Abstract Haptic displays are crucial for facilitating an immersive experience within virtual reality. However, when displaying continuous movements of contact, such as stroking and exploration, pixel-based haptic devices suffer from losing information between pixels, leading to discontinuity. The trade-off the travel distance elements their pixel size in thin wearable hinders solutions that solely rely on increasing density. Here we introduce a continuity reinforcement skeleton, which employs physically driven interpolation enhance information. This design enables off-plane displacement move conformally display gaps. Efforts made quantify quality using geometric, mechanical, psychological criteria. development integration one-dimensional, two-dimensional, curved with reality systems highlight impact skeleton display, showcasing its potential improving experience.
