Sensory Tree: a Tangible user interface for enhancing children’s sensory integration through tactile intervention

The “Sensory Tree” system is an innovative Tangible User Interface (TUI) designed to help children improve sensory integration disorders through tactile interventions. By combining tactile, visual, auditory, and proprioceptive stimuli, it enhances multi-sensory coordination abilities. Unlike traditional sensory training, which often lacks interactivity, the Sensory Tree merges physical objects with virtual environments for a more engaging experience. This system captures children’s interest through diverse sensory experiences, using touch, vision, hearing, and motor coordination. Tactile stimulation involves different textures, visual stimulation utilizes color and shape changes, auditory stimulation enhances experiences with music and sounds, and proprioceptive input is provided through activities and games. This comprehensive design improves children’s sensory processing and adaptation to daily sensory information. The study evaluated 16 children with sensory integration issues using a mixed-methods approach, gathering both quantitative and qualitative data. Effectiveness was measured through task completion, task time, and error rates, alongside interviews with parents and therapists regarding children’s engagement. Results indicated significant improvements in sensory processing abilities and social interactions, with positive feedback on the system’s design and effectiveness, highlighting its value as a supplement to traditional therapies.
