it.
He has analyzed brain-machine interfaces, which translate brain signals into computer input to move, say, a cursor or a robotic arm.
With the help of algorithms and filters to smooth out anomalous signals, the computer can translate those intentions into instructions that can move a cursor or a wheelchair.
He highlights Air View and Air Gesture (the former produces a cursor or details from a calendar when you hover your finger over the screen; the latter lets you control the screen, say with swiping, without actually touching it).
Researchers have made tremendous strides in developing ways for patients to move a computer cursor or even an artificial arm using electrodes implanted in the brain.
In recent years, scientists have worked to create devices called brain-machine interfaces (BMIs) that can pick up these interrupted electrical signals and control the movements of a computer cursor or a real or virtual prosthetic.
These interfaces typically decode brain signals from the surface of the skull through EEG or implanted electrodes and then translate the signals into a motion command for a robotic prosthetic limb or a cursor on a keyboard.
The field of "brain prosthetics" has been dominated by efforts to restore physical abilities, like devices that use brain activity to move a robotic arm or a cursor across a screen.
Scientists have previously taught monkeys and human subjects to control a cursor on a screen or a simple grasping hand via their brain activity, but this is the first time experimenters have demonstrated that it is possible to perform complex behavioural tasks this way.
Therefore, Comet's pitch is that advertising is far more successful when banners are accompanied by a cursor with a branded image or logo.
They've developed methods to decode signals from electrodes implanted in the brain so that a paralyzed person can control a cursor on a computer screen or manipulate a robotic arm with their thoughts alone.
