This research focuses on developing a new assistive device that employs sensing and feedback to prevent urine from splashing. This device is mainly designed for boys or disabled people who urinate while standing in front of a sitting toilet. The device consists of two major components. Firstly, a transparent screen connected to the toilet cover prevents urine from splashing. Secondly, an IC alarm device that detects the urine distribution and alerts the user serves to notify, remind and provide feedback to the user about splashing. Based on on-site testing with seven children and students with special needs, the protective screen can effectively prevent urine from splashing up to 48%; the urine distribution alarm has an accuracy rate of up to 86%. The application to patent this device has already been filed, and this creative product will be mass produced in collaboration with manufacturers.
