The HSI should support the user in maintaining awareness or recalling tasks that were interrupted or suspended by giving a reminder.
Additional Information:
A loss-of-activation error occurs when an intended action is not carried out due to a failure of memory (i.e., the intention has partially or completely decayed from memory). One way of preventing loss of activation is to have an on-screen message reminding the user of the suspended task. If necessary, the system should prompt the user with information on how to resume it. A second approach is to provide more display screens or implement a window-based display system to keep tasks that are in progress visible, as they would be in spatially dedicated conventional control rooms.
