Where we

re coming from (1994 and earlier
)


1988
-
93 wireless, pen, and speech infancy


1994
-
96 the Web takes flight


WMCSA 1994


Different structure


panels to structure a range of topics


Models, system structure, file systems, application frameworks


Wiring the campus for wireless


Will anyone make money in mobile computing?


Networks, protocols, and exploiting the Web


Privacy and anonymity


The hot clients: PARC TABs, Newton+InfoTAC+ARDIS


Where will we be in 5 years?

The Five Year Outlook (in 1994)


Five teams brainstormed and reported back:


PDAs will make the world paperless


Entertainment and advertising will pay for all of it


Vertical apps and the mobile infrastructure will be in place


Global infrastructure deployed and the killer app has been
found (but they didn

t say what it was)


One theory was that web access will be the killer app


Discussion points


Role of entertainment


Is mobile just a variant of distributed computing


What clients will be hot next (unresolved)

Where we

re going


Stylus, pen, and speech input


Critical for internationalization as well as for mobility


The English (PC) keyboard is a limiting factor, while cellphones
(speech input, right?) are the fastest
-
growing computing appliance.


Exploiting image


The revolution in digital cameras has now happened


Social and legal issues will be as important as communications
infrastructure in gating/accelerating progress


What happened to privacy?


Copyright and the role of the entertainment industries


PDA
-
iquette


My suggestion


include discussion of these in WMCSA

From the client to the cloud


Power will always be holding us back


Inductive charging?


The

networked surface


has inherent appeal, if it also solves power
problems.


But how to overcome introduction obstacles?


High bandwidth up
-

and down
-
loading has arrived


File transfer, not necessarily interaction


Storage is ready to revolutionize client capabilities


Jetsend


CoolTown

s web primitives


Why was this necessary?


The smart watch, triumph of miniaturization, needs connectivity for
interesting apps


Systems issues


Opportunities to optimize at the lowest levels


Payoff in power and performance


Opportunities to organize communications better


Payoff in bandwidth savings


Opportunities to make applications more
understandable and manageable


Will the

resolver


make URLs and URNs work for us?


Payoff


maybe someone will actually use them

Protocols and networks


BlueTooth


will it happen?


Even with $7 chips now available, it will take a long time


To succeed, it needs to not be PC
-
centric


Is Internet II and IPv6 going to solve a whole class
of problems?


I think we will hear a great deal more about QoS and
reservation schemes. Present talks just tip of
iceberg.

Service and application enablers


Personal mobility


Is this just the universal personal phone number?


No, it

s open, not just automated Ernestine


But it needs a lot:


Negotiation between the sender and receiver


Where are the white pages?


Note: the culprits confessed that these are not yet in use


Will they graduate before addiction occurs?


Security proxies

Don

t forget the

user

!


Industrial applications of wearables, and ubiquitous
computing in the bio lab are pulling very hard.


Note that the highest leverage applications are multimodal


HCI issues are surprises


Unexpected behavior is hard to recover from


Collective behavior may also surprise us


Ensure that the base function is what the user wants
to sign up; the

smart part


is an extra incentive


Let

s get quantitative about usability and quality

Questions for the next WMCSA


Transcoder and proxy capabilities


Can system structure make major reductions in
bandwidth needs?


Feeding back the cost of surprise into the design
tools and building blocks


Impact of recognition technology in deriving context
and reacting to content


Apps, apps, apps


What are we learning from the motivated, but non
-
geek users?
