| Abstract: |
Designing the graphical user interface (UI) for operators in the control
room of SKA telescopes is a challenging task. The amount of
information to be shown and the possible stressful situations that
operators might need to handle in case of major problems makes the
design of the UI difficult. The UI has to be developed with goal of
driving the attention of the operator to important information and
of avoiding distractions, errors or delays due to the difficulties
in interpreting the UI. Not only the displayed content but also the
interactions between the textures and colours, symbols and areas
with different size, and the combination of these factors
must be taken into account when designing the UI for a specific
task.
Many studies have been conducted regarding the human
perception mechanisms and visual thinking processes. Based on the
results of those studies and on guidelines for helping the
graphical designers in developing effective UIs, we present a
summary of good practices to be followed when implementing the UI
for the control rooms of SKA. They cover topics like mechanisms to
capture the attention of the users when a change of state of the
system occurs, methods suitable for interactive visualisation and
how to utilise dashboards. Particular attention has to be
paid to the choice of colours. Finally, to avoid user overload,
appropriate drill down mechanisms to display information only when
needed are explored. |
