In-Depth Activity Comments
The research and design issues for each of the interfaces you choose to examine playing a game you or other person you know plays a lot are likely to be different but some may overlap. For example, a game like Fortnite when played outdoors using mixed reality could entail a group of people playing together as a team, trying to avoid hidden augmented reality obstacles in the physical environment. The game could use ultrasonics, GPS or Bluetooth to track the human players in relation to the virtual objects overlaid in the physical world. Each player would don a wearable jacket or tunic that was embedded with sensors and LEDs (that could light up depending on whether they hit an obstacle or were fired at).
The tunics would need to be easy to put on over existing clothing and remove without requiring too many parts to be attached together. Another concern would be how do the players know when they have scored points or who is left in the game - what kinds of real-time feedback would be appropriate? As well as considering the use of LEDs to show immediate 'hits' how might vibrotactile feedback be used to let others know what each is doing? How will the players understand their role in the game if it is designed as a collaborative game? What rules would you include? How would you enable the players to communicate with one another?
Compared to a single user game, on a PC or smartphone, there is a lot of potential of this kind of first person, role-playing physically embedded simulation for facilitating new forms of learning and reflection in a group setting plus engendering much fun.
