Smart ring maker Oura has acquired Doublepoint, a company that specializes in gesture recognition for wearables. The Finnish startup uses smartwatches and wristbands as examples of products that benefit from its technology, but Oura will clearly be looking to incorporate it into its rings, in theory allowing you to control your connected devices with hand movements.

Oura said in a press release that the deal sees it inherit an “exceptional team of AI architects and builders from Doublepoint,” including Doublepoint’s four founders. The newly-acquired company will remain in its native Helsinki, where it will work with Oura’s international teams.

It added that Doublepoint’s expertise in helping devices register subtle hand movements will be key, as nobody wearing a smart ring is going to engage with gesture control if they have to thrash their hand around like a conductor.

Oura says it believes that the next generation of wearable AI-powered tech will use a combination of gesture and voice control, and Doublepoint’s background in biometric integration with devices will give it an edge in a competitive market.

Oura’s most recent release is the Oura Ring 4, which Engadget’s Daniel Cooper called “the smart ring to beat” in his long-term review last year. He praised the design, improved data collection and app interface, but was disappointed that even using basic hardware features requires a paid subscription.
