Project proposal

1. Project proposal BEHAVIORAL CORRECTION ROBOT FOR TIC-DISORDER • SONGHUI RYU, YEONJU OH • COMPUTER & INFORMATION TECHNOLOGY, PURDUE UNIVERSITY • CNIT 581 – Introduction to Assistive Technology and Robotics • FALL 2016

2. TOPIC • What is tic disorder • Tics are abrupt, uncontrollable movements or sounds • that deviate from a person’s normal gestures.

3. TOPIC • Tic disorder and Tourette syndrome • Accompanied by • Obsessive-compulsive disorder (OCD) up to 50% • Attention-deficit hyperactivity disorder (ADHD) 30-50% • Mood disorder

4. TOPIC • Why? and how to cure Causes are not yet figured out. It could be liked to - inheritance: Genetic mutation - neurotransmitters: Dopamine, serotonin - functional abnormalities in the brain: frontal lobe - hormone: boys are more prone to tics - birth problem - environment (but not solely)

5. TOPIC • Why? and how to cure Transient tics often goes away without treatment - Family members and teachers shouldn’t call attention / scold them - Stress makes tics worse and more frequent! In other case, Behavioral therapy - To train to manage their tic symptoms and reduce the frequency - Massed practice, relaxation technique, awareness training, self-monitoring, etc. - Effective for transient tic disorder Mental therapy - To control emotions and think positively, confidently - Shouldn’t be primary method Medication - For chronic tic disorder or TS, to control neurotransmitters - Effective for 70-80% of patients

6. MOTIVATION • It can be problematic • Patients can have problems with social activities • Tics can physically hurt patients & Tics may be during sleep • But, • Overall, treatments can help tics. • - Vocal tics can go away, motor tics can get better • - Tics most severe between 7-15 years old of age • - 30-40% of TS patients are cured completely or gets to moderate level • What if somebody helps them control themselves?

7. OBJECTIVE • Developing robot that helps behavioral therapy for tic-disorder • Patients with tic-disorder can have difficulties with behavioral therapy • - They may not recognize if they are doing tics currently • Robot can be an assistant that remind them stopping / controlling tics • - catches motor tics by motion recognition with camera • - catches vocal tics by voice recognition with microphone • It shouldn’t bother patients but just be a friend!

8. LITERATURE REVIEWS • Body Motion Detection • Using depth camera (Kinect) • Construct a motion library based on motion data • Utilized / Improved ‘Dynamic Time Warping(DTW)’ algorithm • Find a difference between two different sets to match a length of the vector sequence Calculate difference Training Data Vision / Vocal Data Feature Detection Look up library [4] Li, N. et al. 2015. Study on Action Recognition Based on Kinect and Its Application in Rehabilitation Training. 2015 IEEE Fifth International Conference on Big Data and Cloud Computing (BDCloud) (Aug. 2015), 265–269.

9. LITERATURE REVIEWS • Facial expression detection • Measure user’s emotional engagement when looking at smartphone • Extract the geometry of the face found in a video • Calculate the angle between lip and nose to classify facial expression • In my project,detect and utilize more various facial landmarks and geometry [5] Mankodiya, K. et al. 2013.

10. LITERATURE REVIEWS • Tic Disorder Treatment • Tic awareness -> transform the habit to new action • Group 1: comprehensive behavioral intervention • Group 2: supportive therapy and education • Measure the improvement about reducing tics and tic-related impairment • Conclusion Efficacy increased Habit Reversal Training Supportive Therapy [6] Piacentini J et al. 2010. Behavior therapy for children with Tourette disorder: A randomized controlled trial. JAMA. 303, 19 (May 2010), 1929–1937.

11. Approaches & plans • Approaches • Except medical treatment, Habit reversal training (HRT)is the most effective way to reduce tic and tic-impairments. • If a program detect motion repetition, a robot will give a notification to users as a sound output. • Robot suggests habit reversal training action when users have tic disorder symptoms Motion / Voice Recognition Improvement of Symptoms Kinect + MicRaspberry pi Give alerts HRT User

12. Approaches & plans • plans

13. Equipment list • Raspberry pi • XBOX 360 Microsoft Kinect Sensor • USB Microphone for Raspberry pi • Speaker for Raspberry pi
