This egg-shaped controller wants to replace your mouse
UK startup NextAxis Design has launched a Kickstarter campaign for OVO, a palm-sized egg-shaped controller that replaces traditional mouse movement with tilt, rotation, and gesture recognition. The device weighs just 98 g and measures 48×61 mm — roughly the size of a real egg. For anyone who spends long hours at a desk and has noticed wrist discomfort, it's at least worth knowing it exists.
The concept
OVO ditches the flat-surface tracking that every mouse has used for decades. You control the cursor by tilting and rotating the egg in your hand, and it works equally well resting on a desk or held in the air as an "air mouse." The shell is split into two zones: the upper half handles cursor movement and clicks, while the lower half is reserved for swipes and scrolling — both using a capacitive multitouch surface.
Inside sits an ESP32-S3 microcontroller alongside a three-axis accelerometer and magnetometer.

The claim
NextAxis says OVO's balance-based control system — which is patent-pending — puts the hand in a more natural position and reduces wrist strain during long computing sessions. Those claims have not been independently validated by any ergonomic or medical body, so treat them with appropriate caution. The ergonomic mouse market already has well-established alternatives: Logitech's MX Vertical and M575S trackball both have years of real-world user data behind them and are widely available in the US and UK.
NextAxis positions OVO primarily for designers, video editors, and 3D artists who need precise spatial input — and also flags it as a TV remote replacement. A $250,000 stretch goal on Kickstarter would unlock an open API for the Arduino ecosystem, broadening its appeal to developers and hobbyists.

Price and availability
The early bird Kickstarter tier is priced at $109, rising to a planned retail price of $199, according to New Atlas. Shipping is projected for December 2026. No UK-specific pricing or regional pre-order platform has been announced. As with any crowdfunding campaign, delivery timelines and final product specs can change — back with that in mind.
