Designing for Totality of Mobile and Non-Mobile Interaction: A Case Study

Shweta Aneja
Youn-Kyung Lim

The focus of the project is to design for mobile needs of users to support activities that closely relate to non-mobile contexts. We selected the real estate industry for a case study and conducted an in-depth research to gain a deeper understanding of the office (non-mobile) and mobile work environments of realtors and the social context of interaction with their clients. We identified some unique challenges that such a mixed work environment proposes. Recording contextual data in the mobile environment and streamlining it with huge amount of other related unorganized information in the non-mobile environment was identified as the main challenge. We designed an integrated system of a web-based application “REMAP” (for information analysis) and a mobile device “NotePod” (for information capture). The paper talks about some of the main research and findings, the design concept proposed, and finally some lessons learnt that we could extend to similar mixed contexts.


The LiLiPUT Prototype: A Wearable Lab Environment for User Tests of Mobile Telecommunication Applications

User trials for future mobile telecommunication applications inherently pose several particular challenges which are difficult to meet in a traditional lab environment. In this paper we describe LiLiPUT (Lightweight Lab Equipment for Portable User Testing in Telecommunications), a highly flexible wearable test system which has been realized as a fully operational prototype at the Telecommunications Research Center Vienna (ftw.). Then we illustrate how we use LiLiPUT for testing various types of mobile application in the wild.


Implementation of Interactive Poster 'SuiPo'

This paper explains an implementation of new media 'SuiPo,' or Suica Poster, which uses a combination of IC card ticket ‘Suica’ and Internet accessible mobile phone. Customers can get e-mail information by touching their IC card ticket on the reader located near the poster. Two pilot tests are conducted before the service has begun. The first test revealed that many people preferred the interactive poster but the registration process was complicated. The second test was conducted after improving the registration process. The lessons learned through two pilot tests are that in addition to the easier registration process, the increased popularity of two dimensional barcode reader in mobile phone has lowered the barrier of registration process. The SuiPo has been introduced in July 31st, 2006 and started service at Shinjuku Station and Tokyo Station. We hope the implementation would change customers’ perception of Suica not only as a ticket or e-money but also as an information tool.


Towards the Perfect Infrastructure for Usability Testing on Mobile Devices

Rudy Schusteritsch
Carolyn Y. Wei
Mark LaRosa

In this paper, we describe various setups that allow usability professionals to conduct effective user studies on mobile devices. We describe the factors relevant when building a solution for mobile device observation and the various designs we worked with in the Google user experience research environment as we iterated to meet changing study needs. We highlight several systems that can successfully be used in an industry environment, including a novel setup that is fully portable, can be used in a usability lab as well as in the field, accommodates a large variety of different mobile devices, and allows for live observation by product teams around the world.
