A review of project status:
Must have 5 channels:map 5 output channels
Power consideration
Should have the feel and robust enough for testing
Small package-> looks like a cell phone,
We try to make as many as possible
Speaker port protocol- ask Jim Youll?
Targeting general user market... and deaf-blind

Next meeting-->We will be meeting on Monday, April 9th.
Next meeting agenda-->Prototype assessment- A pair of 5 channel i/o devices
                                        CHI Touch comparison of notes and experiences

Concern about language design and content of language
Can people make interpretation easily?
Emotions are not discrete, symbolic language may be discrete
There is no ready made, obvious high-level lanugauge for 5 fingers
If you care about input speed, then make a new language
If you care about ease of use, then use existing languages

Morse code- signal transmission-- the importance of duration and gaps
Started out by learning letters
individuals letters then became hard to distinguish
they were recognizing whole sentences and mulitiplexing
also doing simultaneous translation
-->Comtouch offers 5 channels instead of just one

COMTOUCH advantages  (A short summary)
0.New Possible use Broadcasting Tactile Sign Language- brought up by Sile
1. SKILL TRANSFER-->Transfer of knowledge of experience because encoding and decoding is at same place
2. Simultaneous translation (fail- the use of localized spatial i/o arrangement might foil this)
3. The transition to emotional vs. language content can be distinguished by usage pattern.
4. A low bandwidth signal that can allow some simulatneous translation.

0.New Possible use Broadcasting Tactile Sign Language- brought up by Sile
-for the deaf-blind
-everyone can listen
-collaboration and participation
Hyptothesis: A tactile broadcasting can be achieved
Test: Have a broadcast session wit the COMTOUCH

Localization on input and output space allows better communication
Dividing the center of attenion at different parts of body spatially might be hard to attend to.
Distinguishing in and out might be hard if the i/o space is overlapping.-->Handjive Tug of war?
Separation of i/o space a little bit may or may not be good
Given that:  The Input Space is equal to Output space here
Hypothesis: The transfer of knowledge is quicker, as in TUI.
Test: If one subject inputs via the screen, can they receive input correctly?
Testing inputting only, and local tactile feedback helps learning

Hypothesis: If I can record, make a transcript identify transition from emotional to linguistic prove change of mode from emotion to discrete
use pattern of language from simultaneous to more patterned tranmission.

Test: Roz Picard suggested an affective test of effectiveness:
    1.Observe language and use
        -counting occurances of emotional lanugage
        -tasks with emotional component
    2.Record language and transcribe
    3.Analzye motion (Continuos vs. discrete) identify
    4.See if the content coincides with usage

Separate skill vs. attention dividing skill.
Hypothesis: We can do some simulatneous transmission because of the low bandwidth of attention needed by the device
Test: See if someone can simulatneous send and receive signals at the same time

Scheduling
Sile will be away for CHI, and also on April 16th to Ireland.
Nat Durlach will be visiting the Lab on April 25th, Sile has invited him to join.
Hong Tan will be talking here on May 3rd, perhaps we can ask her to join

CONCLUSION
Next meeting-->We will be meeting on Monday, April 9th.
Next meeting agenda -->Prototype assessment- A pair of 5 channel i/o devices
