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 youre looking at the board or navigating the game entirely through touch.Designers: Ana K. & Sandro Lominashvili (Integrated Architecture)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 youre looking at it or feeling it.Of course, the board extends this geometric thinking beyond the pieces themselves. Rather than standard flat squares, the playing surface alternates between convex and concave areas that mirror the piece design. This creates a sculptural quality that transforms the entire chess set into a cohesive design statement while providing clear tactile boundaries for navigation during play.The tactile experience becomes especially meaningful when you consider players with visual impairments. The geometric differences make it possible to distinguish between sides instantly through touch alone, while the undulating board surface provides clear orientation cues. You can run your fingers across the pieces and board, understanding the game state without relying on sight, making chess truly accessible to everyone.That said, the visual impact remains striking for sighted players. The interplay between the smooth and textured surfaces creates dynamic shadows and visual interest that elevate chess from a simple board game to a sculptural art piece. The monochromatic color scheme lets the geometry take center stage, emphasizing form over decoration.The choice of 3D-printed PLA reflects modern manufacturing sensibilities while keeping the concept environmentally conscious. At 455 455 100 mm, the set maintains a substantial presence without overwhelming the space, making it suitable for both serious play and display. The material choice also ensures consistent tactile feedback across all pieces, which becomes crucial for the accessibility features to work effectively.Youll notice how every design decision serves multiple purposes, from the pure aesthetic appeal to the practical accessibility benefits. This kind of thoughtful integration shows how good design can enhance experiences for everyone without compromising on visual appeal or functionality.The +- Chess set represents what happens when designers approach familiar objects with fresh eyes and inclusive thinking. It proves that accessibility and beauty arent competing goals; theyre complementary aspects of truly thoughtful design that make experiences better for everyone involved.The post +- Chess Set Concept: Modern Geometry and Accessibility Meet on the Board first appeared on Yanko Design.
