ARC is the first pen specifically designed for people with Parkinson’s living with Micrographia. This condition can result in small, cramped and often uncomfortable handwriting. Many people with this motor control difficulty give up the practice of writing or drawing altogether. Dopa Solution’s aim is to focus on higher level needs in order to have the greatest impact on people’s lives. By utilizing high frequency vibration motors within ARC, we are able to facilitate larger and clearer writing by stimulating the key muscles in the hand as well as reducing the effort required to move the pen across the paper. ARC prototypes have been trialled and developed in conjunction with fourteen people with the symptoms of Micrographia, demonstrating an overall improvement in writing of 86%.
