Sensebridge: The Noisebridge Cyborg Group

"If you can't beat the robot armies, join them."

We are concerned with human-machine interfaces.

Motivations

We want to "make the invisible visible", to bridge our senses. Many group members were inspired years ago by this awesome Wired article, which describes obtaining an unerring sense of direction via a compass belt. Is the brain really plastic enough to adapt to entirely new senses? How natural would it feel after you've fully adapted? Then what happens when you take the device off?

What new sense do you want? What existing sense might it map onto?

Terminology

To avoid confusion (where possible) we'll try to use these terms.

"Sensor" is the device that detects external stuff that the body (probably) can't detect. "Display" is the way the device shows data to the body (not necessarily visually). This gets around the device-centric / body-centric problem that shows up when using the terms input & output. "Armature" is the physical component of the device: the belt, hat, armband, etc; distinct from the electronics.

Mailing List

We have created a cyborg mailing list on the Noisebridge server. Please join us!

Component Sourcing

Here are pages for discussing:

sensors

detect a property of the world

displays

communicate it to the body/mind

armatures

hold the above together and in the proper place on the body

They also include a list of all known/speculated types of each.

Sensor and Display API

  • What might that mean?
    • A standard protocol that can:
      1. encompass most sensory data of the sort we are interested in researching
      2. allow for presentation of any those data through any of a wide variety of modalities
  • Why?
    • Plug-and-play(ish) interoperability of sensors and input modes. Build three sensors and three input modes, and we have 9 possible combinations, und so weiter.
    • Simplify development by separating sensing and presentation design/tasks.
  • How?
    • On the data sensing end:
      1. Identify a primary set of interesting stimuli, consider various encodings thereof.
      2. Abstract away from the physical phenomena the stimuli represent and look instead at common patterns in the data streams.
      3. ???
    • On the data presentation end:
      1. Identify and prototype a number of input methods.
      2. For each method think of:
        • What modulations of the signal are possible; intensity, spacing, direction, timing...? Based on that, what is the theoretical bandwidth of that input method?
        • How sensitive is the average person there? How much of the signal can the brain interpret meaningfully (too much noise vs. too weak of a signal)? Based on that, what is the practical bandwidth that we might expect?
