The Most Advanced UX-Lab in Europe

uxlab toolbox.png

We have one of the most versatile, precise, and valid usability test laboratories that provide the reliable data-driven foundation needed to qualify design. Unknown to many, psychology has a long tradition in testing and quantifying human experiences. Our test and analysis competencies are therefore naturally qualified by our psychological backgrounds. In addition, 1/4 of our team holds formal research backgrounds that further extends our methodological reach.

We, therefore, have the most professional team to carry out the regular usability testing you need regularly. Our clients also rely on UXLab to design and conduct special tests aimed at testing technologies or experience qualities that the regular usability tests cannot.

When it comes to facilities, our lab is naturally also best in class.

Below you will find an outline of the four main types of testing we do:

For test participants you can read about our privacy regulations here ☞ (In Danish).


Perceptual Testing

Typical SDA-based servcies

  • Screening of graphical layout strategies to support easy differentiation.

  • Risk profile of product mix-up based on quantitative data.

  • Packaging design quality assessment.

Typical PeCo-based services

  • Decompositon of user experience into design components and systematic optimisation of these based on quantitative market feedback.

  • Sensory profiling of design to drive design maturation

SIGNAL DETECTION ANALYSIS, SDA

We have uniquely introduced signal detection analysis into the design process of companies where robust and safe visual discrimination of products is safety-critical.

We have uniquely introduced signal detection analysis into the design process of companies where robust and safe visual discrimination of products is safety-critical.

For a variety of design challenges, we need to know how users experience the world. For safety-critical design, we measure the perceptual, sensory quality of visual design to pinpoint which colours and graphical design that is most easily discriminated and thus robust towards errors.

SDA provides quantitative data about the robustness of fundamental sensory qualities of your design, i.e., does your design communicate clearly? Many design decisions rest on a holistic evaluation of all design components without a precise understanding of the quality of each individual components (e.g., colour, font, graphics, etc.). SDA gives a quantitative profile of the sensory quality of each of those components and how they may interact in getting your message across.


PERSONAL CONSTRUCTS, PeCo

Personal constructs extracts the dimensions along which users experience a particular design. These dimensions are then quantified to reveal the primary qualities that affect user acceptance and preference. PeCo supports both exploring what to design and how to design it right. With PeCo critical design dimensions can be systematically studied and settled in the early phases when design freedom is largest and the cost of design changes the lowest.

Diagnostic Testing

  • 5-6 persons

  • Lab. / Remote / On-site

  • Root cause analysis

  • Design drivers to improve design

Sometimes during design development, you come across a design problem where users are just not getting it right, and your design team is at a loss what to do. There are likely many ideas but what you need is the root cause understanding and the right solution moving forward. This is where a diagnostic test helps out.

The same problem may arise with products or services that are already launched. You may need a quick fix to mitigate the problem (maybe to avoid a recall).

A diagnostic test can also provide a clear and operational project scoping before moving into a refresh or a line-extension of an existing product or service.

As a supplement to the diagnostic test, we recommend the expert-based UX-Review. The review is based on our detailed expert knowledge of what drives good design. The UX-Review is carried out by two senior UX-experts. All findings and design recommendations are clearly linked to our analysis tool to provide full transparency to avoid “opinion-based” recommendations.


Examples of Diagnostic Testing

How to Convince in the First Five Minutes?

PhaseOne wanted to know what it would take to convince professional users of competing software products to switch to their photo editing platform CaptureOne. Especially, PhaseOne wanted to explore how users would engage in a five-minute coffee-break-style evaluative walkthrough of their product. What do professionals look for, and how can CaptureOne convincingly demonstrate the superior functions and technology?

DPsy answered the question by designing a diagnostic user test that provided very concrete design drivers for how to support the 5 minute “test-run” use case. Best of all - the user test took the project in a very different direction from what PhaseOne initially conceptualised.


Formative Testing

  • 6-8 persons

  • Lab. / Remote / On-site

  • Root cause analysis

  • Design drivers to improve design

  • Design control

We carry out design control and quality assurance (QA) adhere to the business relevant standards

A formative usability test is what most merely refer to as a usability test. Since this kind of usability testing is typically used in the design phase to push design forward - forming it, it should rightly be considered as a formative usability test. This is not just semantics. With the formative test approach comes an often overlooked vital component: design control.

To carry out a meaningful formative usability tests, you need to precisely know what requirements you are testing (validating) against. If you are serious about usability testing, you need to have a clear understanding of your design requirements (whether they are driven by e.g. technical constraints, regulatory compliance or user driven) and how to develop and optimize your design within this pre-defined design space. We have the tools and expert knowledge to drive those formative tests and ensure your design development is moving in the right direction.

Summative Testing

As a final preparation for a submission for approval of medical devices, a summative test is needed to document safe use for all relevant users.

As a final preparation for a submission for approval of medical devices, a summative test is needed to document safe use for all relevant users.

Summative testing is predominantly used in regulated industries such as healthcare where clear documentation is needed that the design lives up to the intended uses for all intended users in the respective use context. We carry out summative testing of med.tech devices in the US together with strategic collaboration partners in the US.

However, we also employ summative testing methodologies to document the behavioural interaction qualities of the design. Documented UX claims are part of a business strategy for some of our clients that in addition to outstanding technologies deliver value to their customers be also having exceptional interaction quality.

Haven’t Found the Test You Look For?

The above was just a sample of the most common test types we use.

In addtion, we have many other specialised tools that can inspect your design and provide both qualitative and quantitative data to support your design decisions.
