Stress

Methods for individual/group stress reduction:

  1. Sensors: HRV, EEG
  2. Inputs: Music, light, VR, adaptive ambience
  3. Strategy: (i) feedback control of light/sound at individual/room level; (ii) VR: Mindfulness, gratitude, guided imagery

 

Stress Reduction with Music Modulation

  1. Focus on individuals.
  2. Sensor: PPG, compute HRV (SDNN)
  3. Input: Tempo-modulated music, via feedback of stress
  4. Controller: Proportional-integral (PI)
  5. Results: Feedback control reduces stress during a type of Stroop test, where music or no-music results in increases in stress. For more information, see Andrew Fu's thesis and defense slides.

 

Identifying Child Isolation in a Preschool Classroom

  1. Isolation seems to occur due to choices by a child (move away from group, draw inward) or due to exclusion by other children. Each may cause stress in the child.
  2. Computer vision approaches to detect and identify cases where children are isolated by physical distances.
  3. Results: Use of an isolation/social clustering score, some validation that it succeeded. For more information, see Joey Chiu's thesis and defense slides.

 

Adaptive Ambience for the Classroom:

  1. College of Engineering / Schoenbaum Famiy Center collaboration, focus on preschool classrooms, toxic stress due to childhood trauma
  2. Funded by the Battelle Engineering, Technology, and Human Affairs endowment.
  3. Sense child HRV (watches), algorithmic computations (controller), and modulation of ambient light and sound for stress reduction.  Also, sense child voice (see some progress by Feifan Jia here) and location (see above).
  4. In progress, led by Dr. Hugo Gonzalez Villasanti at SFC, Crane Research Ctr.

 

PTSD:

  1. Understanding symptoms, prevalence, treatment methods, and neuroscience
  2. Research on novel treatment methods based on coordinated sound/light modulation.
  3. In collaboration with McKayla Tassy, neuroscience major
