# Half-Ball Game Controllers Control PlusArc Replaces Joysticks with a Half-Ball Input System By Amy Duong | Published 2026-03-18 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/control-plusarc References: [behance.net](https://www.behance.net/gallery/240701697/Control-PlusArc)  The Control PlusArc controller is a concept [gaming device](https://www.trendhunter.com/trends/mk1-controller) designed by Kusi Boateng Arthur that replaces traditional [analog sticks](https://www.trendhunter.com/trends/steam-controller-1) with a semi-spherical control interface. The design draws from the mechanics of the [board game](https://www.trendhunter.com/trends/boardrop) Oware, translating its controlled hand movements into a digital input system. Users roll the half-ball surface to direct movement across the game environment. The controller is shaped with an oval body that supports a continuous grip and positions the control system at the center. The controller integrates a semi-spherical input surface embedded within the main body, limiting rotation while allowing directional control. The housing follows a smooth oval geometry that fits within the palms. The half-ball component is fixed within a recessed cavity to prevent full rotation. Buttons are arranged around the central input area.
