Lazor Lab is a cross-technology multiplayer game experience made specifically for large environments ("play space") with installed tracking system and floor projection. The players are detected by a tracking system and control their avatars by moving in the space. Additionally smartphones and their sensors are used to perform actions in the game and to control the orientation of the avatars. Lazor Lab features two game modes, Lazor Arena and Lazor Lab.

Lazor Lab and Lazor Arena had their live premiere during the Ars Electronica Festivals 2015, as the DeepSpace multimedia room in the Ars Electronica Center in Linz was the original environment the application was made for.

MoCo Motion

MoCo Motion is a framework to integrate so called smart devices (smartphones, tablets, etc.) into floor-based co-located games. It extends the players' interface to the system in order to extend the play dynamics. The main benefits of MoCo Motion are explicit user actions and personalized feedback: Users can trigger actions in the application in multiple diverse ways (physical and virtual buttons as well as sensor input). Also they receive individual feedback from the system (smartphone speakers and vibration motor).

Moco Features


MoCo Motion is the associated project to the master's thesis of Andreas Friedl. It was developed in cooperation with the research institute PIE. In the following publications about co-located games are listed which either were a direct result of the work on MoCo Motion or affected the project significantly:

Game Modes

Lazor Arena

Lazor Arena is a competitive battle arena where players collect energy and release it onto their opponents to score points.

Each player has a virtual pointer which is tied to the smartphone's orientation. This way the players can aim freely in 360° while shooting laser beams or definding with their shields. The smartphone is also used to provide audio and vibration feedback when the player gets hit by laser beam, blocks a beam with the shield, collects a new energy block and so on. Once the game timer expires a score table is presented and the winner is declared.

Lazor Lab

Lazor Lab is a collaborative game where players have to defend their base from incoming enemies. Hostile polygons will break through the surrounding wall and attack the core of the base. The players have to manage resources, repair the wall, and power the mighty stationary laser guns. The game has a clear focus on communication, collaboration and resource management.

The controls in Lazor Lab work similar to Lazor Arena. However, the players can hand over energy blocks to other players. This is sometimes required as only a player with three energy blocks of matching colors can repair a broken wall. From time to time a big enemy protected by a shield will enter the field. It can only be destroyed with the sentry laser gun which requires three energy types of different colors. The players win the game if they manage to defind the core in the center of the field for six minutes.
