Pour le jeu diffusé à la télé, c'était Amiga, puis PC, puis Silicon Graphics :

https://en.wikipedia.org/wiki/Hugo_(game_show)#Behind_the_scenes :For Hugo and its similar television program projects, ITE originally developed a designated, custom-built computer hardware system called the ITE 3000 that would convert telephone signals into remotely control the characters in the game and allow the interaction of the audience and the TV action without delay. The system was based on two Amiga 3000 computers plus a new audio control system MIDI sampler, the DTMF system and some other extra hardware, and reportedly costed $100,000 to make. The ITE 3000 was later replaced by the PC-based ITE 4000, which used a real time motion capture system Animation Mask System (AMS) invented by Bjarne Sølvason (father of the ITE founder Ivan Sølvason) to transfer an actor's body/head/eye movements and facial expressions to Hugo's character on screen. The actor providing the voice of Hugo wore the helmet which contained sensors that could capture his facial expressions and translate them to the character, but all of the characters' body movements were pre-rendered. In 1996, ITE created new, 3D graphics for Hugo using Silicon Graphics machines. A new technology for real-time 3D animation of Hugo was unveiled in 2005, but was aimed only for export, specifically to Asian countries.
