The Hidden Village - Postmortem
The thoughts and opinions expressed are those of the writer and not Gamasutra or its parent company.
The Hidden Village is an educational game that teaches students geometry through motion capture technology. Various characters in the game prompt the player to imitate a series of poses on screen, each pose followed by a multiple choice geometry question related to the motions performed. The project is a collaboration between researchers from the University of Wisconsin and Southern Methodist University (SMU), aiming to improve the math-learning experience for children in today's shifting educational landscape.
Development on The Hidden Village began in 2015 on the now-defunct Extreme Reality motion capture SDK. With this technological foundation in place, SMU Guildhall students Katie Wood and Leo David provided narrative and artwork, respectively, to ground and improve the player experience. I joined the project as the game's producer from May 23 to July 14, 2016 as part of a Directed Focus Study course at the Guildhall. During my time on the project, I worked with a student programmer John Wilson to port the game from the Extreme Reality SDK to the Unity engine, with the Microsoft Kinect as the game's new motion capture platform.
The process was new and exciting for both Wilson and I, and we learned many valuable lessons in this short amount of time.
What Went Well
University bureaucracy was a blessing in disguise.
Unlike the beginnings of typical game dev projects, where teams are abuzz in a flurry of brainstorming and prototyping, we had to conquer a mountain of paperwork first. To complicate matters, The Hidden Village project is a collaboration between, for all intents and purposes, three universities: the University of Wisconsin, SMU main campus in Dallas, and SMU Guildhall in Plano. In addition to nailing down deliverable expectations from my stakeholders, getting my programming intern on Wisconsin's payroll, and getting up to speed on the game's current state, we had to wait about two weeks to receive the Kinect hardware essential to our development, thanks to a multi-step ordering and approval process.
For anyone familiar with the rapid pace of Guildhall projects, finding yourself in a holding pattern can be an extremely frustrating experience. But it forced me to get smart about how to best use the team's time while we waited, to think about what the project needed beyond simply the product we were working on. And that gap, like many projects, proved to be clear documentation. So I set out to create a library of documents that could help future developers once I left the project: a Technical Design Document (TDD), Asset Database (ADB), Asset & Development Plan (ADP), a Trello board for bug-tracking, and a Google Drive account for file sharing between the various universities, among other things. Meanwhile, I had the team's programmer alternate between reading through as much of the existing code as possible and building a database of resources and tutorials for developing Kinect software (neither of us had prior experience with it).
The results were fantastic. After learning the ins and outs of the Kinect, our programmer was able to hit the ground running once our hardware finally arrived, and he was able to complete a full port of the existing game in only a month. At the time of this writing, the project is about three and a half months ahead of our stakeholder's expectations, and we now have an extensive body of documents to help future teams as The Hidden Village enters further stages of development.

Happenstance provided the perfect usability test group.
The Hidden Village is targeted towards middle school students, and just so happened that our development phase coincided with the Guildhall Academy, a summer camp for middle and high schoolers. Not only did these students fit our target age range, but as aspiring developers themselves, they were very eager to participate and do their part to help improve the game.
The playtest revealed a major design flaw that the team had predicted but had no means to confirm previously: players come in all shapes and sizes, and the Kinect needs to be ready to adapt to that. With only one programmer on the project, the Kinect only had one body type as a reference, and as a result, the game was almost unplayable for several of our testers.
Halfway through our testing group, realizing our usability data was not very valuable given the circumstance, I decided to pivot and have the remainder of the testers help train the Kinect to detect a larger variety of body types. The students were very happy to play their part in helping improve the game, and we were able to begin the foundation for training a better, smarter Kinect. Everybody wins!
What Went Wrong
Underclarification of progress resulted in a missed milestone.
The Hidden Village is my first game in which I interfaced with a stakeholder outside of SMU Guildhall: Dr. Candace Walkington of the School of Education at SMU main campus. She provided me with a list of deliverable expectations for my time on the project and beyond, which served as the basis of my milestone planning strategy. My overarching objective for July 14, 2016 was to rebuild the entire game in the Unity engine and replacing the old motion capture technology with the Kinect, with a subgoal of getting a basic build running before the Guildhall Academy concluded on July 1.
Although I maintain regular email contact with Dr. Walkington every week, I made the fatal mistake of not clarifying with her that our definitions of "playtest ready" were the same. The day before the playtest, she emailed me asking about a piece of content that didn't make it into the previous build of the game, which I hadn't planned to integrate until the next milestone. Without it, she told us, the playtest would not reveal any valuable research data for her. After a mild panic attack and a flurry of emails back and forth, we decided to cancel the playtest until we could create a build of the game that would yield research data for her and usability data for us.
Fortunately, our testers were so eager to try the game that many of them came back to the Guildhall for our playtest two weeks later, but this setback could have been avoided through better communication. I didn't ask my stakeholder enough questions, and I didn't ask my programmer the right questions about our progress.
What We Learned
My biggest takeaway from working on The Hidden Village is the importance of clear, intentional communication so that all parties in the game-making process are on the same page. This is something our professors at Guildhall drill into us for our large team game projects, but this was the first time it applied to a "real-world" scenario, as we worked with an outside stakeholder with real money and an academic reputation on the line. Fortunately, the worst ramification of our missed milestone was inconveniencing our usability testers, but a missed milestone is still a missed milestone.
Another obvious takeaway: investing time at the beginning of a project in careful planning and research really does pay off in the long run, especially when working with "new" or experimental technology. If our programmer dove straight into building our Kinect version of The Hidden Village without a comprehensive knowledge of what that process entailed, his development experience would have likely been much more touch-and-go. Instead, he became a relative expert after dozens of hours watching tutorials and reading through documentation, and he built an extensive database of resources to fall back on in case he ever ran into issues during development.
Lastly, my experience on this project reinforced the importance of embracing the Agile software development philosophy. Our lack of hardware at the start of the project forced the team to pivot and focus hard on planning and research, resulting in an incredibly smooth development process and blazing past our stakeholder's deliverable expectations. Later in the project, the revelation of the Kinect's limitations that emerged in the middle of usability tests prompted another pivot, this time utilizing our testers to actively improve our core technology. At this point in my short career as a producer, I've come to welcome setbacks and hardships, because they force me and my teams to come up with creative solutions to improving our processes, and ultimately our end products are all the better for that.
