One of the most delightfully flamboyant characters in sci-fi is the radio star in The Fifth Element, Ruby Rhod. He wears a headpiece to hear his producers as well as to record his own voice. But to capture the voices of others, he has a technological staff that he carries.
The handle of the device has a microphone built into it. Because of the length of the staff, his reach to potential interviewees is extended. The literal in-your-face nature of the microphone matches Ruby’s in-your-face show.
To let interviewees know when they’re being recorded, a red light in the handle illuminates. This also lets others nearby know that the interviewee is “on air” and not to interrupt.
Ruby also has a single switch on the handle. It’s a small silver toggle. It’s likely that he can set this switch to function as he likes. The one time we see it in action, he has set it to play back an “audio cut,” (the sound clips morning radio talk show hosts insert into their programs) in this case an intimate recording of the Princess of Kodar Japhet. He flips the toggle to play the cut, and flips it back when it’s done.
Here, a different input would have worked better. The toggle switch is too easy to bump and kind of ruins the design of the handle. Better would be a billet button. This sort of momentary button sits flush with a bezel, which prevents accidental activation from, say, a finger laying across it, or resting the button against a flat surface. If Ruby wants the recorded sound to play out completely, and the button press only starts or stops the playback, it would be good to know the state of the playback, and using a billet button with a LED ring would be best.
We also know that Ruby is a performer. He would be happier if he had more than a play button, but a way to express himself. His hand is already in a grip to hold the staff, so the control should fit that—If you could outfit the billet button with directional pressure sensitivity, he could assign each direction to a control. So, for instance, while he was pressing the button, the audio would play, and the harder he pressed up, the volume for each echo would increase. Or pressing down could lower the sample in tone, etc. This would allow him to not just play the audio cut, but perform it.
To work as a device that the character would want to carry, it has to match his sense of style. I mean this first in a general sense, and the device does that, with its handle of ornately carved silver. Ruby’s necklaces, bracelets, and rings are all silver, and they work together. The staff also works in his hand like a drum major’s baton, augmenting his larger-than-life presence with an attention-commanding object.
It has to fit his daily fashion as well, and the staff does that, too. The shaft can change appearance. I don’t know if it’s an e-ink-type surface, replaceable staves, or fabric sleeves that change out, but when Ruby’s in leopard print, the staff is in leopard print, too. When Ruby’s decked out in rose-adorned tuxedo black, the staff matches.
Though this is more a portable than a wearable technology, the fact that it can change to match the personal style of the wearer makes it not only functional, but since it fits his persona, desirable as well.
