+- Chess Set Concept: Modern Geometry and Accessibility Meet on the Board - Yanko Design
"Chess sets have traditionally relied on color and intricate figurative details to help players distinguish between sides, but this approach often creates barriers for people with visual impairments or those playing in low-light conditions. Most designers focus on making chess pieces more ornate or visually striking, yet few consider how the fundamental interaction with the game could be improved through thoughtful geometric design."
"What makes the +- Chess set particularly compelling is how it tackles these accessibility challenges through pure geometric logic rather than decorative solutions. By using convex shapes for one side and concave shapes for the other, this concept design creates instant visual and tactile distinction that works equally well whether you're looking at the board or navigating the game entirely through touch."
"The pieces themselves follow a strict geometric vocabulary that feels both minimalist and purposeful. You get smooth, domed surfaces for the "+" side and scalloped, indented profiles for the "-" side. Each piece type remains distinguishable through height and form, but the real innovation lies in how the surface geometry immediately tells you which side each piece belongs to, whether you're looking at it or feeling it."
The set uses convex forms for one side and concave forms for the other to create immediate visual and tactile differentiation. Pieces follow a strict geometric vocabulary with smooth, domed surfaces for the "+" side and scalloped, indented profiles for the "-" side. Piece types remain distinguishable through variations in height and form while surface geometry signals side membership by sight or touch. The board alternates convex and concave squares that mirror piece geometry, creating sculptural continuity and clear tactile boundaries for navigation. The approach prioritizes accessibility for visually impaired players and improves use in low-light conditions.
