Hybrid Approach of Augmented Classroom Environment with Digital Pens and Personal Handhelds Motoki Miura Susumu Kunifuji Japan Advanced Institute of Science and Technology （JAIST） http://css.jaist.ac.jp/~miuramo/ KES2006＠Bournemouth 2 Outline “Augmented Classroom” project System “AirTransNote” What is “AirTransNote” ? What was lacking for “learning support system”? How we changed the system? What’s the typical usage in lecture? 3 What is “AirTransNote” Devices: Digital Pen and PDA(WLAN) Capture student’s handwritten note on paper, and transmit to teacher’s PC immediately Share by Projecting Store, Analyze, and Review the note Student can get feedback via PDA 4 ATN Mediator(2)(student) The sensors detect the ultrasonic waves, and calculate position data of the pen tip (4) PDA transmits the data via wavelan (3) The data is sent to PDA via infrared connection (1) Tap the pen tip on the paper, ultrasonic wave is diffused 5 ATN Manager (Teacher) 6 Start video 7 Purpose of AirTransNote Basic Functions： Capture students’ note and transmit Teacher can show the note with projector Reduce times to re-write on Blackboard Purpose： Facilitate communication between class members Encourage active learning A successor of response analyzer (ex. EduClick[Huang 2001]) Feasibility Study 40 1st-y high school students (15-16 yrs-old), Math class, March 2004 8 9 10 Teacher’s Remote for direct note selection 11 Our concept: “Augmented Classroom” Enhance the ability of classroom with calm technology Based on ubiquitous/pervasive computing paradigm KBD，Mouse→Paper and Pen, RFID However, we should focus on “learning effects” of the system 12 Re-design of AirTransNote with consideration of learning Feedback/interaction is the key factor Shift to “Collaborative learning” Limitation of feedback with papercentered approach Make full use of PDA for giving feedback Complementary use PDA and Paper →Improve shortages the system to cover the 13 Four learning effects enhanced by AirTransNote Self Reflection Interaction among Students Student Interaction between teacher and Student Teacher Student Interaction between System(Mediator) and Student Mediator 14 Four learning effects enhanced by AirTransNote Self reflection by student Interaction b/w system⇔student Feedback depends on student response Interaction b/w teacher⇔student Re-check note on PDA Recognition of student’s progress and learning status Interaction among students Sharing/Browsing notes with PDA Tagging/Annotating 15 16 Checking note from PDA 17 System improvenents Previewing with paper image context on PDA Ease of checking Connect with handwriting recognition engine Support for various responces Feedback editor for teacher We attached web server to teacher’s system For checking progress (by teacher) For browsing student note images (by teacher/student) 18 Advantages of Digitized note △ Show idea with note drawing ○ Capture drawing alone We can use document camera Flexiblity of showing （ex. overlap to compare） ○ Capture time series of note Reproducing note with writing order Ex. Check order of Chinese character Ex2. Show direction of electric current flow (電流方向) Writing order may reflect thinking process 19 Experiment (20 graduate students, geometry test and IQ quiz with sound feedback) 20 Finding Realtime feedback is accepted by student Feedback may alleviate stress Student can know whether his/her answer is correct or wrong before making public. Further experiment is required 21 Conclusion Re-design of AirTransNote System for facilitating communication in lecture Improved to support “collaborative learning” Future work: Conduct experiment to check “active learning mind” with various conditions 22 Thank you!!
