problem how can activity zones be used to aid lighting design
Problem: How can activity zones be used to aid lighting design?
  • System can learn:
    • Where people are over time (Activity Zones)
    • What areas are lit over time (Lighting Zones)
  • System can then:
    • Communicate the motion of a play
    • Test lighting design ideas
    • Communicate details of lighting design
    • Control lighting systems
    • Teach people about production
existing activity zone system
Existing Activity Zone System
  • Working system implemented in CSAIL as part of Project Oxygen
    • People tracked by camera or generate simulated data
    • Infer zones by observing behavior over time
    • Allow users to relate zones to actions or context features
building upon existing system
Building Upon Existing System
  • 3 Necessary Components
    • Location Awareness – What zones do people inhabit?

What areas are lit?

    • Script (Time) Awareness – Where in the script is the action taking place?
    • Agent using context information to process and act upon information in a way useful to designers
step 1 location awareness tracking to zones
Step 1:Location Awareness: Tracking to Zones
  • Problems:
    • Resolving zones from tracking data: Current algorithms create many small zones where one large one would be desirable when presented with small tracking data set.
    • Need second set of lighting zones
  • Solution:
    • Merge zones by defining activities zones in

relation to where people are for sections of

the script (scenes, between cues). Combine

all zones that exist during one section into a

larger zone

    • Input lighting zones as either complete zone
    • or lighting source and beam information.
step 2 script awareness
Step 2:Script Awareness
  • Script Awareness enables a better interpretation of the actions taking place
    • Meaning of an action comes from the context surrounding that action
    • In a play, that context comes from the script
  • Create a “super” script allowing a connection to be made between movement and text
    • Maintain audio and text copes of script
    • Relates movement to appropriate point in script
step 3 the agent using gathered information
Step 3:The Agent: Using gathered information
  • Create an Agent to combine data and aid designers through:
    • Playback: Show lighting designers how stage is used
    • Integration: Determine if people are always lit (all activity zones are contained by lighting zones)
    • Communication: Convey design ideas: show changes in lighting zones as the play progresses over time.
    • Control: If an actor accidentally steps into an unlit area, turn on the light best situated to illuminate him.
resources dependencies
Resources & Dependencies
  • Working with Kimberle Koile in collaboration with Royal Shakespeare Company
  • Building upon current Project Oxygen Activity Zone system
  • Need a method of collecting rehearsal or performance tracking information
    • Simulate data (Exists to simulate single person)
    • Use existing Project Oxygen activity zones setup room and record data while performing
short term plan
Short Term Plan
  • Further meetings with Kimberle Koile
  • Learn existing Activity Zone system
  • Take 6.871 – Knowledge Base Systems
  • UROP in Spring
  • Begin Thesis
where can this idea go
Where can this idea go?
  • 3D rendering of dynamic lighting design
  • Expanding to aid other theatrical areas:
    • Technical Direction
    • Costume Design
    • Adapting touring shows to new spaces
conclusion
Conclusion
  • Activity zones and context aware computing can be used to aid lighting design
  • Expanding activity zone system to use both lighting and activity zones
  • Creating an agent which can use this zone information to aid in the development, testing, communication and realization of a lighting design.
