==Motivations==
 
 
We want to "make the invisible visible", to bridge our senses.  Many group members were inspired years ago by this [http://www.wired.com/wired/archive/15.04/esp.html awesome Wired article], which describes obtaining an <i>unerring sense of direction</i> 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?

"Sensor" is the device that detects external stuff that the body (probably) can't detect.  Sensors can be divided into those that sense the world, and those that digitize a user's actionsThe latter are more commonly called "human input devices", (HID's).

"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.

==Sensors (Input to the body)==
  
"Armature" is the physical component of the device: the belt, hat, armband, etc; distinct from the electronics.
+
Our first task will be to experiement with data input modes. What signals can we overlay upon the body's standard senses, and by what means? Of particular interest are electro- and vibro-tactile stimulation. What bandwiths are available according to the nature and location of input stimuli?
  
==Mailing List==
+
Secondly, we need to identify useful measurements to input. Sensory augmentation has been around for centuries, think of magnifying glasses or hearing aids. Sensory substitution, on the other hand, involves the transposition of one sensory stimulus into another: seeing sound, hearing distance, feeling vision, etc. Sensory extension is measuring signals beyond regular human abilities, such as magnetometry, radar, echo location or even digital signals coming from a wireless network carrying such diverse information as locations of friends in crowds or network activity on one's website.
  
We have created a [https://www.noisebridge.net/mailman/listinfo/cyborg cyborg mailing list] on the Noisebridge server.  Please join us!

==Brain/Body Output==
  
[[Pulse Necklace]]

The study of output is a question in how we can interface with machines beyond the manual button pushing and lever pulling. Some ideas in this field are biomechanical feedback, pulse detection, eye-tracking, etc.

[[UltraSonicHearing|Ultrasonic Hearing / Echolocation]]

There seems to be a strong interest in developing a tactile wearable compasses, but in ways far more effective and practical than big vibrating belts. A first study will be in what other possible device configurations and what possible signal modulation are both 1) intuitive enough for sub-concious integration into the wearer's cognitive space, and 2) pratical to wear in terms of size, weight, design, energy consumption, and noisiness.
  
[[TechnicolorDreamcoat|Technicolor Dreamcoat]]

Another field of general interest are tongue stimulation devices. We will discuss how to either order or make one or several of these.
  
 +
==Interesting questions==
 +
What new sense do you want?  What existing sense might it map onto?
  
 
+
The brain seems to integrate consistent input quite easily. What happens after this integration has happened, when the input stops (i.e., you take off the belt after wearing it for days)?
