Measurement plan

The goal of this measurement plan is to create a guideline for the two experiments that will be carried out. This will result in a smoother transition between acquiring the materials necessary for the set-ups, performing the experiments and exporting the data.

With the first experiment we will be verifying if the impact of different circumstances results in a deviant output. What will a difference in distance, angle or light/dark ratio do to the results?

With the second experiment we will be verifying the performance of the Noldus software by testing a range of basic emotions, by using certain movie segments. Experimental subjects (varying in age) are positioned in front of a camera, while being exposed to fragments of themed video material. Key is to execute the experiments with comparable circumstances.

Experiment 1

List of equipment:

1. Laptop with Noldus software ‘FaceReader 7.0’

2. Webcam

3. Lightsource

4. Chair

5. Table

Experiment 1.1: varying distance, constant angle, constant light/dark ratio

Steps to take:

1. Turn on laptop and start ‘FaceReader 7.0’

2. Start ‘new project’

3. Select ‘new participant’

4. Select the connected camera

5. Take place in front of the laptop, with the face pointing directly towards the webcam

6. Start an analysis

7. If the software recognizes the face, increase the distance between participant and webcam

8. Repeat till the maximum allowable distance is reached

9. Write down this distance

Experiment 1.2: constant distance, varying angle, constant light/dark ratio

Steps to take:

1. Turn on laptop and start ‘FaceReader 7.0’

2. Start ‘new project’

3. Select ‘new participant’

4. Select the connected camera

5. Take place in front of the laptop, with the face pointing directly towards the webcam

6. Start an analysis

7. Let the participant turn her/his head slowly to the right, until the face cannot be detected anymore

8. Write down this angle

9. Repeat this also for the directions, left, up and down

10. Increase the distance between participant and repeat until the face cannot be detected anymore

Experiment 1.3: constant distance, constant angle, varying light/dark ratio

Steps to take:

1. Turn on laptop and start ‘FaceReader 7.0’

2. Start ‘new project’

3. Select ‘new participant’

4. Select the connected camera

5. Take place in front of the laptop, with the face pointing directly towards the webcam

6. Start an analysis

7. Make the room as dark as possible and slowly turn on the lights

8. Write down when the face is first detected and at which point (if necessary) it cannot be detected anymore

9. Repeat for turning the lights of

Experiment 2

List of equipment:

1. Laptop with recoding software

2. Webcam

3. Lightsource

4. Chair

5. Table

Experiment 2.1: Varying experimental subject with constant circumstances

Steps to take:

1. Turn on laptop and start ‘FaceReader 7.0’

2. Start recording software

3. Place the experimental subject in front of the laptop, with the face pointing directly towards the webcam

4. Start the first fragment with emotion ‘Happy’

5. After two minutes, stop the fragment

6. Start an analysis

7. Ask the participant how he felt during the experiment and write it down

8. Repeat this for the fragments with emotions ‘Angry’, ‘Sad’, ‘Fear’, ‘Disgusted’ and ‘Surprised’.
