1. NerdHerder is a motion-controlled augmented reality puzzle game developed by the Augmented Reality Game Studio at Georgia Tech. 2. The game uses augmented reality to place digital characters called "nerds" on a real-world table that players can then herd around using motions and gestures detected by the device's camera. 3. Developing the game presented challenges related to camera control, new control mechanisms, tutorial design, and deployment to different devices and markets. Frequent playtesting and iterations were used to address these challenges.

Notes de l'éditeur
- Hello everyone. I’m Yan. I’m Sam. We are from Georgia Institute of Technology. Today, we are very happy to be here and present you our mobile Augmented Reality game, NerdHerder. NerdHerder is a collaborative project in the Augmented Reality Game Studio at Georgia Tech, Savannah College of Art and Design, and Berklee College of Music. It is also having different purposes, such as how to create a student project that can be downloadable and playable to the public; research purpose of understanding player behaviors.
- NerdHerder is a motion-puzzle game for causal mobile game players. Here is the trailer 1. A player print out the game board, point their camera at the phone, and they can see the game world comes out of the piece of paper. 2. Your goal is to herd the nerds back to their office 3. The management tools you are going to use are donuts, paperwork and techie toys. And you dangle them in front of the nerds with a fishing rod to attract and repel the nerds 4. There are distractions and challenges along the way of going to nerds office, such as moving bosses, coffee boys, sports posters, conveyor belts etc. Demo or Video
- As you may tell, we were inspired by many icons of pop culture, and our own experience of working in front of computers for many hours everyday.
- More importantly, this game is about herding nerds on your table. With augmented reality interface, the nerds and the office appear on top of a piece of paper and players physical movements make a difference in the game. This leads to the core design question we try to answer: how do we make the best of novel interfaces, in this case, mobile Augmented reality interface, to shape enjoyable and novel player experience?
- there are a lot of definitions of augmented reality out there.
- Augmenting the environment
- Augmenting the user
- Augmenting the objects
- The markers are recognized when they are in the view Shows the objects alive on the cards
- Point and shoot game; 2009
- We also design NerdHerder to make the best of mobile augmented reality interface. There are many definitions of augmented reality out there. In particular, we focus on the type of AR that tightly registers graphics on real world objects.
- We did not try to answer this question alone. We are all involved in the AR game studio@Gatech, where students with technical, artistic, and musical talents come together and create fun game mechanics that leverage the affordances and constraints of AR.
- One precursor project for NerdHerder is NerdFerno, a sandbox for experimenting with various interactive tools to mess with the nerds. In the playtesting, we saw that people loved scaring the nerds by sneaking close to them physically and scare them. There is something that is special about players feel they exist in the same space as the nerds, and the physical movement makes this feeling of being present more believable.
- We decide to focus on this piece fun experience, and bring it further to a real game. That’s when we started to make NerdHerder, the core game mechanic was to push nerds away from the camera. It make sense because the nerds in our game try to avoid eye contact with people. But this interaction is not precise, players tend to overshoot the nerds, and it is a game interface that is “easy to learn, impossible to master.” We went through several major iterations to address the usability and playability issues of the core game mechanic.
- In NerdHerder, we focus on augment gameplay experience with players’ bodily presence and physical movement. More than viewing the game from a perspective they can control, players interact with the game in a flowy and responsive way.
- <Video>
- Eventually, we come up with the fishing rod interface. Players see a fishing rod sticking out from their camera phone, and they can dangle donuts or paperwork to attract and repel the nerds. It is inspired by a kids toy “Let’s Go Fishin’” that requires motor control, dexterity and steady hands. We are happy about this game control from playtesting. Players get the idea almost immediately when they see the fishing rod. It also provides constant presence and contious feedback that are highly responsive to players’ physical movements.
- Creatively blending first person and third person presence
- This game mechanic is integrated with the puzzle solving challenges and tutorial design in the game. Sam is going to walk you through this and talk about our design thinking during the demo.
- AR provides different kinds of camera control: window to the world. Mobile AR is especially different because it is held in the hands of the players. We are not completely unfamiliar with this kind of control, In other games, we have conventions
- Frequent and early playtesting is the method that we rely on for iterations of the design.
- Buzz playing We designed for a tutorial
- Do we need a demo here?
- Then, another group of students came in, and made a game based off that one single mechanic of proximity based interaction, and made a game of it.
- The current version of NerdHerder has a completely different game mechanic. We started with the pushing mechanic inherited from the pervious game. In the playtesting, we soon found that it has two problems, lack of feedbacks and difficult to control the nerds’ movements. Then we tried to add push and pull mechanic ->Teleported boss; eventually we decide to strap things We followed the fast iteration loop to make design decisions
