It is possible that the window will show a sphere (or shape model) with a latitude-longitude grid, indicating the orientation of the asteroid in the images (rather than the position of the asteroid), or when closer in, the position of the WA image on the asteroid.

What follows is the translation of the pop-up caption of the display area, to the best of my ability, and as precisely
as possible.

"The position and the size of Ryugu as seen by the camera. In the vicinity of Ryugu Hayabusa will be
approaching it while capturing Ryugu's external appearance."

Position? , why should it matter?
Size?, we know it by now.

Caught!

From now on, the asteroid's gravity will dominate the area (Hill area: within about 90 km from the asteroid) will enter!

I think this old PDF explains what is going to happen, although I can't translate it (see p.19):
http://fanfun.jaxa.jp/jaxatv/files/20180419_hayabusa2.pdf

Probably by "schematic" they mean a 3d model.

I think the box will show Hayabusa attitude w.r.t Ryugu during various operations. I whink it will look a lot like a Star Trek Enterprise screen! :-)

I think information on training will be of interest to forum members. My translation will follow for the few pages
on training as follows.

P

Page 16:

Operation training

・LSS(Landing Site Selection) training

Aim: Find out, from technically and scientifically meaningful viewpoint, if our limited resources inluding time
can actually land the mother ship and rovers onto the asteroid surface. 

・IRIO (Real-time Integrated Operation) training:

Use of simulator for landing and proximity operations in critical situation in real time to increase proficiciency
of operation members.

Page 17:

RIO training objectives:

We want to increase the operational proficiency of operating members by giving them advance trainings
in order to reduce risk and increase success probability in critical mission phase.

* Operator training for special phases such as descending towards the ground surface.
* Confirming on-site actions in nominal cases in critical operations  
* Tool operators skill increase in use of tools such as GCP-NAV
* Monitoring of contingency cases and reactions  
* Operators readiness for emergencies 
* Team integration/building by JAXA and manufacturers members 
* Verification and confirmation of ground tools

1. Interface confirmation

2. Exracting areas for further improvements in tools
GCP-NAV: Ground Control Point Navigation

3. Feedback into real operation
3.1 Identification of improvements in operation manual
3.2 Brushing up of contingency plan in navigation control and guidance

GNC: Guidance Navigation and Control
