DuoMento, improved

Forgive me, as I am but a humble interaction designer (i.e., neither a professional visual designer nor video editor) but here’s my shot at a redesigned DuoMento, taking into account everything I’d noted in the review.

  • There’s only one click for Carl to initiate this test.
  • To decrease the risk of a false positive, this interface draws from a large category of concrete, visual and visceral concepts to be sent telepathically, and displays them visually.
  • It contrasts Carl’s brainwave frequencies (smooth and controlled) with Johnny’s (spiky and chaotic).
  • It reads both the brain of the sender and the receiver for some crude images from their visual cortex. (It would be better at this stage to have the actors wear some glowing attachment near a crown to show how this information was being read.)

These changes are the sort that even in passing would help tell a more convincing narrative by being more believable, and even illustrating how not-psychic Johnny really is.

Portable brainwave detector

Barbarella-032

Through the atom transmitter Dianthus bestows several gifts on Barbarella to help her with her mission. The first of these is the “portable brainwave detector…to test for Durand-Durand’s presence.” To operate it, Barbarella must press “a contact,” (Dianthus is offscreen when he indicates the contact, but later we see her operating the leaf-like button near the wrist) and if Durand-Durand is around, the ball of lights will glow and an alarm will sound.

The device is wearable, wrapping around Barbarella’s forearm, and held in place by a ring. This aspect of the design is good, since it means the device is ever-present for operation, and the design of it makes it lovely enough to be overlooked as a fashion accessory. In fact many characters see her wearing it and make no mention.

Manual activation is less than ideal, though, since this might tip off the suspect. This is especially true with the blinking, glowing ball of light and audio feedback. And, in fact, this is what happens later in the film when Durand-Durand trips over the device. The blinking light and audio catch his attention, betray the device for what it is, and blow Barbarella’’s cover in the process.

Portable Brainwave Device

The best feedback would be invisible, like a haptic vibration through the cuff to her skin. Ideally, the device would be constantly on, to detect the subject passively, the moment he came into range. But presuming battery life is the issue, the activation cue should be something much more subtle, like Barbarella’s touching the back of the ring with the thumb of the same hand. Such a gesture would match the existing design of the object, be discreet to an observer, and yet still discrete enough to prevent accidental activation.
