1 CS2310 Fial Project Loghao Li Term Project Report Itroductio I this project, I worked o expadig exercise 4. What I focused o is makig the real gesture recogizig sesor ad desig proper gestures ad recogizig method that are optimal for patiet i order to help them to report their emergecy to the emergecy maager. System Desig The followig graph illustrated the expaded system based o exercise 4. There are three compoets i the system: Gesture Recogizig Sesor, Emergecy Maager ad Homecare Staff. I Gesture Recogizig Sesor, there is a Kiect sesor ivolved for gesture recogizig. I the followig sectio, there are more specific descriptio about each compoet. Compoets Gesture Recogizig Sesor This compoet works to detect gesture from the patiet as a sig of emergecy message ad sed it to the emergecy maager. l Sesor (Kiect) I used Kiect for gesture recogizig, sice it ca easily detect users movemet i a very big area ad very specifically described the movemet as data for developers to use. It ca detect body movemet described as movemet of skeleto movemet. It ca eve detect had gesture, which give developers more possibilities.

2 l Gesture (Had gesture) Based o my uderstadig ad thikig i patiets prospective, I choose to use a series of had gestures for emergecy message. The series of had gestures ca be illustrated like followig: Patiets will eed to use their right had to do ope had, closed had alteratively for seve times as a represetatio of emergecy message. I oly used right had, it ca defiitely be expaded to recogizig either had easily. Patiets eed to do these had gestures cotiually, otherwise, if the patiet stopped i the middle, it will ot be recogized. A threshold of time iterval betwee two differet had gestures is used to achieve this. I use 2 secods as threshold. It ca be chaged to be optimized for patiets. Also after patiet successfully set a message, there will be a very short time iterval that patiet caot sed message. It is desig to avoid patiet sed extra message that ot iteded sice it is ot a good desig for patiets to cout how may gestures they did. If patiets are i a severe situatio, they ca keep doig the series of had gestures that ca across the time iterval, sice it is very short, i order to sed more emergecy message as a represetatio of severe situatio. Whe a series of had gestures is recogized as emergecy message, a visual feedback will be displayed o scree. If they saw that, they ca stop. This feedback ca be replaced by ay type of feedback that are optimal for patiets. There are several reasos why I use this series of gesture: It it easy to performed. Whe they are i emergecy, they may ot be able make a very big movemet. This had gesture did t requiremet patiet to move a lot ad it is simple eough to do. Fault tolerat. Sice it requires several repeats of had gestures ad usig time threshold to cotrol, it is hard to make a false alert from ormal activities. l Implemetatio The Kiect program is writte i C#. Parts of the program is ispired by a ope source project provided by Vagos Ptereas (Ptereas, 2014). I implemeted all the logical ad cotrol uit for gesture recogitio ad modified the display for visual feedback. The Gesture Recogizig Sesor compoet is writte i Java ad followed the requiremet of the SIS system. The coectio betwee Kiect program ad Gesture Recogizig Sesor compoet is socket based. Kiect program will work as a cliet to sed message to Gesture Recogizig Sesor compoet as server.

3 Emergecy Maager This compoet as a super compoet ca geerate differet solutios after receivig Emergecy message from Gesture recogizig sesor. 1. Message came as the first time The emergecy maager will sed a message to homecare staff to tell them to call the patiet. 2. Message came ot the first time The emergecy maager will sed a message to homecare staff to tell them to visit the patiet After a message is proceed, a timer will start a cout dow, if there is o message comig after previous message for certai amout of time, which is a threshold, the emergecy maager will clea the history so that if a message comig, the message will be treated as the first time attempt. Here is the scree shot to show how Emergecy Maager process the emergecy message. Homecare Staff This compoet will work to do the job that emergecy maager asked. Whe it received the message, it will display it i a pop up widow. 1. Message: Call The Patiet It will display call patiet iformatio o scree to homecare staff ad wait for the respose from them to see if the patiet picks up the phoe. if the feedback is patiet did t pick up the phoe, it will display visit patiet iformatio o scree to homecare staff.

4 2. Message: Visit The Patiet It will display visit patiet iformatio o scree to homecare staff. Scree Shot to show how Homecare Staff compoet works

5 Demostratio There is a Demo video o YouTube, which demostrate how my program works: Lik to The Source Code Passible gems 1. Lik to YouTube live demo 2. Iclude the Kiect as a sesor for gesture recogizig 3. Come up a easy to use had gesture for emergecy message ad recogizig algorithm 4. Graphical display of message i Homecare Staff compoet 5. Lik to the source code for this project.
