Interactive Theatre Designer

Interactive Theatre Designer

This skill provides guidance for creating theatrical experiences where audiences participate in, influence, or co-create the performance through interactive systems and branching narratives.

Core Competencies

• Branching Narrative: Multi-path story structures
• Audience Agency: Meaningful choice and participation
• Immersive Design: Environmental storytelling, site-specific work
• Live Systems: Real-time adaptation and emergence
• Hybrid Formats: Physical/digital integration

Choice Architecture

class NarrativeChoice:
    """A decision point in the story"""

    def __init__(self, prompt, options):
        self.prompt = prompt
        self.options = options
        self.context_requirements = []
        self.consequences = {}

    def evaluate_options(self, audience_state):
        """Determine available choices based on state"""
        available = []
        for option in self.options:
            if option.is_available(audience_state):
                available.append(option)

        # Always ensure at least two meaningful options
        if len(available) < 2:
            available.append(self._create_fallback_option())

        return available


class StoryBeat:
    """A unit of narrative action"""

    def __init__(self, content, duration_range, choice=None):
        self.content = content
        self.min_duration = duration_range[0]
        self.max_duration = duration_range[1]
        self.choice = choice  # Optional NarrativeChoice
        self.state_changes = {}  # What this beat modifies
        self.prerequisites = []  # What must be true to reach this

Consequence Systems

class ConsequenceTracker:
    """Track choices and their ripple effects"""

    def __init__(self):
        self.choices_made = []
        self.world_state = {}
        self.character_relationships = {}
        self.available_endings = set()

    def record_choice(self, choice_id, option_selected, timestamp):
        self.choices_made.append({
            'choice': choice_id,
            'selected': option_selected,
            'time': timestamp
        })
        self._apply_consequences(choice_id, option_selected)
        self._update_available_endings()

    def _apply_consequences(self, choice_id, option):
        """Apply immediate and delayed consequences"""

    def get_story_fingerprint(self):
        """Unique identifier for this audience's journey"""
        return hash(tuple(
            (c['choice'], c['selected'])
            for c in self.choices_made
        ))

Audience Agency Design

Choice Design Principles

Make Choices Meaningful:

• Clear stakes: What's at risk?
• Visible consequences: Changes they can observe
• Emotional investment: Characters they care about
• No "right" answer: Multiple valid paths

Avoid Choice Paralysis:

• Limit to 2-4 options at decision points
• Provide adequate context (but not too much)
• Use time pressure sparingly and purposefully
• Signal importance level of choices

Voting and Collective Choice

class CollectiveDecision:
    """Aggregate audience input into story decisions"""

    def __init__(self, voting_method='plurality'):
        self.voting_method = voting_method
        self.votes = {}

    def collect_votes(self, options, timeout_seconds=30):
        """Gather votes from audience"""
        # Methods: raise hands, mobile app, physical movement, sound
        pass

    def resolve(self):
        """Determine outcome based on voting method"""
        methods = {
            'plurality': self._plurality,      # Most votes wins
            'supermajority': self._supermajority,  # Needs 2/3
            'consensus': self._consensus,      # Unanimous
            'weighted': self._weighted,        # Some votes count more
            'random_delegate': self._delegate  # One person decides
        }
        return methods[self.voting_method]()

    def _plurality(self):
        return max(self.votes.keys(), key=lambda x: self.votes[x])

Best Practices

Designing for Failure

• Plan for empty rooms (no one chooses that path)
• Plan for crowded rooms (everyone chooses same path)
• Plan for confused audiences (unclear instructions)
• Plan for disruptive participants (graceful management)
• Plan for technical failures (degraded mode operation)

Rehearsal Process

1. Paper prototype: Walk through on paper first
2. Block rehearsal: Test spacing and movement
3. Branch rehearsals: Practice each path separately
4. Integration: Run full show with choices
5. Audience tests: Invited audience for feedback
6. Tech: Add all technical elements
7. Previews: Public performances for refinement
