Background:Over the past 2 weeks, we conducted an online user survey.

Objective:• Find out more about our respondents’ demographic information.• Understand their computer usage frequency and activities.• Also try to test their level of knowledge for basic eye care.

Users:• 28 respondents• Aged between

Hours spent on computer/laptop per usage

Activities performed on computer/laptop

What should be the proper distance between your eyes and the monitor?

Recommended distance by the Health Promotion Board is 50 cm.

At what age did your eye problems start to develop?

Did you know?The earlier myopia starts, the greater the likelihoodthat it will progress in severity as a child grows.

• Concerned working parents who have no time to properly monitor the computer usage frequency of their children.

• Also extended to health conscious working adults who are seeking help to take proper care of their eyes while working long hours on the computer.

• An initiative by 4 NUS students from different faculties.

• All of us share the same vision and goal.– to improve eye-health through

• creating awareness of the prevalent of eye problems• create devices to aid in this awareness.

• We shall elaborate more on the design of our product.

• This device looks like a webcam.– Sits on top of your computer screen.

• Scans & detects your eye iris with every use.

• Triggered by dilation of the iris or “gaze”, which signify eye fatigue.

• System will adaptively dim the brightness of the computer screen according to the energy level of the user’s eyes.

• LED Light Indicator

• Adaptive dimming

• Usage Report Log (to be shown later)

Conclusion + Q&AConclusion + Q&A

To begin a session on the i.Health system, turn on the computer with the webcam attached

A battery icon resides onscreen to indicate the level of eye fatigue

When the user’s eye energy level falls below a set threshold, the screen brightness is stepped down to reduce glare and inform the user of the state of his tired eyes.

Users can click the icon at anytime to set the system to hibernate and take a break.

Users can choose to view logs of their previous sessions. Sessions are started and ended as soon as the users eyes are detected and after the computer is left alone for a time.

Eye blink based fatigue detection for prevention of Computer Vision Syndrome

• Divjak, M. & Bischof, H.

• Use frame per seconds to determine eye blinks and from such analysis, determine the level of eye fatigue.– Correlation between eye blink & eye fatigue.

• Experiment conducted to demonstrate such correlation.

A Robust Iris Detection Method of Facial and Eye Movement.

• Kashima, H., Hongo, H., Kato, K. & Yamamoto, K.

• Division of face region into eye & mouth regions, then using Hough Transform to define iris positions.

• 98% for eye region detection

• 96% for iris detection.

• Our team has conducted a market research to identify eye care devices/products that may coincide with what we are doing.

• We found the following:– eyeRelax– Eye Care Massager

• Mainly focused on eye therapy, not eye hazard reduction (which is our main objective).

Conclusion + Q&AConclusion + Q&A

(+)• Prevention is better than cure.• Non-obtrusive to users’ activities.• User friendly – easy to use & easy to install.• Possibly cheap & definitely portable.

(-)• Some observers find it intrusive to user’s lifestyle.• Problem of detecting multiple iris from multiple users.• Lack of appeal to the mass market?

• Mobile synchronization for parents

• Extend project to television display screen

• Holistic security system

Conclusion + Q&AConclusion + Q&A

• Currently our project, i.Health is a unique initiative (never been done before).

• Tackles root of eye problems instead of treating symptoms

• Hugely beneficial to all computer users.

• May we reemphasize: if you find the product intrusive, it may not be targeted for you.

1. The problem of intrusiveness of the technology is inevitable. What are some ways in which we can reduce or possibly, remove users’ frustrations in using this product?

2. What are some ways (you would suggest) to encourage users to improve their eye health and/or eye care habits?
