Library Mobile Computing Project

Indiana State University Library

Ralph Gabbard, Judy Tribble, Paul Asay, Chris Hayes, Joe Rayes


ISU Background

  • Comprehensive university

  • 11,000 students

  • Students from rural areas and lower socioeconomic backgrounds


ISU Library

  • Current building opened in 1973.

  • Over 1 million volumes on five floors.

  • Graduate and faculty carrels are not currently networked.

  • Over 60 databases available through the library home page.


Inspiration – Cornell’s “Live From the Stacks

  • First, mobile document scanners.

  • Second, mobile computers.


The Mobile Project Plan

  • Mobile Project Plan.

  • Planned workstation syncing prototype.

  • Investigate wireless LAN’s.


Project Plan Goals & Objectives

  • Team approach.

  • The goals.

  • Problems encountered.

    • Networking.

    • Security.

    • Usability.

    • Costs.


Scenario One

  • A patron enters the library. At the main desk, s/he checks out a hand-held scanner. The patron takes the scanner into the stacks to scan text and graphics from books, journals, and other printed materials in the library.

  • Before leaving the library, the patron can print or transfer the scanned files to the his/her disk or laptop computer for use in electronic documents.


Scenario One, Handheld Scanners

  • HP CapShare 920 mobile e-copier.

  • Checkout procedures.

  • Downloads via infrared port.

  • Bundled Pagis pro software handles text conversion.

  • Required a “Download” workstation.


Mobile E-copier Details

  • While fairly simple to operate, it did require advance software, and infrared capable transmission.


Lessons Learned

  • Usability testing and prototyping

  • Training

  • Problems


Scenario One Costs

  • HP Capshare Scanner Costs: 4 @ $279.00: total $1116.00.

  • Extended Systems Infrared USB Adapters: 4 @ $54.00: total $216.00.

  • Watchdog cards: 4 @ $85.00: $340.00.


Evolving Workstations

  • Library workstations currently have only one “look”.

  • “Download” workstation addition.

  • Later add an express kiosk station.

  • Switched workstation security to Watchdog internal cards.


Scenario Two

  • A patron enters the library and using a mobile computing device, the patron:

    • searches the on-line catalog,

    • interacts with others on the network

    • takes and records notes

    • Locates books and other materials


Scenario Two, Parts 1-6

  • Parts 1 and 2 – Install wireless network

    • Part 1 – “wire” faculty carrels

    • Part 2 – “wire” rest of building

  • Part 3 – Test handhelds and PC cards

  • Part 4 – Set up mobile web site

  • Part 5 – Install reference chat room

  • Part 6 – Develop book locator software


Setting up the network

  • Wireless network access in all faculty carrels.

    • High potential for mobile device usage.

    • Lower cost than wiring 54 carrels.


Wireless Network Infrastructure

  • Mobile computing required an effective wireless network.

  • We settled on a combination of 802.11b components from Cisco and Compaq.

  • Both comply with the WI-FI standard.


Wireless LAN Site Survey


Carrel Wireless Costs

  • Total hardware including 7 Cisco access points, and 10 wireless cards: $8,123.00.

  • Total installation costs including wiring, and power: $2,100.00.

  • We conducted the site survey ourselves to determine the number and location of access points.


Setting up the Network– Part Two

  • Extend the wireless network into every public area of the library.


Wireless LAN Site Survey


Rest of Library Wireless Costs

  • Total hardware including 17 Cisco access points, 8 Compaq PCI/software access points cost: $18,042.00.

  • Total installation costs including wiring, and power: $5,100.00.


Choosing Handheld OS

  • Several choices of handheld computers, but few that are network capable.

  • Limited choices available: Palm, PocketPC’s, Psion, and Win CE handheld PC’s.

  • Garfinkel, Simson. “The net effect: handheld heaven.” TECHNOLOGY REVIEW, January/February 2001


Compaq iPAQ 3650 PDA.

Includes expansion pack for PC cards.

Compaq WL100 wireless network card.

Syncs via USB cradle to download workstation.

Handheld Specifics – Developmental Phase


Handheld Costs – Developmental Phase

  • Compaq iPAQ handheld with wireless cards and expansion packs costs 2 @ $720.00: $14200.00.


Mobile Web Presence

  • Screen capability on mobile devices may force you to rethink your web presence.

  • Potential use of a WAP server.


Scenario Two – Part4 – http://mobile.indstate.edu


Scenario Two, Part 5 – Reference Chat

  • While in the stacks, the student can ask a question of a staff member via chat software.

  • Used chat software which could be accessed from more than one workstation.

  • Restricted by IP authorization.


Scenario Two – Part 6 Book Locator

  • While in the stacks the user can search the catalog for a book, find a call number, then use Book Locator to determine which floor and shelf the book occupies.


Considerations for the Near Future

  • Handhelds, notebooks, tablet size pc’s, and web enabled cell phones.


Future Directions

  • E-pop.

  • Changing workstations.

  • Providing students with a library workspace.

  • Support the rapidly changing mobile environment.


Conclusions

  • Mobile computing in the library is feasible and may serve users better than wired networking in specific cases.


Conclusions

  • The library is a good place to prototype mobile computing on campus.
