Interact With AR Using A Simple Elegant Ring

Interact With AR Using A Simple Elegant Ring

With the introduction of augmented reality a person normally relies on their smartphones or using a handheld device to interact with the virtual images they see using their headset or phone. This makes using this technology in everyday life obvious and most of these devices, other than the smartphone, were not made to go with someone out to the real world. Nat Martin, a graduate from Royal College of Art, wanted to change this by creating Scroll, a ring that fits around a person’s to allow them to interact with virtual images as if the images were right in front of them. For the working prototype Martin created, he assumes the wearer would wear his device on their right forefinger.


The Scroll fits around a person’s ring as if it were an ordinary ring, save for the small elongated side of it. The ring contains a gyroscope to detect the direction the wearer moves their hand to have the virtual images act accordingly. This allows the wearer to freely move their hand to interact with the digital objects they observe through their headset. Unlike traditional augmented reality devices, the user does not have to have the hand tracking unit within sight of the headset. Instead, the user could freely keep their hand by their side and continue to use their Scroll. This eliminates the need for a user to interact with their device through an exaggerated gestures.

The gyroscope allows for Scroll to reacts to a wearer’s basic gestures of their hand, shifting from side to side, and using the finger it sits on as a laser pointer. The ring was also installed with a scroller, granting the wearer the ability to run through their activities similar to the third button found on a mouse.


When augmented reality headsets rely less on entirely covering the user’s head, this type of remote could prove useful in everyday life. During a conversation, the person using the device could see a quick reminder of an event happening in twenty minutes and quietly dismissing it with a wave of their hand rather than removing their phone to silence the notification or disrupt the conversation. It could also prove useful during business hours for people who get too involved with their work and need the visual image of a notification to break away.


Scroll syncs with existing augmented reality headsets, such as Google Cardboard, ARKit by Apple, and Microsoft’s HoloLens. Martin created Scroll for the purpose of developers to rethink how preexisting augmented reality devices work, and how the devices should get brought into a person’s everyday life.
