Lighting Design aided by Activity Zones and Context-Aware Computing

Andy Perelson

Advisor: Kimberle Koile


Problem how can activity zones be used to aid lighting design
Problem: How can activity zones be Computing 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 Computing

  • 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 Computing

  • 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: ComputingLocation 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: ComputingScript 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: ComputingThe 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 Computing

  • 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 Computing

  • 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? Computing

  • 3D rendering of dynamic lighting design

  • Expanding to aid other theatrical areas:

    • Technical Direction

    • Costume Design

    • Adapting touring shows to new spaces


Conclusion
Conclusion Computing

  • 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.
