Researchers at North Carolina State University have developed technology that turns a smartwatch user's forearm into a trackpad, allowing the user to scroll, zoom, click on icons and so on. The system relies on a radar system that tracks the movement of a user's fingers on the forearm and monitors pressure on the skin of the forearm, providing the same level of force-touch detail available on laptop trackpads.

"Smartwatch screens are too small for the touch interactions people use every day on phones and laptops, such as two-finger scrolling, pinch-to-zoom or pressing harder to trigger a different command," says Chenhan Xu, corresponding author of a paper on the work and an assistant professor of computer science at NC State. "Our goal was to develop a small, wearable technology that would provide that level of interactive control for users."

EpiPad uses wrist-mounted radar to turn the forearm into a trackpad, letting smartwatch users scroll, zoom and click.

EpiPad uses a 5 × 4 mm millimeter-wave radar array to detect finger movements and pressure on the forearm.

The researchers estimate its functional components could cost less than $10, potentially enabling integration into future wearables.

Lithuania Receives its Forst Thales GM200 MM/C Multifunction Radar

Lithuania has reinforced its air surveillance and counter-battery capabilities with the first delivery of a Thales GM200 MM/C radar system. The radar arrived in late October 2026 under a 2024 purchase agreement with the Netherlands. The GM200 MM/C is a 4D AESA multi-function ground radar that simultaneously detects artillery and rocket fire and tracks aircraft and drones. Lithuania’s defence minister says the system will significantly improve the army’s ability to locate artillery.

Under a government-to-government deal signed in January 2024, Lithuania’s Defence Material Agency is acquiring multiple GM200 MM/C units from Thales Nederland via the Dutch COMMIT procurement agency. The contract is valued at around €126.7 million and includes logistics, training and spares. The purchase opens the door to closer collaboration with NATO allies, as the DMA director noted, highlighting the opportunity for joint acquisition and support.
