If a soft control can be accessed from more than one location in the HSI, protective measures should ensure its coordinated use among multiple users.
Additional Information:
The HSI should be designed to allow operators to maintain awareness of each other's use of the soft control so their actions do not interfere. For example, two operators should not be able to operate the same soft control simultaneously from different places without being aware of each other's actions. Coordination problems may be minimized by assigning the control capability for a soft control to a particular individual or workstation (e.g., while the settings of a soft control can be viewed from multiple display devices, it can only be operated from one device). Alternatively, coordination may be supported by features that restrict access to soft controls one user at a time, and group-view displays that allow operators to observe each other's actions.
