Application

Boredom in Context

Objective

  • To use Q-sensor to quantify the physiological state of boredom and compare it withrespect to GSR and facial thermal data

  • 1. Lowers heart rate and respiration rate (Similar to those experienced in sleepiness)

  • 2. Changes electro dermal activity (EDA)

Subjects under boredom tend to be more susceptive to distractions .

Classical example of boredom:

The work of security guards

Motivation

  • Problem:

  • Need to stare at rarely interesting

  • video feeds

  • More susceptible to distractions

  • Any mistake can cost a lot

This highly accurate technology for measuring, temperature, EDA, and motion intensity (X,Y and Z co-ordinates) has never been used with such an objective.

The experimental results show that monitoring of the Q-sensor channels yields similar detecting power to GSR’s. and thermal imaging.

Wearable sensors

- Q-Sensor

Track boredom through physiological variables

Quantify physiological responses

Measurements Technologies

Advantages

Solution:

Combine symbiotic activities with passive monitoring

  • Mobility

  • - Wireless

  • Portable

  • Minimal obtrusive

Wired sensors

- ECG, EEG, GSR

Contact-free sensors

-Thermal imagery

Example of security monitoring

Validation

EAGER Experiment

1. Experimental Design

1. Experiment Design

2. Data Analysis

Symbiotic Activities

Includes 2 wand games, 2 puzzle games, and 1 web browser.

  • The experiment lasts 4 hours (10 sessions)

  • The subject is asked to note suspicious

  • behavior they see.

  • 5 sessions of traditional monitoring,

  • and five with symbiotic activities.

  • The subject is monitored by thermal

  • imaging and contact sensors

  • The experiment lasts 4 minutes

  • The subject is asked to count circles that appear randomly on the monitor

  • The subject is monitored by thermal imaging and contact sensors

  • After every minute an auditory startle is delivered

  • Experimental Timeline

  • The experiment ends about 1 min after the delivery of the third startle

Step1: Extract thermalsignal from maxillaryregion, GSRand Q-sensorsignal

Step2: Down sample the collected data from signals

Step3:Normalize the signals

Step4: Reduce Q-sensor noise

Step5: Perform data analysis [signal correlation, Even Peak Time (ETP) and Even Peak Intensity (EPI)]

Validation Results

EAGER Results

Conclusion

  • Q-sensor can be used effectively to measure temperature, EDA and motion intensity of the psychological state of boredom.

  • Subjects presented higher mean EDA and were more active when exposed to a symbiotic activity.

  • The obtained signal from Q-sensor is similar compared with those of GSR and thermal.

Even Peak Time (EPT)

Even Peak Intensity (EPI)

Summary:

Summary: Mean EDA with activityis greater than without activity
