2. Contemporary Life Style • Prolonged use of computer • Professions requiring prolonged sitting – Banking, Telephone operators, students, authors, doctors, pharmacist, architect, Civil Servants – secretaries, lawyer, tailor, designer etc.) • Handling of multiple objects at a time – keyboard, mouse, phone, mobile phone, writing pad, pen etc. • Long driving • Long meetings Giriraj Goyal, Samsung Electronics

3. Body postures while using computer Giriraj Goyal, Samsung Electronics

4. Body postures while using phone and computer Holding the phone between the ear and the shoulder places a lot of stress on the joints and muscles Giriraj Goyal, Samsung Electronics

5. Repercussions of incorrect body postures • Back pain • Neck pain • Arm and wrists pain • Shoulder pain • Eye strain • Disorders of soft tissue (muscle knots, muscle tension and contractions, circulatory disorders, overuse disorders) • And list goes on…… Giriraj Goyal, Samsung Electronics

6. Back Pain • Lack of support from your chair • Improper fit of the chair, or the improper type of chair for computer use • Sitting slumped • Feet not touching the ground • Prolonged sitting, without a break • Over reaching for the keyboard or mouse Giriraj Goyal, Samsung Electronics

7. Neck Pain • Viewing a monitor placed too low or viewing a document on the desk • Looking up at a monitor that is placed too high • Looking over to one side to view a monitor or copy from a document • Jutting the chin forward to view a screen or copy from a document. Giriraj Goyal, Samsung Electronics

8. Arms and Wrists Pain Giriraj Goyal, Samsung Electronics

9. Ergonomics suggestions – 1/2 • Correct posture and positioning of the body • Position of keyboard and mouse • Correct position of the chair • Correct position of the computer screen • Correct usage of mouse and keyboard Giriraj Goyal, Samsung Electronics

10. Ergonomics suggestions – 2/2 As suggested by an ergonomics expert Giriraj Goyal, Samsung Electronics

11. Need for BAN – 1/2 Present Solutions: • Computer users try to follow the instructions of an ergonomics expert. • Ergonomics Software to help users to take regular breaks, get reminded of correct posture and do regular stretches. Giriraj Goyal, Samsung Electronics

12. Need for BAN – 2/2 Problems with present solutions: • It is easy to adjust the height of the chair, height of the screen and re-arrange the desk. But, It is difficult to follow the instructions aimed at your body. • Ergonomics software are not intelligent enough, they are not aware of state of user and state of work environment. It can annoy user persistently with pop-up messages. Giriraj Goyal, Samsung Electronics

13. BAN A VIABLE SOLUTION The solution using BAN could consists of • The network component • A wearable costume with wireless sensors placed at appropriate positions, sensors in chair, desk, and a gateway, form a body area network. • Verification component • This entity takes information from BAN network to check the correct posture of a body by analyzing the collected data. • Message delivery component • This entity notifies a user with a simple text or audio message or AV message. It could just be a warning message for wrong body posture or with a possible correction. Giriraj Goyal, Samsung Electronics

14. Requirements • Location awareness techniques • Low data rate • Ideally no false alarm and no positive miss Giriraj Goyal, Samsung Electronics
