Dr. Joon-Ho Choi
Human-Centered Environmental Controls: Bio-Sensing Environmental Control for Ensuring Human Thermal Comfort in the Building Environment

Dr. Choi’s research focuses on developing an integrated human-centered framework for intelligent environmental control in a building. The physiological signals of the occupants, as well as their ambient environmental data, are integrated by using wearable sensing agents and embedded environmental sensors. This novel concept embodies an integrative approach that promotes viable bio-sensing-driven multi-criteria decisions for determining building thermal and lighting system controls. This interdisciplinary research across Engineering, Medicine, and Architecture has a large potential to enhance energy efficiency and occupants’ wellbeing by optimizing building environmental control performance.

Use Your Cell Phone as a Document Camera in Zoom

  • What you will need to have and do
  • Download the mobile Zoom app (either App Store or Google Play)
  • Have your phone plugged in
  • Set up video stand phone holder

From Computer

Log in and start your Zoom session with participants

From Phone

  • Start the Zoom session on your phone app (suggest setting your phone to “Do not disturb” since your phone screen will be seen in Zoom)
  • Type in the Meeting ID and Join
  • Do not use phone audio option to avoid feedback
  • Select “share content” and “screen” to share your cell phone’s screen in your Zoom session
  • Select “start broadcast” from Zoom app. The home screen of your cell phone is now being shared with your participants.

To use your cell phone as a makeshift document camera

  • Open (swipe to switch apps) and select the camera app on your phone
  • Start in photo mode and aim the camera at whatever materials you would like to share
  • This is where you will have to position what you want to share to get the best view – but you will see ‘how you are doing’ in the main Zoom session.
