Parents with small kids have a new tool to help teach sensory processing skills. Hopster, an educational app for the under-six crowd, has released Sense, a new multi-sensory digital playroom. Built to introduce children to fine motor skills and spatial reasoning, the playroom consists of nine screens that include textures, sights and sounds. Additionally, it has undergone specialized testing to ensure that it meets the needs of kids with autism. Included in the same low monthly fee that Hopster charges for all its programming, music and games, Sense might be the feature that makes Hopster a must-have learning opportunity.
