Technical Discussion January 27 2009

SFU Burnaby 1:30pm - 2:20pm

Warm Up Topic

What is your favourite graphical effect/technique/style seen in games?

Topic 1: Demonstration of Nintendo DS Homebrew software using wlan-waves

"sniff_jazzbox creates an audible city. it converts the wlan-waves into sound waves. the wlan conversion uses a streamsearch algorithm which was also used in streamfishing and searchsongs." —

"wardive is an adaptive game with locative levels. it converts wlan-waves into game objects. the wlan conversion uses a streamsearch algorithm which was also used in streamfishing and searchsongs." —

Topic 2: Interactive hardware

Gaming is becoming more interactive with gaming platforms using microphones, touch screens, accelerometers, gyroscopes, and video cameras to name some. Like those applications mentioned in topic 1, people are starting to explore this form of interaction more.

  • April read somewhere that a camera was placed in a subway station that would analyze how fast people were moving and change the music accordingly.
  • Johnny Chuch Lee's projects come to mind such as head tracking.
  • Blurs reality and is ultimately a quest for virtual reality similar to The Matrix or Holodecks in Star Trek.
  • Eric Raue says games are becoming more reality aware.
  • These days laptops have accelerometers built in to prevent hard drive damage when moving the laptop around. Could be used for games.

Topic 3: Designing a reality aware game

Karol posed a question of what type of game we could make with all these hardware components. The game would most likely be portable because you would be able to interact with the world instead of one room.

Initial hardware suggestions

  • accelerometers
  • video recognition
  • microphone
  • GPS
  • wifi

Perfect candidates are the Nintendo DSi or iPhone.

Idea 1: Educational tool for viewing stars

  • Capture a picture of the stars and find constellations
  • GPS only gives you position, not direction so take a picture of the north star and use it as a frame of reference.
  • Make your own constellations after taking a picture and have other people look for them.
  • Perhaps build the playing field of a game out of the stars visible.
  • The real technical challenges would be image processing and not being able to see stars well in the city.

Idea 2: Picture scavenger hunt

  • Take pictures of locations and store the GPS location as well.
  • The pictures must be shooting something that is findable from over 10 meters away (ie. no close up of a wall)
  • Score points based on how difficult your picture is to find by how many people went near it but did not find it.
  • Score can decrease as more people find it.
  • Drawing shapes or revealing hidden pictures in negative space could be interesting
