• Implementer of current mobile technologies
who spends quite a bit of time thinking
about mobile futures


Goal of this Presentation
To make you Think…

About interactions, the mobile context and data
when designing your next
mobile application & user experience

Because designing the User Experience goes
beyond UI Elements. And designers must embrace
“People Data” as a function of Human-Computer
Interfaces.


Why Context, Interactions & Data?

Individualize the experience
(made for or directed or adjusted to a particular individual)

People-Centric (Mobile) Computing

It is about designing software that is
Practical, Relevant and Interesting!
(to a particular target individual)


Why Context, Interactions & Data?
• Practical is about maximizing usability
– i.e. quick access to information with less clicks

• Relevant is about the information that matters
– i.e. tell me about deals in my current area

• Interesting is fun, and keeps users coming back t
your application
– i.e. “what a neat app”


Why Today?
Advanced features
Most personal and capabilities
gadget ever!

Faster networks, flat-rates,
fewer walled gardens, better
interoperability…

How to Enable?
• Make it easy for users to Reach and Interact
– Support many interactions

• Capture the Interactions and related Data
– the activities, the digital footprints

• Understand the Interactions
– Give the interactions meaning by applying the user’s
(mobile) context

• Classify, Analyze, Understand the Data; and adjust


Interactions
• Initiate application interactions
– Interact with physical objects, search, indentify
• The Interactions to support will all depend
– On your target audience
– Your application requirements, and existing
technology adoption gaps
• Interaction support can be costly

Interactions & Information Ubiquity
• Information Ubiquity is information everywhere
• Addressable (and thus identifiable) information, and/or
workflows for that matter
• Physical interactions, application triggers and physical
browsing. A number to call, a URL, a short-code, barcodes,
radio tags
– On books, magazines, posters, soda cans, billboards
– For advertisement, for authentication, for control, for quick action,
access to information
• Some interactions are more manual than others, some are
one way, others two-way
• The Mobile Handset is at the center of this ubiquity
phenomena

* Some interactions are user-initiated (pull-push) only, while others can be push as well


Interactions – Actions vs. Intentions
• An interaction can express Intent or Action
(i.e. fully realized transaction)
– Think about intent vs. action as weights applied
to the meaning of an Interaction
– Action has more weight than Intent
• Yet both are extremely valuable and provide
both explicit and hidden information
• Capture both; classify appropriately


Mobile Context

• “The user’s mobile context can be defined
as the set of and the intersection between
facts, events, circumstances, and
information that surrounds the (mobile)
user at a given point in time.”

• Enhances and augments the meaning of
each interaction, by providing additional
information about a given interaction

Mobile Context – Augmenting the
meaning of Interactions
• Interactions are more Informative
• Timely
• Accurate information (accuracy)
• Useful information (relevant)
• Connected (to friends and family, and other)
• Dynamic (always changing)
• Adaptive (to current circumstances)
• Transformational (promotes behavioral changes)


People’s Data


Data vs. Time
• Provides meaning only
over time

• Over time can be costly
to store.
– Leverage Web 2.0
services such as
Amazon S3


Data Analytics
• Interactions typically result on a Query
• Real-time analysis of interaction + context + digital
footprints + relationships to business data yields
relevant information
– Key to this is business data classification
– And the correlation algorithms such as time-based,
history, usage, probability-based recommendation,
business-rules, other
• Non real-time trend analysis of same data yields
hidden information over time for an individual or
groups


Data Analytics
• Interaction analysis can provide useful
information:
– Popular handsets; optimize application for
particular handset?
– Important regions; translate application to new
languages?
– Popular application features; features to
enhance
– Popular business data


Privacy, Users and Identity
• The young demographics seem not to care
as much for privacy (as long as something of
value is provided
• What about those who care?
– Provide identity abstractions that allows for
interaction and analysis without identifying
individuals


Effects on the UI
• The end result is a more practical UI, one
that requires less navigation and yields the
right information, faster
• The UI can be designed to take advantage of
the different Interaction-types, and even
make such Interactions simpler to use
• The UI can take advantage of user context
to improve or filter searches, and similar


People-Centric Mobile Computing
How all of this fits in?

1) Macro, 2) Contextual
and 3) Micro Views.

Behavioral economics or
computing is about
understanding human
and social factors to
better understand
(economic) decisions and
better influence the user.


Use Cases
• Retailers maximize promotions by delivering
promotions that matter to the user
• A user searches for a particular kind of store. The
query returns past stores of interest and
recommends new ones, all at walking distance
• User learns about or identifies a product or
retrieves a promotion by waving the handset (or
taking a picture of barcode) by object, poster or
magazine


In Conclusion
Because designing the
User Experience goes
beyond UI Elements,
designers must embrace
“People Data” and
“Behavioral Computing”
i.e. People-Centric
Mobile Computing, as a
function of Human-
Computer Interface
design.
