A hand-wearable device outfitted with data interface electronics is provided. The device is secured to its user by means of a comfortable material integrated across the top of the hand. The device includes a central palm section containing complex three-dimensional geometry and modular features for adjustable structures to house switch sensors. These structures account for each fingertip's location and orientation relative to the rest of the user's hand. Features to accommodate the comfortable securing material are built into the device to ensure the device does not shift or move around relative to the user's hand while being worn and operated. Integrated switch sensor and various power and transistor-based electronics allow the device to function and communicate with other computers and like devices. The device is worn on the left, right, or both hands simultaneously to enable access to the maximum number of potential sensor commands for a user.
