- LabQuest 
- LabQuest App 
- Vernier Electrocardiography (EKG) Sensor

|Fig 1. Position of electrode tabs and EKG clips|
1. Allow the subject to rest for 10 mins
2. Connect the EKG Sensor to LabQuest.
3. Attach 3 electrode tabs to the subject’s arms, as shown in Figure 1.
a. Place a single patch on the inside of the right wrist.
b. Place a single patch on the inside of the right upper forearm, distal to the elbow.
c. Place a single patch on the inside of the left upper forearm, distal to the elbow.
4. Connect the EKG clips to the electrode tabs as shown in Fig 1.
5. Measure the heart rate of the subject for 10 minutes.
a. Have the subject sit in a relaxed position in a chair, with his forearms resting on his legs or on the arms of the chair.
b. Start collecting data only when the subject is properly positioned.
6. Start the selected game.
7. Measure the heart rate of the subject for 10 minutes.
8. Save the graph.
9. Change the electrode tabs.
10. Create a new graph and start the next game.
11. Repeat Steps 6-8 for every game played.
12. Repeat Steps 1-9 to ensure the reliability of the results.
13. Repeat Steps 1-11 and on different subjects.
2.4 Risk Assessment and Management
- Subject’s eyesight might deteriorate if he games for a long period of time
- Subject may experience discomfort after playing
- Subjects neck may ache
- Do not let the subject game for a long time (only 10 minutes per game, rest after 30 minutes)
- Make sure the subject is feeling well during and after gaming
- Make sure that the subject does neck exercises before and after the test
2.5 Data Analysis
1. Print the graphs out with the y-axis 0.5≤y≤5.
2. Put the highest and lowest point of the graphs in a table
3. Compare the 4 graphs and see if there are changes in the heart rate.
4. Repeat with the other subject’s graphs.
