It would have to be strong enough to withstand sharp movements and he supposes there is no other way but to stick it on tight with something, saying it is 'alien technology'. In an interview, the series creator Akira Toriyama himself wonders how scouters are attached around the ear and says he was always doubtful of it when he was drawing it. An antagonist character named Alberto has lost his right eye and wears a metal patch that somewhat resembles the scouter in appearance, and also acts like a tracking and communication device. The design of the scouters is similar to a device in Mitsuteru Yokoyama's 1956 manga Tetsujin 28-go. Toriyama also said that it would have been even more perfect if the form of location of the enemy picked up by the scouter were displayed in video, but if features up to that point were added, it would have been even more difficult to do as manga story developments go. Also, since a scouter only shows direct numbers, it does not take into account if an opponent is hiding thier power level. He made scouters break when they pick up a high battle power as showy staging for the manga saying it is really digital, which makes it impossible, but in terms of something analog, it is like how a counter that is rising at breakneck speed can not keep up and breaks down. So, with regards to Goku and the other Z Fighters, he decided that their power would change due to ki and could not be adequately measured. However, he foresaw that it would also be an inconvenience for him because if a concrete number is known, then it will be easy for the readers to tell who would win or lose. Akira Toriyama's number-one goal in coming up with the scouters was because it would be easier for the readers to understand if an opponent's strength is seen as a number.
