In 1994 Lauesen & Morten Harning invented a systematic design method (Virtual Windows) that gives a minimum of user screens, good data overview, efficiency for professional users, and fast development. The textbook User Interface Design - a software engineering perspective explains the method with several real-life projects, results of usability testing, the 68 defects dealt with during one of the projects, etc.
The book was written in 2004, where most systems were Windows-based. As a result, most of the cases look "old" today. They are not web-based. However, the Virtual Windows method works just as well for web-based systems.
How do you make a good user interface - easy to learn and efficient to use? Most books say it is trial-and-error. You reveal the errors with usability testing, but how do you correct the errors? Some are easy to deal with, but in practice many usability defects require major redesign. So making a good first design is crucial. This book shows you how:
In many cases, data presentation and data entry are not issues. It is a matter of showing data from the database with some explanatory texts, such as meaningful field names. In other cases overview of complex data is needed, and data must be presented as graphs, tables, diagrams, etc. Technically, this is difficult, and tools that combine complex data presentations with data entry require hard programming. See Data visualization for a solution where programming isn't needed.

If you want a quick view of how the Virtual Window method works, download the PowerPoint show. Warning: You have to see the slides in presentation mode. Click your way through each slide to see the story. The slides will take you step-by-step through a design example. Depending on your browser and operating system, you should either click the pps (presentation mode) or the ppt (once open, switch to presentation mode). Or you may have to right-click the link and save the target somewhere on your local disk. Then open it from there. (Sorry for the mess.)

Contains all the figures from the book. Most of them have some animation. There is one file for each chapter, plus several new slides for Chapter 3 (see additions below).
Pearson Education retains the copyright to the slides, but allows restricted copying for teaching purposes. It is a condition that the source and copyright notice is preserved on all the material. This means that you can show the slides, of course, but also modify the slides and make hand-out copies for teaching purposes, as long as you state the source and copyright notice.
The gestalt law of parallel movement: Download (pptx)
This file illustrates the gestalt law of parallel movement: Things that move in parallel are perceived as belonging together. You will see a shape (gestalt) moving. As soon as it stops, it disappears. How? (The book explains why. It illustrates many other gestalt laws, but cannot illustrate this one.)

A suggested course plan (curriculum) for a 12-week course in user interface design. The plan is based on my own experiences during many years of teaching the course. The book contains several training projects and exam questions. Additional training projects and solutions for some of the exercises are available for teachers. Since these exercises are mandatory on some courses around the world, we make sure the solutions are not available on-line. If you are a teacher, contact the author at email@example.com.

The addition to the book is five new sections for Chapter 3. They explain the typical patterns for showing data from a database (an E/R model), for instance as form-subform, table with detail window, etc.
PDA/Smartphone for ISS - 2006
Cleaning duties, inventory and payroll
Maternity benefit. Used by the parents, the employers (maybe several) and municipalities
The design guide is Julie's master's thesis. She started with some existing applications in ISS (facility services). She studied the cleaners when they worked, and observed what went on at courses for new employees. In this way she identified the basic usability problems with PDA user interfaces. Next she iteratively developed design rules while redesigning the user screens and testing the usability of the new design with several users.
One of the novelties was a simple and space saving handling of menus, buttons and other functions. They used too much screen space because designers followed the Windows style. Further she had observed that users had big problems finding these functions in the existing systems. She presents her solution in such a way that she introduces the Virtual Windows method at the same time.
The user interface deals with all these complexities, is efficient to use, yet elegant. The main screen shows all data, much of it on embedded tab-sheets. The top part shows a timeline of who has leave or vacation. A column indicates how much leave has been used and how much leave is planned. When there are several employers, each of them has a tab-sheet. Tabs are also used in case of more than one father or more municipalities. The screen at the right is part of Britt's paper prototype.
Britt designed a full paper prototype and usability-tested the entire user interface with several mothers, several employers, several officials and several iterations. She wrote and handed in the project report (92 pages). Next she presented the whole thing for the software house that had strugled with the project and challenged her.
They didn't believe what they saw. How long had she worked on this? Answer: 5 months - that is what a thesis project allows. It turned out that 40 developers in the software house had worked on the project for two years - without designing a single user screen. Furthermore, they had given up on serving all the parties in a maternity case (parents, employers and municipalities). In contrast, Britt had designed the system in such a way that all parties could see the same screens and tabs. This was convenient when parties discussed on the phone. However, for privacy reasons, some information was hidden to some of the parties.
The Virtual Windows method was a key part of the solution, and Britt wrote her thesis in such a way that other developers could see how the method worked in this complex case.
I have been teaching UX and systematic user interface design from the late nineties to 2016. Students learned to make great user-task descriptions, data models, user interface mockups and usability testing. However, they never tried to implement the database and the user interface. Many tools would be involved to do this in a professionel way. It dawned to me that MS Access was the only tool that could do it all. However, it was hard to learn. Existing documentation wasn't suited. So I spent almost a year learning the details of MS Access, the application screens (Forms) and the programming (VBA). The result was an Access tutorial to be used at the course. It uses a hotel reception system as an example.
We tried it in three semesters, but the conclusion was that it was too much to squeeze into one semester. Furthermore, technology had moved on to html, etc. However, for many years the Access tutorial was the most downloaded document on the IT-University's web-site. And I still (2020) get requests for help from people using the advanced parts of the tutorial. Unfortunately, we still have a gap: There are no other textbooks for teaching implementation of real user interfaces based on a real database. Furthermore, programming teachers cannot design user interfaces, and UX teachers cannot program. Only a few can design a real-life user interface.
The tutorial is still available. Most Access applications today use Access 2010, while the book shows screens from Access 2007. They are similar, but also have confusing differences. The book teaches you how to construct graphical user interfaces with advanced functionality. It covers database creation; user interfaces with windows, menus, etc.; database queries; and advanced user interfaces with Visual Basic. If you want a printed version, print on both sides of the paper, so that text and figure oppose correctly. The figures from the tutorial are available as: Access PowerPoint slides (zip+ppt).
There is also a free Visual Basic Reference card (pdf) (version 2007). Download the file and print it in colors on both sides of an A4 sheet, landscape mode. Fold it along the middle.
Hotel system: User mode (mdb)
Design mode (mdb)
Some readers of the Access tutorial have asked for a demo version of the hotel system. I have made the first functional prototype available (for Access 2007). It works for Access 2010 too, but menu details look wrong. Right-click the links and save the targets somewhere on your local disk. Then open it from there. As a typical prototype, it has many clumsy solutions. After making the prototype, I experimented with Access to find the clean solutions explained in the Access tutorial.
