Free HMI Check

How well does your operator screenhold up in an upset?

Upload a screenshot of your HMI, control room display or machine software. You get a report with concrete findings and fixes, reviewed by hand, within 2 working days.

  • Annotated screenshot with 10 to 15 findings
  • Severity, reference and concrete fix for every finding
  • Score for heuristics, accessibility, UX laws, ISO 9241-110 and industrial practice
  • Free, one screen per company
Example: 15 findings on a fictional pumping station display

In 3 steps

How it works

  1. 1

    Upload a screenshot

    One operator screen, ideally with two sentences of context: plant, operators, monitor and distance.

  2. 2

    We review by hand

    A UX designer with industrial experience reviews the image. If something is unclear, we ask by e-mail.

  3. 3

    Report in 2 working days

    You get the report as a PDF by e-mail. If you like, we walk you through it in 30 minutes.

Your screenshot sits in private storage, with no public link. We delete the screenshot after 90 days at the latest, or right after the report if you ask.

No newsletter, no selling of your data. We never store screenshots publicly and delete them after 90 days at the latest.

Your report

What you get

A PDF report, structured so your engineering team can work with it right away.

  • Annotated screenshot

    Every finding as a number right on the image. You see at once where the problem is.

  • Severity

    Critical, high, medium or low. So it is clear what goes into the next release.

  • Reference

    Nielsen heuristic, WCAG criterion, ISO 9241-110 or ISA-101. Helps the discussion in your team.

  • Concrete fix

    What to change, in colours, texts, sizes and spacing. Plus a score per area and a recommended order.

Sample report

What the report looks like

Excerpt from our sample report for a fictional pumping station: three of 15 findings and the score per area.

Fictional example. We built the screen, plant and values ourselves so you can see what you get. No client, no real plant.

Overall

Frameworks

What we review against

Five frameworks that work in industry. We use the standards as a reference for good practice, not as certification.

  • Nielsen's 10 heuristics

    • Visibility of system status
    • Error prevention and error messages
    • Consistency and standards
    • Recognition rather than recall
  • Accessibility per WCAG 2.2 AA

    • Contrast of text and controls
    • Target size of buttons
    • Text size
    • Signals not by colour alone
  • UX laws

    • Fitts: size and distance of targets
    • Hick: number of options
    • Miller: grouping of values
    • Jakob and Gestalt: expectation, proximity, similarity
  • ISO 9241-110

    • Suitability for the task
    • Self-descriptiveness
    • Conformity with user expectations
    • Error tolerance and controllability
  • Industrial practice

    • ISA-101: greyscale, colour only for deviations
    • Alarm display per ISA-18.2 and EEMUA 191
    • Operation with gloves
    • Reading from a distance

Confidential

  • Your screenshot sits in private storage, with no public link.
  • Only Beabstracto sees the image. We never show it or use it as a reference.
  • For a first draft we may use the Claude API by Anthropic. A person reviews and sends every report.
  • We delete the screenshot after 90 days at the latest, or right after the report if you ask.
  • Need a non-disclosure agreement first? Write to contact@beabstracto.com.

Frequently asked questions

What does the HMI Check cost?
Nothing. We review one screen per company for free. Afterwards you decide whether you want more.
What happens after the report?
We offer you a 30-minute walkthrough. No newsletter. If you do not want a walkthrough, that is the end of it.
Which screens fit?
Machine HMI, control room, SCADA, MES, operator software and industrial dashboards. PNG, JPG or WebP up to 10 MB. A photo of the panel works too; a screenshot is better.
Does this replace a usability test?
No. The review finds known patterns quickly. How your operators react in an upset only shows in a test with them. We offer that if you want it.
Why does it take 2 working days?
Because a person reviews it. We measure contrast and convert sizes to your monitor and viewing distance.
Several screens or whole workflows?
The free check covers one image. For several screens, workflows or an old versus new comparison, we send you a quote.

One screenshot is enough to start.

Within 2 working days you get a report your team can work with right away. Free of charge.
