Children who are suffering from mental disabilities struggles to keep up with their studies, this then result in them being unable to learn the proper studies and left them in a disadvantageous position. Studies have shown that students with mental disabilities such as autism might still be able to follow basic studies more slowly. Some studies have indicated that children have far more greater responds to studies which include bright colors. The reason for this is because special needs children have low attention span. For this reason, an interactive learning system needs to be developed. This study will try to make an interactive learning system with a flex sensor. The interactive learning system will be made as a mobile application. This application will be made by using a software named MIT App Inventor. A multiple-choice question will be used in this study with interesting photos. To answer the multiple-choice question, a flex sensor which has been attached to glove, will be used to select the multiple-choice answer. The subject must bend their finger to pick the multiple-choice answer. Testing this assistive device with special needs children has yielded a satisfactory result, of the 12 questions displayed in the application, 7 multiple choice questions have been successfully answered correctly for the first subject and 8 multiple choice question have been successfully answered correctly for the second subject.
