A large projection image screen device having a seesaw structure for virtual reality where a chair is provided on one side of a lever and an image system is provided on the other side of the lever. Several rotation shafts are provided below the lever for up down rotation, left right rotation and front rear rotation, where when the chair and the screen are rotated up and downward, left and rightward, and front and rearward, a user on the chair views the images at the same view angle as the rotation angle of the screen through a location tracing device.

The invention relates to a system (1) for situation awareness in a combat vehicle (2), comprising a plurality of image-capturing sensors (3A-3E) configured to record image sequences showing different partial views (V.sub.A-V.sub.E) of the surroundings of the combat vehicle, and a plurality of client devices (C1-C3) wherein each is configured to show a view (V.sub.P) of the surroundings of the combat vehicle, desired by a user of the client device, on a display (D1-D3). The image-capturing sensors are configured to be connected to a network (4) and to send said image sequences over said network by means of a technique in which each image sequence sent by an image-capturing sensor can be received by a plurality of receivers, such as multicast. The client devices are also configured to be connected to said network and to receive, via said network, at least one image sequence recorded by at least one image-capturing sensor (3A-3E). Further, each client device is configured to generate, on its own, said desired view from the at least one image sequence by processing images from the at least one image sequence, and to provide for display of the desired view on said display.

A method performed by a vehicle feature evaluation system (1) for enabling evaluation of a simulated vehicle-related feature. The vehicle feature evaluation system determines (1001) in relation to a road-driven vehicle (2), with support from a tracking system (5), an orientation of a head-mounted display (4), HMD, adapted to be worn by an occupant (3) on-board the road-driven vehicle. The vehicle feature evaluation system further determines (1002) a simulated vehicle design feature to be evaluated in the road-driven vehicle. Moreover, the vehicle feature evaluation system provides (1006) in real-time to a HMD display (41) of the HMD, taking into consideration the HMD orientation, a virtual representation (7) of the simulated vehicle design feature superimposed on a real-time surrounding-showing video stream (6) derived from real-world image data (211) captured with support from one or more vehicle-attached cameras (21) adapted to capture surroundings external of the road-driven vehicle.
