Who Uses Truphone & Why?
5
•  What do you do if you have two sites in two different countries and you work in
both, or perhaps you manage people in both?
•  With one phone you are home in more than one country.
•  You have multiple numbers on your phone.

•  Shannon’s law:- Communication is like entropy –
The equation shows the symbolic capacity of a
channel in the presence of noise.
•  Polymath
•  Invented the analogue computer
•  Did the original mathematics of chess
•  Proved the one-time pad (a type of code) is
unbreakable.
•  Strange consequence that crosswords can exist
in the English language. Linguistic: S/N = 2+.
•  Did he start our industry?
Claude Shannon
Origins of the Science of Communication

Written language origin Sumer 3000BCE, Mesopotamia - Cuneiform
But it happened much earlier

Hieroglyphics

•  French / Spanish - Phonetic Auditory Languages
•  English - Irregular Visual Language
–  Leicester, sugar
•  Chinese / Japanese Motor Cortex Languages
–  Children learn through repeated writing.
•  We can see this in MRIs and previously with brain
dysfunction.
•  Someone dyslexic people are affected in one
language but may not have the problem in
another.
Good book on this is Proust and the Squid, Maryanne Wolf, MIT.
We co-opt our Brains for Symbolic Language

“That song really spoke to me (man)”, is not
communication.
Although some inanimate objects do
communicate. Light houses for example.
(Don’t crash on this rock.)
With the help of machines
Who is communicating? Usually people!
Are we becoming antisocial animals?

We can recall more than 1000 faces in < 370ms each.
Super recognizers can do every face they ever saw!
We are poor with names. (and symbolic memory in general)
We are usually quite good at telling who works for who. (hierarchy)
We get embarrassed (for example doing a handshake)
We get VERY embarrassed by miscommunicating.
When was the last time you spoke to the wrong person?
We are very political animals (friend / foe - its in a specific part of
your brain that if damaged it gives you imposter syndrome.)
We are very poor at precise communications.
Given we like visual things we are very bad a generating visual things.
We like F2F.
We are poor at paying attention.
Humans are Good and Bad at Things

•  We live in hierarchies
•  We live in families
•  We have strong rules of etiquette around communication
The first thing to realize is we are social animals
People are a bit odd – even me…

Body Language follows the "7%-38%-55%" rule.
Why are we here? We like to face to face.

“Computers don’t have face to face meetings.”
7% words
38% tone of voice – bandwidth in channel
55% body language – video
We have a strong requirement to develop trust
And when you don’t have video and audio you need other means…
Computer v Man (Mechanistic v Emotional)
What’s the difference?

•  iMax, video 7000 by 10000 pixels 100fps. Sound 7 channel. 21bit 100 samples
•  Digital equivalent of reality = video 10000 times greater and audio field. (need
head tracker)
•  Fermi Lab life : one hundred trillion samples per inch of pixelation but this is
only a ‘simple’ quantum view.
•  Maybe super-infinite. (and quantum, highly controversial!)
Can you can never have enough, our bandwidth is huge
Bandwidth of Reality

It’s not just a language thing. Watch the sketch. It’s old fashioned.

•  For non-English speakers. It’s a phonetic trick.
•  X = eggs
•  F = have
Just so you get the joke…
While I get it cued up

•  Question: What would you like for breakfast?
•  Answer: X N M
•  Why is humor there?
•  We use humor a lot to cope with ambiguity (so we can laugh it off)
•  We use it to get people to pay attention.
•  Humor is all pervasive.
•  Computers are not very funny.
In my family because we have seen the sketch the following is a
hilarious joke.
Background Context is Powerful

Here are some computer jokes…
•  Q: What is the difference between leaves and a car?
•  A: One you bake and brush and rake, the other you rush and brake and
bake.
•  Q: What do you call a strange market?
•  A: A bizarre bazaar.
They don’t have the same ‘Qualia’ as us
(intensity of experience)
Computer Humor, Computer Communications

•  How do you get someone to pay
attention?
•  Be there in person!
•  But if not then how?
–  Tell a joke
–  Use bandwidth
–  What…?
•  It affects all sorts of things.
–  Memory
–  Learning of skills
–  Comprehension
Mostly we don’t pay attention…
Lecture Effect, Learning and Memory:- We are a massive filter.
Humans Have Selective Attention

Take a look at the successes. What do they excel in?
•  Discovery (Facebook and LinkedIN are good at this)
–  Social graph (who knows who)
–  Faces (and images and face recognition and tagging)
–  Hierarchy (who works(ed) for who)
–  Background context (Lot of interests and history. Know them before you talk.)
•  What is the hierarchy? (Can you only follow or can you be my friend?)
•  How do you establish permission to communicate?
•  How do you get attention and keep in?
•  Humor – How much of Facebook is humorous video and jokes?
•  Note how little of this of this is in mobile communications…
Bits and Bytes or Body Language & Banter?
So if you are designing a new product, what matters?

In Facebook you can see most of the human factors

Question to Ponder
What is in our communicating brains?

“The question of whether
computers can think is just like the
question of whether submarines
can swim.”
