ADHDreamer, hopes to use technology to create a better learning environment for ADHD patients and providing support for them by implementing technology products around the school campus. The page for the ADHD kids is categorized into two parts. The to-do list and the chat room serve to assist the daily lives of the ADHD kids, while the emotion game and the organizing things game is to provide training for ADHD kids to improve their conditions, thus providing them with a healthy mental life. While for the page for the general public, a brief test and information extracted from the HK Association for ADHD are provided to check if the users have ADHD. We have also created a VR video that provides people with a chance to look into a simulated situation on what they might need to encounter. The app, includes 3 parts. For the part for ADHD children, functions such as emotion game, organise things game, to-do list and chatroom help them to learn how to distinguish others' emotions, allow children to learn how to pack their school bags, train them to memorise things well and providing a chance for them to make new friends respectively. The part for general public includes AD/HD tests and information about ADHD are provided, allowing the public to test whether they have ADHD, also allowing them to understand ADHD better For promotion of our app, we have developed a VR video, website and social media accounts and AR lets the general public look into a simulated situation faced by ADHD kids, allowing users to know more about the inspirations of our app and help users efficiently.
