Park Jungsik and Kim Jong Deok have designed a learning tool, Smart Pillow, which offers an interactive and enjoyable learning experience for children. Contrary to traditional educational toys, the Smart Pillow features a flexible touchscreen LCD display and a diverse offering of software.

Smart Pillow is made from eco-friendly and recycled materials. Its vegetable-based plastic body is covered by a removable and washable cotton layer, so it's completely kid-friendly. The Smart Pillow is intended to help develop children's senses of sight, touch and hearing.
