• The Hype Cycle

• Some suggestions

Defining “library”

• The library catalog

• Library services in general

• The institution providing the library

• Links from the wider world

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

5

The Library Catalog

• A scaled-down version of the full search interface

• Search result details are also limited

• Some indicate if titles are available

• Some provide a way to request an item

The Library Catalog

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

Library Services

• For mobile users, the catalog is not the only service of interest

• Library hours, reserving a room or computer, checking out materials, paying fines, reading e-resources

The institution providing the library

• Promotion can work well for an institution-focused app, including library services

• A one stop shopping advantage

• Other app features provide gravitational pull

Links from the wider world

• Libraries surface in shopping apps

• A way for the library to be seen in the flow of popular apps, without the user having to focus first on the institution or library

Defining “mobile”

• A medium, a concept, devices, networks

• Blurring distinctions between feature phones and smartphones

• The past: slow networks, constrained data entry, small screens

• The future: fast networks, bigger screens, improved keyboard input, voice recognition

• Maybe it means “ubiquitous”, or “always with me”

16

Defining “apps”

• Convenient shorthand, or horrendous jargon, depending on your point of view

• An application

• Might be a “native” program for a specific device

• Might be a website that is designed with mobile devices in mind

• Might be a widget, or an embedded feature in someone else’s application

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

17

Mobile Apps for Library Services

• Some libraries have a mobile web interface

• A few libraries have developed native apps

• Many library websites are not mobile-friendly

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

18

Mobile Web Apps

• Content is served by a website

• XHTML optimized for mobile

• Widely accessible

• Optimizations vary a lot

• May not be accepted by some mobile marketplaces, e.g., the iTunes App Store

• Some mobile device features unavailable (Geo-location, local data storage, camera, inter-operability with other native apps)

Mobile Native Apps

• Written for a mobile operating system, e.g., iPhone, Android, Palm, etc.

• Significant effort to support all mobile devices

• Mobile developer communities are growing

• Device features (camera, microphone, speaker, GPS) are all available

• HTML5 technologies may push the pendulum back to web apps, for capable mobile browsers

Strategic Choices

• Access to a catalog or something else?

• Native or web app?

• One device or several?

• App code built, bought, or borrowed?

• How much to invest?

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

23

Native vs. Web

• Strong advocates of both

• Easy to get absorbed in the arguments

• As with most things in life, when determining which path to choose, the choice comes down to “it depends”

Research Mobile DevelopmentTAI CHI Webinar Series, 29 April 2010

Developing apps for one device

Sometimes it makes good sense:

• You require a feature that only that device supports

• The device’s market is big enough, for you

• You know all of your app users have the device

• You’re experimenting

Library Mobile App Hype Cycle – Where are we?

Expectation, then disappointment

“ … it is tempting to wish that this cycle of

expectation and disappointment could be

avoided. In fact, the cycle is an essential part of

the innovation process. It is a collective measure

of our goals, and the distance that must be

traversed in order to realize them.”

Saffo, Paul. “’Revolution’ the Hype Word of Computer Industry Advances." InfoWorld 4

Feb. 1991: 60. Print.

iPhone Apps and the Long Tail

“The average iPhone or iPod Touch owner uses 5 to 10

apps regularly, according to Flurry, a research firm

that studies mobile trends. This despite the surfeit

of available apps: some 140,000 and counting.”

Hafner, Katie. "When Phones Are Just Too Smart." The New York Times. The New York Times

Company, 29 Jan. 2010. Web. 24 Feb. 2010..

What counts as success?

• More use, not just the same use on a different

device

• Fewer clicks per transaction

• New uses

• Moving library services into the flow

Some suggestions

• Mobile devices are reaching your content. Make that work.

• Work with, and improve, existing library mobile applications.

• Don’t disenfranchise users of mobile devices that tend not to browse the web.

• Study user needs, study results of use, and refactor accordingly.

• Report your study results to the library community.
