This Oware-inspired gaming controller replaces joysticks with a precision half-ball control system - Yanko Design

"Control PlusArc is built around the idea that interaction should feel natural rather than mechanical. Instead of relying on standard analog sticks, the design introduces a semi-spherical control mechanism that encourages controlled, intentional movement. The controller's overall oval form factor reflects this philosophy as well."

"The concept controller is inspired by Oware, known for its rhythmic and thoughtful movement of pieces across carved pits on a wooden board. Instead of mimicking the visual style of the game, the Control PlusArc borrows its philosophy of deliberate interaction. The controller's oval shape emphasizes the organic contours of an Oware board, creating a tactile connection between hand movement and the act of play."

"Unlike a full trackball or freely spinning joystick, the half-ball structure introduces clear boundaries to movement. Players can roll the control surface in different directions, but the restricted geometry ensures that movement remains precise and predictable. This design choice prevents the kind of uncontrolled spinning that often accompanies traditional trackballs, instead reinforcing a sense of intentional navigation."

Control PlusArc is a concept controller designed by Kusi Boateng Arthur that challenges conventional gaming peripheral design by introducing a semi-spherical control mechanism instead of standard analog sticks. The controller features an oval form factor that encourages comfortable, fluid hand placement and continuous grip stability. Inspired by Oware, an African board game emphasizing deliberate piece movement, the design borrows this philosophy of thoughtful interaction. The half-ball control structure provides clear movement boundaries, enabling precise and predictable navigation while preventing uncontrolled spinning associated with traditional trackballs. This approach reflects a broader industry trend toward rethinking the relationship between hand and controller through more tactile, natural interaction methods.
