1. CS 5540 HCI Final Project Designing a Special Needs HCI Hyoungsuk Kong 00311104

2. User Group User group for special need to be people who are too busy to clean their house Students who do not live with family ( stays at school or out of the house until last at night Students who do not live with family ( stays at school or out of the house until last at night People who go to work in the morning and come back late at night People who go to work in the morning and come back late at night Business-man who has business trip often Business-man who has business trip often Seniors who has back-pain or hard to move, so they can not clean the house often Seniors who has back-pain or hard to move, so they can not clean the house often

3. Goal Invent Artificial intelligent vacuum 1. Initialized the data of house structure - Using a xy-coordinates - Saves the every edges of the house 2. Bottom of the vacuum has towel to wipe the floor 3. Top of the vacuum has dust sucker and spray for fresh air

4. How it works When user operate the vacuum first time, he/she installs every edge of the house When user operate the vacuum first time, he/she installs every edge of the house Vacuum system will save those edges on the coordinate system Vacuum system will save those edges on the coordinate system From next time, it operates itself with the edges on the coordinate system From next time, it operates itself with the edges on the coordinate system

5. Scenario 1. ‘A’ went business trip for a while 2. Before he went out, he set time to clean house on the vacuum 3. At the time the user set, vacuum cleans house everyday 4. Spray and dust sucker are operated every one or two hours for keeping fresh air (user can reset frequencies)

8. System Vacuum uses the xy-coordinate Vacuum uses the xy-coordinate It calculates the point that it moved through It calculates the point that it moved through It memorizes the point by calculating the movement distance and vectors It memorizes the point by calculating the movement distance and vectors

10. Peer Review – Taeho Kim What about power lines? What about power lines? - Isn’t the power lines border the way it moves? What about obstacles? What about obstacles? How does it take care furniture in the house? How does it take care furniture in the house?

11. Modification I add the battery on the vacuum I add the battery on the vacuum It will be charged on the vacuum charger, then it does not need the power lines It will be charged on the vacuum charger, then it does not need the power lines I load the obstacle sensors on front, right and left side of the vacuum, so it can notice if there is obstacles or not I load the obstacle sensors on front, right and left side of the vacuum, so it can notice if there is obstacles or not

13. Re-evaluation The changes helps the user use them The changes helps the user use them It makes better performance and more reasonable It makes better performance and more reasonable

14. Conclusion Do you have problems with dirty air in your house. Do you have problems with dirty air in your house. You don’t have time to clean house You don’t have time to clean house You need a fresh air everyday You need a fresh air everyday This vacuum will help you to have fresh and clean environment in your place This vacuum will help you to have fresh and clean environment in your place
