CSE 463 Final Question and answers
rated A+ 2025
When is it a good idea to measure Partial Success in Research Study? -
correct answer A task which requires multiple steps, like placing tulips in the
correct order and then adding a gift message, requires a partial score, since
someone could get 80% of the way without succeeding in a task. **

What inputs does the HoloLens interface consist of? - correct answer *1.
Gestures -*
Engineers are fine-tuning a feature called "holding" that would allow you to
grasp and manipulate holographic objects. Opening your hand would take you
back to a home screen. The sensor can detect the wearers hands and a user
can interact with whatever he sees by touching it.
*2. Voice -*
Microcrophones in the device capture voice commands.
*3. Gaze -*
Sensors track where the wearer is looking and adjust the display. The depth
camera has a field of vision that spans 120 by 120 degrees.
*4. Motion -*
Sensor detect wearers movement.
*5. Buttons -*
Buttons on the ride side of the HoloLens allow users to adjust the volume and
to control the contrast of the hologram.
Advantages of HoloLens - correct answer 1. Ease of use
2. Responsive to presence of people
,3. Enables easy instruction, even for the untrained person
Disadvantage of Microsoft HoloLens - correct answer * Fragile
* High Maintenance
* Distracting
* Privacy Concerns
How do humans express affect? - correct answer Visible to the naked eye
Facial expressions
Body language
Voice pitch and volume
Skin reactions (e.g., sweat)
Not evident to the naked eye
Brain activity
Visual Attention and pupil reaction
How humans perceive and understand affect? - correct answer *Through our
five senses
We process experiences mentally and consider previous experiences
What must Affective Computing do in order to mimic human affect? - correct
answer We must create systems and devices that allow us to: ..
1. Recognize
2. Process
3. Represent
4. Understand
,5. Deliver (Stimulate)
.. human affects.
A Eye Tracking Biometric Sensor tracks: - correct answer 1. Fixation
(sequence of fixations as well)
2. Gaze (gaze replay)
3. Pupil Dilation
4. Visual Attention (area of interest)
A Galvanic Skin Response (GSR) Biometric sensor tracks: - correct answer
Stress/Emotional Intensity
A Facial Recognition Biometric sensor tracks: - correct answer 1. Anger
2. Contempt
3. Disgust
4. Fear
5. Joy
6. Sadness
7. Surprise
A Brain Wave (EEG) Biometric Sensor tracks: - correct answer 1.
Engagement
2. Excitement
3. Focus
4. Interest
5. Relaxation
6. Stress
, **Headset considers a ML (machine learning) algorithm that define the
emotion detected based on the activity of different zones of the brain.**
Multimodal System - correct answer A system using multiple Biometric
Systems
Challenges with Multimodal Systems - correct answer 1. Data size
2. Sample Rates
3. Synchronizing Data
4. Defining models and algorithm which incorporate data from diverse
sources.
**Example: Modeling behavior
- We can use the info from eye tracking and EEG to create models (using ML)
related to consumer behavior; e.g., willingness to buy, reaction to prices,
navigation in diverse layouts and the emotional reaction to these layouts.**
Advantages of a Passive Biometric Measurement System - correct answer *
Non-intrusive
* Unbiased
What is nominal data? - correct answer Data that can be placed in categories
(colours, Type A/B personality, types of attachment style).
What is ordinal data? - correct answer Data which is placed into order/ranked
but the distances between the scores is not known
