Oh I love this!! Firstly, you have to watch the video (I'll add the link in comments) . A dad has invented an app to help his young daughter who has autism communicate with him better it's called TippyTalk
"The TippyTalk app allows a person with a verbal disability to communicate by translating pictures into text messages, which are then sent to a family member or care givers phone or tablet. This allows the person who is non-verbal to communicate and express a desire, want, need or feeling. This communication is not restricted by distance, the person they wish to communicate with can be anywhere in the world. TippyTalk also reinforces language development, by allowing a parent or caregiver record their voice over each picture. TippyTalk grows and evolves as the needs of your loved will also."
