Lighting Design aided by Activity Zones and Context-Aware Computing
Andy PerelsonAdvisor: Kimberle Koile
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
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
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
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
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
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
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
Further meetings with Kimberle KoileLearn existing Activity Zone systemTake 6.871 – Knowledge Base SystemsUROP in SpringBegin Thesis
Where can this idea go?
3D rendering of dynamic lighting designExpanding to aid other theatrical areas:
Technical Direction Costume Design Adapting touring shows to new spaces
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.
