1. REU Summer 2014 A Video Interface For Elderly Patients to Review Depth Videos Over Network Gary Grimm Dr.Skubic Zac Crane Moein Enayat i

2. 2 Abstract Users of the MU elder-care program desire the ability to review videos stored in a server at MU over the internet. Currently, there exists an interface that is intended for researchers and medical technicians to review data. This interface is rather complicated and represents data in a very technical manner that elderly users may not find appealing. We use data visualization, easy-to-access and simple layouts, and bandwidth detection to make the interface more accessible and useable for the elderly.

3. 3 Our Solution ● Create an easy to use, accessible video interface for elderly patients to access and review Kinect depth videos ● Detect available bandwidth (BW) to determine the quality of the video to be sent – Utilize different quality videos to allow loading and downloading on various BW qualities.

4. 4 Motivation ● Elderly patients have a difficult time with technology – We need to make it more accessible for them! ● Multiple speed capabilities are also important – Devices can range from dial-up (56k) to Google Fiber (1,000 Mbps)!

5. 5 Definitions ● Bandwidth – Available communication resource in bits per second. ● Accessibility – The extent to which a product is available to as many people as possible. ● Bit Rate – The number of bits processed per unit of time.

6. 6 Road map ● Research about elders – What are their limitations? – How do they best interact with technology? ● Research accessible web pages – What are the components that make a web page accessible? – How can we implement these features?

7. 7 Road map Con't ● Tie the research into a web page for elders – Take these considerations and create something new. – Make it better for a select group (the elderly).

8. 8 Background ● Utilizing the.MP4 file extension – Easily compressed. – Integrates easily in all Web Browsers that we are using (FireFox, Chrome, IE, Safari). ● Bandwidth capabilities of various devices – Dial-up, 2g cell phone, 3g cell phone, wifi, etc...

9. 9 Background Con't ● Accessibility – This is the most important feature of the web page. – If elderly patients cannot easily use the interface, then this aspect of the project has failed. ● Bandwidth Detection – Created a function to test the BW.

10. 10 Method ● Calculate the download speed – Video size / Bandwidth = Time

11. 11 Method Con't ● Hosted on the Elder-tech web server – Security of files that are being accessed

12. 12 Previous Work ● Created a functioning web portal ● Dynamically loads videos from the server into a playlist

13. 13 Previous Work Con't (Previous Web Page)

14. 14 Previous Work Con't ● Controls are not labeled – The play button is the built in one for the video player – No next button ● Page does not fit the browser – Have to scroll to see everything on the page ● Small buttons and text

15. 15 Our Contribution ● Redesigned the video interface: – Ease of use and accessibility for the consumer instead of the researcher ● Allow Bandwidth detection – Use this in order to improve the Quality of Experience

16. 16 Our Contribution Con't (Current Web Page)

17. 17 Our Contribution Con't ● Large buttons and text – All player functions have their own button that is clearly labeled – We have a skip to movement button ● The page fits the browser without the need to scroll ● Used a date/ time picker that did not require typing ● Few extraneous options and simple layout

18. 18 What We Have Learned ● Learned about how to implement various API's and frameworks ● DB queries and how to implement them into a web page ● DB management ● Reinforced our knowledge of how networks work ● Used Tunneling and SSH to access a secure server

19. 19 What We Have Learned Con't ● Learned and implemented HTML, CSS, Javascript, JQuery, AJAX, PHP, MySQL and the Google Visualization API ● Learned about bandwidth and various ways to detect it/calculate it ● Most importantly, We learned how to be an effective team

20. 20 Conclusion ● We have created an intuitive and easy to use web page that is designed for elderly users and their limitations ● The web page has a simple and easy to understand layout ● Bandwidth detection is working

21. 21 Future Work ● Create a log-in page before the video player ● Possibly create a chart to display movement ● Create markers for the video player ● Refine the web page layout based on feedback
