Abstract
A major challenge in doing User-Centered Design is getting rapid and representative user input. A simple mechanism is described that uses the Web in building a participant recruiting database and carrying out Web user surveys. A recent study of desktop user interface usage is used to illustrate the mechanism.

Overview
Despite the increase in focus on ease of use and usability within the computer industry, many product teams still forego involving users in the design and evaluation of their products due to the difficulty in getting ready access to representative users and the lack of rapid turn-around techniques to get user input. In fact, even groups who have embraced User-Centered Design in the past are finding it increasingly difficult to involve users given ever decreasing development cycles, or the new so-called "three-month web-year" phenomenon. In addition, the increasing focus on designing for an international audience drives a requirement to gather user input from a world-wide sample.

Approach
The approach our team developed for addressing these challenges involves two fundamental elements using the World-Wide Web. The first is a participant recruiting database and the second is a survey mechanism.

Participant Recruiting Database
This component of our approach is comprised of a demographics and product usage survey on the internet, a central relational database and web query interface on the intranet. Potential participants complete the web-based form asking them information such as name, address, e-mail address, characteristics of their computer use, and information about the specific products they use and their proficiency at using them. It also asks the type of studies for which they would like to be considered - web survey, telephone interview, on-location study, etc. Designers and other practitioners within the company then use the intranet query interface to the database to select random samples of particular user characteristics for specific studies, of whatever type. If a web-based survey will be conducted with the selected sample, the e-mail addresses are used to invite potential participants. The query interface also records the studies for which the names were used to avoid participant study fatigue.

To ensure the database would be as representative of the population of users as possible, we identified the list of market segments, products, and user types that our company targets with our products, then found the usenet groups that the users in these categories used frequently and invited those visiting the usenet groups to help us design our products by registering themselves in our database. To increase the response rate, we offered a notebook computer to a randomly selected respondent who added him/herself to our database. Realizing that we still may have some bias in the sample, we also regularly check the demographics of people in our database with demographic information available on selected populations. We have recently also included our company product registration database records into our recruiting database to further increase representativeness. Designers and other practitioners can now identify and invite a sample of representative users within minutes using this database.

Web Survey Mechanism
The second component of our approach involves a web survey mechanism that provides teams with survey templates for conducting the most commonly requested surveys. This includes customer satisfaction, requirements gathering, task analysis, icon recognizability, terminology evaluation, design review, etc. The most frequently used surveys, such as for customer satisfaction and requirements gathering, are automated in that practitioners can simply provide the product name and questions they would like to ask in addition to a standard set we provide, press OK and the survey is on the web. Participants are selected using the recruiting database and invited via e-mail. Within minutes the design team is receiving user input on the intranet site where results are automatically analyzed and displayed. In cases of more customized surveys, practitioners are provided templates on the intranet website that they then modify at will, submit to have posted to the web, and get files with the aggregated results sent to them via e-mail.

Results
Our experience to date with these two components used in combination shows that we can build surveys in minutes and get 60-70 percent response rates with all information typically collected within two to three days.

Example
The characteristics of the mechanism are best illustrated by example. Recently, one of the teams within our company needed to have information on the use of the various user interface elements of the Microsoft® Windows 95™ desktop. However, the team was on a very tight development schedule and decided they didn’t have the time or resources to conduct the required study. It was then suggested to the team to consider using our new mechanism, which they did. The survey was constructed, the participants selected and invited, the data collected, analyzed, and presented back to the team all within three days. The results yielded important insights for the team. They learned that the majority of users do not change settings on the interface from the defaults and little use is made of advanced features. For example, the majority leave the task bar at the bottom of the screen with auto-hide turned off. Results also showed that despite having higher resolution monitors, a large number of users maximize windows and switch between them using the task bar. Results like these had a major input on the subsequent design direction. Comments from the teams like this one that have used this approach have been extremely positive. They realize that the use of mechanisms like these for rapidly collecting input from representative users not only increases the knowledge they have of their users but also allows them to collect this information when they don’t have the time to do so using traditional methods. The input is also from an international sample. Despite their speed and power, it should be pointed out, however, that these methods should not be used as a replacement to all of the typical User-Centered Design methods and techniques. They should augment the traditional methods in critical projects in cases where there is extremely time pressure, where a larger sample is desired, and where a world-wide audience is important. In certain circumstances where a project would normally get no user input, these mechanisms can be used to ensure that some user input is collected.
