Swiss startup Padrone has created a wearable AI mouse ring that fits the index finger and can turn any surface into a laptop or computer touchpad. The smart ring, dubbed Primera, is currently the subject of a Kickstarter campaign.
The device is worn on the index finger of the user's dominant hand. Among other electronics, it incorporates a six-axis motion sensor, a forward-facing camera, a microprocessor, a Bluetooth LE module, and a rechargeable battery.
The cursor movements on the screen exactly repeat the finger movements, and touching the surface works like a mouse click. It is important to note that all information processing is performed inside the device, ensuring the security of user data.
According to the designers, it has taken the technology team ten years in total to develop the wearable AI mouse ring. In 2024, they’re confident enough to say that they can start releasing the product in May 2025. When the clients receive the ring, they slide it onto their index finger and connect the device to their laptop or computer through a Bluetooth connection, reports NewAtlas.
To activate the Primera, double-tap the thumb on the side of the index finger. The onscreen pointer is then moved appropriately by dragging the fingertip across the desk's surface. A left click is made by tapping the desk with the index finger, while a right click is made by tapping the middle finger.

The index and middle fingers are slid together to scroll. Users can drag and drop objects by pressing the thumb against the side of the index finger. Additionally, the Primera detects the keyboard when the hand is moved to the keyboard to begin typing and immediately enters standby mode until the hand is brought back to the desk.
It is worth noting that the wearable device only works on reasonably well-lit surfaces that don't have overly chaotic color patterns. Battery life also isn't great, as one 100-minute USB charge is said to be sufficient for one full work day.
Padrone says the device should work with any tablet or computer that accepts a Bluetooth mouse, without any added software.
When the company starts production, you can get one for a pledge of €259 (about US$279).
