week 9 – preamble

Hi All,

Before telling about tomorrow’s lecture; I have a reminder for you:

1. Forward the email that was sent to you when you ordered the Rejsekort (it has the Subject:Bekræftelse på bestilling af rejsekort and the sender is noreply@rejsekort.dk ) to Rune [ rune.fogh@gmail.com ]

2. Bring the actual Rejsekorts and hand them in to Rune

Until now we have collected 5 of them; so 5 is still missing.

Now; plan for tomorrow:

We have a guest speaker; Jesper Windum from Novo Nordisk. He is the co-author of the book Man-Machine Interface; he has been working in this field for quite a while, and his talk will be about his experience on designing MMIs.

Based on the duration of his lecture and the following Q/A; we might have a short exercise, which will be followed with project work. [ phase 1 of the final project ].

I have  posted a message on campusnet/website that is composed of some of the questions I received regarding the final project until now; make sure to check it out to avoid future confusions.

One thing I feel most of the groups have been lacking so far is ‘research’. (This also holds for the Rejsekort project). Your brainstorming sessions should be supported by proper research; how much of your ideas already exist, what kind of similar products/systems are out there, what elements of some non-similar product/systems might be used in your project, are there any sicientific work on this [e.g. google scholar], what about other universities/ public research projects …

These types of questions can significantly help you to precisely define the design problem, and then attack it with proper weapons…


Regarding the Final Project

Edit 29/10:

Q: Does it have to be a ‘completely new product’?

Answer: no, it is not a must.

Q: Can we make an app and use an existing tablet/device

Answer: it is fine to use an existing platform; but remember the physical aspects of the interaction too. Taking ergonomic aspects for the elderly into account; there are excellent opportinuties to design accessories/extentions. (There is also a huge market for these devices, with high profit margins)

One more thing: do research, because there might be already …



Let’s try to publicly answer some of the questions I received regarding the final project:

Q: Does it have to have a screen?

Short answer: no

Long answer: this is not a valid question. If your design considerations lead you to the need of having a screen, then you should probably have a screen.

Q: Is it ok if we do facebook for elderly?

Short answer: no

Long answer: no way

Q: Should we invent something totally new, or should we just look at existing systems and perhaps use something in a new context?

Short answer: yes and no

Long answer: Do research! Research is the single most important thing at this phase. You can do top-down research by looking at the market; what are the existing products, what has been used and what can be done upon them, and bottom-up research by interviewing and/or observing the potential users; finding out their needs by analyzing their routines.

Every product is interactive. Some more than the others. The important thing in this project is to find a good balance between physical embodiment and the interactivity. You should try to position your product/system in the green zone, somewhere between designing a hammer and a new social network.

week 8

Here are the highlights of the week:

7 stages of action

design questions related to 7 stages of action

conceptual models

mappings and the need for natural mappings




week 8 – preamble



Did you recharge your batteries during the break? You better had; we have a lot of stuff coming up in the following weeks.


Tomorrow; we will have a lecture on Product Usage; Mappings, Feedback, Constraints and Affordances, and it will be followed with project work.


Just to remind you; here is the timeline for the final project:


Phase One (Project definition, req. analysis …): November 15th

Final Report: December 7th

Final Demo+Presentation: December 15th


Another reminder: Please bring the receipts for the Rejsekort and the Rejsekorts themselves; and give them to Rune…


See you tomorrow,



Usability Evaluation of the Rejsekort – Travelcard system

As promissed, here are 9 reports from 42072-Design for Interaction students on the usability evaluation of Rejsekort System; which is being rolled out in Denmark right now.

Rejsekort is particularly interesting from point of interaction design, because it is a drastic shift of the ticketing system; and it is first-of-a-kind in the sense that all other ticketing methods will eventually abolish and you will be able to travel from any given point A to point B in Denmark using a single card.

Of course paradigm shifts does not happen overnight or they don’t happen swiftly; new technologies, methods and devices all come with their own problems. In the course ‘Design for Interaction’ we looked at the system from usability point of view; and tried to identify what types of issues might occur during normal usage of the system.

Two complementary types of evaluations were conducted; user testing (with min. 5 users) of the representative tasks, and heuristic evaluations by the students (educated/expert users).

56 students conducted the evaluations in 9 groups; and below you can find the reports.

      preferred way of viewing this report is through Issuu

Group 6 has a companion website – and a home-made Rejsekort Simulator!

week 7 – preamble

ladies and gentleman,

Tomorrow is the day; and remember:

1. We are meeting at 8:30 in the classroom, please be on time

2. Reports are also due by 8:30 – if your deliverable is not in my mailbox – dtu42072@gmail.com with the subject line “Project 1 – Group X” by 8:30; I will be very, very sad.

We are aslo fortunate to have Gregers Morgensen, from Rejsekort A/S; he will give a brief presentation about the system, and then we will have an open discussion. One thing I would like to remind you is that, he has no chance to see your reports beforehand, and he might not have the chance to address some very specific questions. Remember that he is doing this as a favor, and we are not interrogating him -take tomorrow’s discussion as an informative form of communication.

Also remember that he –and the rest of the people in the world whom has internet access– will be able to reach your reports as they will be up on our website.

I am looking forward to read your max-300-page reports.


week 6

Slides for week 6 is now on campusnet.


Yesterday’s lecture featured a video by Hans Rosling, a medical doctor and a professor in public health. He appeared on TED a few years ago, and gave a very interesting talk; which can be watched here. Furthermore; he has an interactive websiteGapminder, where you can play with many different stats.


Next week: Remember that the course will start at 8:30, and Gregers Mogensen from Rejsekort A/S will be there to give an overview of the project.


Deadline for the delivery of project I is also tuesday morning by 8:30:00 GMT+1 (strict). Please deliver as a PDF file to dtu42072@gmail.com with the subjectline: “Project 1 – Group X”.


I saw your progress yesterday, all of the groups are in good shape and some were impressive work…
