Phenom-World’s goal was to build the first personal table-top electron microscope.

Sioux developed the complete software suite for the Phenom. This includes hardware control, image processing (Pro-Suite), user interface and multi-language support. Sioux also developed all electronic hardware (including high-voltage electronics and the wiring) and produced and tested all electronic boards. On top of that, Sioux created the mathematical algorithms and the remote diagnostics. 

Phenom-World is now a leading global manufacturer of desktop scanning electron microscopes and imaging solutions for submicron scale applications. 

Their newest product consist of an updated UI that maximizes the workspace. A high-level design concept was made by an external design agency. For substantiated and elaborated UI directions, the Sioux UX Competence was


My activities during these projects:

  • Usability testing
  • User interface design
  • Stakeholder meetings
  • Working closely with the UI developer


The Sioux UX Competence was involved to create a well-founded design. With the nearing deadline and an overflowing UI backlog the decision was made to prioritize the developments. Usability testing executed to find pain points. The candidates were recorded and were asked to fill in the user experience questionnaire.

The results from these test were collected in a rainbow sheet, from thereon we made a selection of major and minor points to tackle. These results were shared with the stakeholders and developers. Because of a tigh budget a deadline it was decided to tackle the minor points first, orr as we call them the low-hanging fruits.

These low-hanging fruits consisted of the multi-button toolbar, side panel, gallery viewer, and the settings menu.
