At the University of Bristol, researchers have used ultrasound to detect hand gestures. While there are many consumer applications of the technology, such as playing video games and controlling devices around the house, this new “physiologic” way may end up being used by surgeons to browse hands-free through radiological images during procedures.
This can help to maintain sterility while avoiding having to have another clinician control the imaging device’s interface. The same approach may also lead to a time when in-clinic touchscreens, which currently help to spread infections, may no longer be necessary. We can also envision this technology being used for rehab of patients who recover from stroke or musculoskeletal disease.
The researchers used a conventional ultrasound probe to image the muscles of the forearm while different gestures were performed.
