Feature: Medical
medical imagery through a combination of gesture and voice control, minimising the amount of contact they need to have with equipment or patients while reducing their reliance on potentially imprecise verbal communication with assistants during an operation. Surgeons have always been required to
maintain high levels of sterility, but it was during the COVID-19 pandemic, with its heightened infection risks, that this type of HMI really came into its own. With surgeons now highly reliant on 3D images to carry out complex procedures, any technology that offers them added control with minimum disruption is a welcome advance. Tis kind of innovation, made possible through the development work of organisations like Microsoſt Research and Grayhill, marks a new era in seamless and hygienic interaction with technology, providing innovative solutions to a variety of challenges. So where will the next wave of HMI innovation take us? Developments in AI
may soon deliver HMIs that allow machines to act intelligently and communicate proactively with humans. Te next era of human-machine interaction will demand interactive, smart applications powered by processors that have HMI capabilities built in.
Early indications of the potential of
this next HMI generation are already with us, for example in the form of smart buildings which allow entry based on facial recognition. With AI that can operate at the network edge, in any number of remote locations, we will see touchless machines that allow authorised personnel to operate them through gesture. It is easy to imagine many healthcare applications for such technology, both in hospitals and the home. A marriage between HMI and AI could facilitate remote consultations and frictionless diagnostics, saving the need for vulnerable patients to travel to a doctor. Adding greater intelligence to HMI
devices will furthermore allow for accurate
analytics and predictive maintenance. Complex medical equipment will automatically draw human attention to a potential fault that needs fixing. It may even be able to repair itself and report the fix to hospital management. Smart sensors and real-time monitoring
systems are also an effective way to reduce waste, ensuring for example that cooling chains for medications are better managed and exposure to harmful contamination minimised. Smart HMI-driven solutions like this are not only more effective than the more primitive solutions they replace, they also generally use less energy and involve fewer processes, helping to decrease medicine’s not inconsiderable environmental impact. In the rapidly advancing field of healthcare
technology, HMIs are fast becoming an indispensable feature of medical devices. As they become more intuitive and immersive, the convergence of HMIs of other advanced technologies will further transform the medical industry as well as patient health.
OCTOBER 23, 2025 THE GRAND CONNAUGHT ROOMS, LONDON ENTRIES NOW OPEN!
The IEA and EIA Awards are joining forces to present the Instrumentation & Electronics Awards. This prestigious event will recognise and celebrate innovation and excellence across both industries.
