This staff appears to be made of wood and is approximately a meter long when in its normal form. When activated by Mordo it has several powers. With a strong pull on both ends, the staff expands into a jointed energy nunchaku. It can also extend to an even greater length like a bullwhip. When it impacts a solid object such as a floor, it seems to release a crack of loud energy. Too bad we only ever see it in demo mode.
How might this work as technology?
The staff is composed of concentric rings within rings of material similar to a collapsing travel cup. This allows the device to expand and contract in length. The handle would likely contain the artificial intelligence and a power source that activates when Mordo gives it a gestural command, or if we’re thinking far future, a mental one. There might also be an additional control for energy discharge.
In the movie, sadly, Mordo does not use the Staff to its best effect, especially when Kaecilius returns to the New York sanctum. Mordo could easily disrupt the spell being cast by the disciples using the staff like a whip, but instead he leaps off the balcony to physically attack them. Dude, you’re the franchise’s next Big Bad? But let’s put down the character’s missteps to look at the interface.
Mode switching and inline meta-signals
Any time you design a thing with modes, you have to design the state changes between those modes. Let’s look at how Mordo moves between staff, nunchaku, and whip in this short demonstration scene. Continue reading →
After ditching Chewie, Boba Fett heads to a public video phone to make a quick report to his boss who turns out to be…Darth Vader (this was a time long before the Expanded Universe/Legends, so there was really only one villain to choose from).
To make the call, he approaches an alcove off an alley. The alcove has a screen with an orange bezel, and a small panel below it with a 12-key number panel to the left, a speaker, and a vertical slot. Below that is a set of three phone books. For our young readers, phone books are an ancient technology in which telephone numbers were printed in massive books, and copies kept at every public phone for reference by a caller.
After fleeing the Yakuza in the hotel, Johnny arrives in the Free City of Newark, and has to go through immigration control. This process appears to be entirely automated, starting with an electronic passport reader.
Biff(2015) pays for his taxi ride to the McFly household with his thumbprint. When the ride ends, a synthesized voice gives the price one-seven-four-point-five-zero. The taxi driver presents him with a book-sized device with the price at the top on a red 7-segment LED display. Biff presses his thumb on a reader at the bottom that glows white as it scans. When the payment is verified, the thumbprint reader and the price go dark as a sound plays like a register.
For due diligence, let me restate: multimodal biometric or multifactor authentication is more secure.
To get Jennifer into her home, the police take her to the front door of her home. They place her thumb on a small circular reader by the door. Radial LEDs circle underneath her thumb for a moment as it reads. Then a red light above the reader turns off and a green light turns on. The door unlocks and a synthesized voice says, Welcome home, Jennifer!
Similarly to the Thumbdentity, a multifactor authentication would be much more secure. The McFly family is struggling, so you might expect them to have substandard technology, but that the police are using something similar casts that in doubt.
When officers Foley and Reese find the sleeping Jennifer, they thumbprint her on a wireless handheld device, and Officer Foley looks up the young girls information. Looking at the screen she retrieves Jennifer(2015)’s address and age.
Thumbprint is a fine unimodal authenticator, but much better is multimodal biometric or multifactor authenticator to be certain of identity.
Time traveling in the DeLorean is accomplished in three steps. In the first, he traveler turns on the “time circuits” using a rocking switch in the central console. Its use is detailed in the original Back to the Future, as below.
In the second, the traveler sets the target month, day, year, hour, and minute using a telephone keypad mounted vertically on the dashboard to the left, and pressing a button below stoplight-colored LEDs on the left, and then with an extra white status indicator below that before some kind of commit button at the bottom.
In the third, you get the DeLorean up to 88 miles per hour and flood the flux capacitor with 1.21 gigawatts of power.
