2.6 Software user interface

This chapter contains information about the structure and use of the software implemented menu structure.
This integrated software controls instrument operations, including calculation and evaluation of measured
data, displaying results and information screens, storage and retrieval of data.

2.6.1 User interface

The user interface of the HumaFIA analyser is designed to be intuitive and easy to use and provide access
to all user level functions. The user can interact with the HumaFIA by using only the touch screen and the
virtual on-screen keypad, or by using an external keyboard.
2.6.1.1 Using the touch screen
The touch screen is a capacitive sensor behind glass. It must be operated by finger, or a conductive stylus
designed for capacitive touch screens, as it is not sensitive to pressure. The touch screen allows selection of
menu items and 'pressing' of buttons by gently tapping the surface over the selected item. The touch-screen
device used in the HumaFIA analyser was selected for its reliability, endurance, and compatibility with the
medical laboratory environment. Simple operations are supported, but multi-touch gestures or multiple
tapping are not supported. The surface glass material is resistant to liquids. However, it should be dry when
in use, otherwise it may not work reliably. Use a damp cloth to clean the glass surface when the analyser is
turned off.
2.6.1.2 Button colours
Activated buttons are displayed either in red with white icons or in dark grey with white icons, while inactive.
Upon selection they turn to opposite colours. In case a button is not selectable, it remains greyed out.
2.6.1.3 Entering information
HumaFIA sometimes requires the operator to enter information such as sample ID or patient data. To enter
information into a data field, simply tap or click on its box. The data field will change colour, indicating that
data entry is active for that field. Enter information using the virtual on-screen keypad or with an optional
external keyboard.
Data is not saved until the user presses Enter or Save or Accept to proceed.
2.6.1.4 Home screen
The Main menu will appear after start-up or when the HUMAN logo is pressed in the menu headline.
