Techniques for Recording and
Analyzing Posture and Gesture as
a Means of Inferring Students’
Emotional States
1
Learning & Emotion Lab
•  Focuses on uncovering the relationships between students;
learning and their emotional (i.e., affective states. The
research goals include refining psychological theory and
developing educational applications, such as emotionally
adaptive learning environments.
•  Dr. Roger S. Taylor
•  Zachary Bradley

Measuring Affect: Through Facial
Expression - Boredom
AU 27 + 64 – Mouth Stretch
+ Eyes Down
AU 43 + 64 – Eye Closure
+ Eyes Down
Neutral AU 27 AU 64AU 43 AU 55

Examples of Facial Expression
Boredom
Happiness/Excitement
Confusion
Calmness/Neutral
5
Affect Sensors: New Setup
• Facial Displays
• Webcam
• Human & Computer Coding
• Posture
• Replace Pressure Sensitive Chair with Kinect
• Affect Map
• Java Implementation
• Mobile Devices (hopefully coming soon)
Current Research Projects
Posture Analysis
•  Determining students’ emotional states through
their postures.
Facial Analysis
•  Determining students’ emotional states through
their facial expressions.
Self-Report Assessment
•  Determining students’ emotional states through
the Affect Map self-report instrument.
6
Utilizing the Kinect Motion
Sensing Input Device to Record
Students Affective States
7
Assessment Techniques
•  Internal - Observations Reference Frame –
Self-reports – Affect Map
•  External - Observations Reference Frame –
Behavioral Traces – Kinect Device

Affect: Theoretical Background
•  Core Affect Theory (Russell, 1980, 2003; Russell & Barrett, 1999
• Dimension 1: Activation Represented vertically, with higher levels of energy
toward the top and lower levels of energy toward the bottom
• Dimension 2: Valence Represented horizontally, with “positive” feelings
(pleasant) toward the right and “negative” feelings (unpleasant) toward the left
10
• Measurement about every minute
• Activation: Level of Energy (Vertical)
• Valence: Level of Pleasure (Horizontal)

Kinect Device
•  Motion sensing input device
•  Records participants postures and gestures
and exports joint positional coordinates X,
Y & Z to a .CSV
11
Kinect
12
Methods
•  Participants: 37 SUNY Oswego
undergraduates, 2 males, 35 females
•  Materials: Algebraic Problems; levels of
difficulty = Easy, Medium & Hard
•  Procedure: Participants attempted to answer as
many algebraic equations as possible in one half
hour.

Open Sesame
14
Data Visualization
•  Students’ emotional states over time
•  Distance from screen (meters)
•  Emotive State (Valence | Activation)
•  Problem difficulty (Easy | Medium | Hard)
