  • the second recess 42 is provided with a second display (not shown), comparable to the first display 34.
  • the second display is operated in the same manner as the first display, i.e. the second display has basically a viewing position and a flush position. In the viewing position, the screen display faces a user of the second display. In the flush position, the second display is accommodated in the second recess 42, and its substantially flat back is substantially flush with the work surface 36 of the table 35.
  • the second screen display is also coupled to a drive means, e.g. an electrical actuator, for rotatably moving the second display from its flush position to its viewing position.
  • the actuator for the second display is different from the actuator 44 for the first display 34.

  • the first recess 40 accommodates the master interactive unit
  • the second recess 42 accommodates a slave interactive unit.
  • the executive person may thus take place in front of the master unit, whereas the members to a meeting take place in front of the slave unit.
  • the executive person is then able to enter data into the computer system in various ways : by touching the keys of the keyboard, by entering a card having a magnetic strip, by touching the touch screen display device 45.
  • That person and the members may also acquire data from the computer system, e.g. by reading the data displayed on the screen display device associated to the display and by listening to the speaker or speakers coupled to the display.
  • the members may enter into the computer system voice data and visual data.
  • a microphone and a video camera may be mounted in the second display.
  • the table 35 also includes a third recess 43, organised similarly to the second recess 42.
  • the third display may be rotatably moved by a third actuator, but in a preferred embodiment, the second and the third display are coupled to one single actuator for opening and closing the second and third display simultaneously.
  • a plurality of recesses may be made in a large conference table, thereby allowing to have various displays and e.g. just one master assembly.
  • control or control panels of the keyboard 48 and the control of the screen display device 45 are built in, in the lower compartment 81 of the carriage 72, underneath the data entry device 41. These control panels are preferably close to the devices they drive, since it may be necessary to keep the length of the connecting cables within strict specifications of these units. From these control panels, cables run to the interfaces for the peripheral devices. These interfaces are preferably arranged close to the central processing unit (CPU). This CPU is preferably mounted in the hardware box 21 underneath the table top 37, but the CPU along with the interface boards may be mounted in a different cabinet, e.g. standing on the floor.
