Recognizing what technologies will be useful prior to prototyping is error prone, with resulting higher-than-acceptable developmental rejection rates. MIT Lincoln Laboratory (MIT LL) has been using serious games to aid in technology assessment programs. This approach combines economic game theory with rapid-play, rapidly-developed digital simulations to collect quantitative data, improve qualitative feedback, and crowdsource the ingenuity of human experts.

Serious Games for Technology Exploration A game is a sensor for measuring human decision making. Serious games are a tool for system analysis to addresses the role of human decision, failings, and creativity. Technology exploration games crowdsource discovery of new tactics, clever combinations of technologies, and requirements estimates based on iterative experiential play.

HIVELET Approach Combine Game Theory with Rapid-Play Digital Simulations Human-Interactive Virtual Exploration for Lightweight Evaluation of Technologies • Rapid-Play Digital Simulations (‘Games’) – provide concrete intuition about potential benefit – many iterations allow for more exploration and data collection • Game Theory / Auction Theory – player must think critically about what is most beneficial – player can choose custom combinations to execute a novel strategy rapidly alternate between modes to build intuition, collect data, and explore novel tactics Player-Driven Capability Selection Mission Simulation as Digital Game HIVELET Connections - 10 Rob Seater 2017

Case Study: UAV Integration into Infantry Squads 10 minutes per full cycle Mission: find downed predator drone in urban environment, retrieve data, destroy predator, extract safely Capabilities: personal UAV sensors, control/flight systems, battery, targeting support, intelligent behaviors Research Question: Which capabilities or combinations of capabilities are most valuable to this mission, and how do they alter tactics and doctrine?

Experimental Trials • 36 participants over 5 trials – 25 lab researchers – 9 military fellows – 3 admin/support • 2.5 hour play session – 1:00 Training – 1:00 Score competition – 0:30 Discussion • Quantitative & qualitative results – Positive feedback from experienced military fellows & lab UAV researchers – Data and discussion supported the primary experimental questions – Written report in progress Goal: Demonstrate the value of data collected by this technique, not the realism of the technologies modeled or environment used for that validation.

Example HIVELET Output Quantitative Qualitative Anticipated pre-game Not anticipated Strategy used in game Strategy not used in game Player technology selection preferences. Player preferences correlate with performance and change after gameplay. Strategy Effectiveness Unanticipated, effective strategies High Moderate Ineffective Unobserved Also Also • Changes in technology utility perception • Player perception of risk tolerance vs. scoring features • Player rationale for observed strategy evolution • Consequence by architecture • Information required for player to take action • Player performance relative to benchmarks HIVELET Connections - 15 Rob Seater 2017
Key Questions for Method Validation • Convergence. Do players quickly form and express consistent opinions? • Accuracy. Are player opinions worth listening to? Does it match success? • Transferability. Do lessons in the game map to the real world? (e.g. risk) • User Impact. Does this approach affect the opinions players express? • Novel Lessons. Do we learn anything new, or just confirm prior knowledge? HIVELET Connections - 16 Rob Seater 2017
Experimental Results • Convergence – Do players learn the game and technologies quickly? – Does the game change their opinions? – Was 1-2 hours enough play time? Image Source: LL Graphic HIVELET Connections - 17 Rob Seater 2017 Lesson: We can collect consistent data in a short time.
Experimental Results • Accuracy / Consistency – Does player make good choices for themselves? – Can we trust their selections to reflect utility? Image Source: LL Graphic HIVELET Connections - 18 Rob Seater 2017 Lesson: Players make good choices for themselves.
Experimental Results • Score Sensitivity / Realism – Should we believe that behaviors in the game match behaviors in the world? – Will players be appropriately risk averse in a virtual environment? – Can we control their level of risk taking? Averages from Post-Game Survey (1 = low, 5 = high) Image Source: LL Graphic HIVELET Connections - 19 Rob Seater 2017 Lesson: We can control player risk aversion with scoring.
Experimental Results • Improve the Quality of Qualitative Feedback – Does playing a game change player opinions and ability to discuss the topic? – Does making in-game choices about capability selection change opinions? Image Source: LL Graphic Lesson: Customizing loadouts make players more critical than just experiencing the virtual model. HIVELET Connections - 20 Rob Seater 2017
Experimental Results • Crowdsourcing Ingenuity – Do players discover novel strategies? – Do players discover surprises in the value (or lack of value) of technologies? Image Source: LL Graphic HIVELET Connections - 21 Rob Seater 2017 Lesson: Players discovered novel (effective) strategies.
Lessons Learnt for Rapid-Play Games • Design – Design the game around the data to be collected (sensor vs. simulation) – Focus on key decisions, abstract away detail when possible – Balance experimental design with realistic models (are rare events rare?) • Feedback – Use multiple scoring axes or variable scoring weights – Clarify best outcome vs. best practice • Scenarios – Procedurally generate scenarios (faster, more insight) – Use a ‘detective’ style game when possible (cleaner analysis) – Use turn-based games when possible (clearer intent) • Complementary Techniques – Precede with open ended tabletops to discover relevant info & actions – Follow with more traditional detailed / immersive evaluations HIVELET Connections - 22 Rob Seater 2017
