Wearable Ring-Sized Smart Touchpad Design -- 2

I’d like to turn an idea I have into a working wearable: a ring-sized smart touchpad that behaves like a computer mouse. Picture a sleek band you slide onto your finger—tap or swipe on its tiny surface to left-click, right-click, or scroll just as you would on a trackpad.

Scope
• Design the electronics and enclosure for a ring-form factor.
• Implement reliable click and scroll detection on the ring’s touch surface.
• Deliver a functioning prototype that pairs over common wireless standards (Bluetooth LE preferred, open to suggestions) and is recognized by a Windows or macOS computer as a standard HID mouse.
• Provide firmware, schematic, 3D-printable enclosure files, and clear build/programming instructions so I can reproduce or iterate on the design.

Key requirements
• Wearable size and weight—comfortable for everyday use.
• Intuitive “tap for click, slide for scroll” gesture mapping.
• Battery life suitable for a full workday with USB-C or magnetic charging.
• Latency low enough to feel as responsive as a regular mouse.

I’m flexible on the specific microcontroller, touch sensor, or antenna solution so long as the final unit meets the usability goals above. If you’ve built similar HID wearables, please highlight them and outline the approach you’d take from concept through prototype hand-off.
