We have created an asymmetrical multiplayer game, using light interaction via the Pixelsense to create an immersive and cooperative game. One of the players uses a flashlight to shine on the Pixelsense. This will illuminate the virtual world the other player is in.

We used Unity for game programming and integrating the peripherals. Maya, Blender and Photoshop were used for creating models and artwork. One player gets to use the HTC Vive to explore and interact with the world in VR, whereas the Pixelsense player can only observe the world through the screen. The Samsung Sur40 Pixelsense is a display that has sensors measuring IR light to enable touch based interactions and object recognition. We have instead implemented our own feature, based on C# and C++, which allows interaction using light. The screen detects the light and it is mapped to the virtual environment. As far as we know, this is a new use for the Pixelsense, something that has not been done before.

To encourage interaction and communication between players we have implemented several elements into the game. The first part of the game is explaining the different perspectives and equipment that both players have in the arsenal. Since the Pixelsense player is stuck in a bunker it is evident that the player needs to see the world on a screen. It also provides an incentive to cooperate with the VR player since they cannot escape the island by themselves. The second part deals with both players having different views. For example, the Pixelsense player has an overhead view of the virtual world. From that viewpoint they can observe and guide the VR player, but cannot see inside a house and beyond terrain. The Pixelsense player also has access to clues about what to do or find to progress, whereas the VR player find clues to complement the other player’s information.

A way to take this project further would be to study how people communicate when different information is presented to different players. How do people cooperate when they are presented with conflicting information? Will they work together or against each other? These are some of the questions that could be examined through observational studies. Answering these questions would give insight to how people interact in a multiplayer game in both the real world and VR.

To summarize, we present a new way to interact with the Pixelsense. The multi-platform game enables deeper social interaction between people by presenting separate pieces of information to different players. It is also a fantastic game by itself, we hope you get to play it.
