Coping with consistency under multiple design constraints: The case of the Nokia 9000 WWW browser

Consistency is a commonly accepted but sometimes problematic design goal. External and internal consistency may conflict, and sometimes the best solution is inconsistent in both respects. We describe user interface design issues and several usability studies for the Nokia 9000 Communicator WWW browser and for WWW pages optimised for the browser. The results show how within the same, restricted design domain, different forms of consistency have to be favoured over others in solving various design problems.

Special issue on out-of-box experience and consumer devices

Abstract“Computer equipment is hard to choose, install, maintain, and, especially, operate” (Landauer 1995 In: The trouble with computers: usefulness, usability, and productivity). How many cables did you have to connect (and organise) before the personal office system was properly installed and put into use? How many set-up procedures and agreements did you have to complete before you could access your e-mail with your mobile phone or PDA? Did you lose any documents or applications when you replaced your old computer with a new one? Computers, mobile devices and information technology products are sometimes difficult to put into use because of the several operations required prior to their first use.

On User Experience Measurement Needs: Case Nokia

Measurements related to user expectations, behaviors and experiences can provide useful data to many roles and teams in a company. Each role provides different views to the question “what should be measured, and why?†We conducted an empirical study on user experience (UX) measurement needs at different units and levels in one corporate (Nokia) and asked which kinds of UX measurements would be useful for different functions. We identified common UX measurement needs on 8 different themes.

Enabling and improving the use of mobile e-services

The present workshop addresses ongoing standardization issues for user education and setup procedures, enabling and improving the startup and use of mobile e-services.

ToyMobile: Image-based Telecommunication and Small Children

Small children are not able to use existing communication devices without errors because they are unable to read and because devices typically require faster input than children are able to provide. If an error-proof communication device is designed for small children, it must contain an extremely simple user interface with visual and auditory input and output. In this study, we identify the interaction capabilities that small children have, show everyday problems that 3 and 5 year old children may have with phone management through simple experiments, and, finally, present a simple prototype, ToyMobile, that is built through cooperative inquiry and design with children.

Concurrent Usability Engineering

Usability engineering lifecycle models have problems matching with concurrent product development practices. In this paper we describe what problems there are between usability engineering lifecycle and concurrent product development process and describe an example how this problem is handled at Nokia Mobile Phones.

Enabling and improving the use of mobile services: the role of user experience standards and interoperability

This special session Panel will present and discuss the importance and potentials of user experience, based on the insight and results achieved through recent standardization efforts in the European Telecommunication Standards Institute (ETSI), Technical Committee Human Factors (TC HF). The work was sponsored by the European Commission and the European Free Trade Association, under the eEurope 2005 action plan. The work focused on enabling and improving the use of mobile services through improved, more usable and consistent user education [8], mobile setup procedures [7] and an optimized user experience, applied to the user experience optimization and interoperability of the 3G/UMTS and mobile broadband environment [9].

Techniques for designing mobile applications with customer data

This SIG provides a forum for discussing how customer-centered techniques can best be used to gather requirements for mobile applications, especially considering the possibilities that new technologies offer. We will discuss when and how to modify customer-centered design for initial requirements gathering and during paper mock-up interviews. We will also share ideas for involving end users in visioning new possibilities for mobile platforms and key principles for designing applications for mobile devices. We start by sharing our experiences and then lead participants through discussions of their experience and challenges recording our collective knowledge for the CHI community.

The right to information: setup of mobile terminals and services

The Technical Committee Human Factors (TC HF) of the European Telecommunication Standards Institute (ETSI, www.etsi.org) has initiated the development of guidelines for the design of setup procedures, applicable to mobile terminals and e-services.This work is performed under the policy framework defined by the e-Europe 2005 action plan, by and in close collaboration between major industry players and ETSI.The goal of this activity is the development of design guidelines for user interface and service developers based on specific use cases which help to understand the difficulties users are experiencing when configuring their devices or accessing the services.The result of this work will be presented at the conference and the resulting ETSI Guide will be available free of charge.

Usability Engineering Milestones In Complex Product Development — Experiences At Nokia Mobile Phones

How can usability engineering be managed in highly complex innovative product development? When usability engineering is performed in Concurrent Engineering (CE) product development, there are stages where usability engineering needs to be refocused in order to perform successfully in the changing project environment. The focusing points follow the product development milestones but are not identical with those. From usability engineering perspective those points are critical for achieving effectiveness and efficiency in the product development.
