Mordo wears the Vaulting Boots of Valtor throughout the movie and first demonstrates their use to Dr. Strange when they are sparring. The Boots allow the user to walk, run, or jump on air as if it were solid ground.
When activated, the sole of each boot creates a circular field of force in anticipation of a footfall in midair, as if creating free-floating stepping stones.
How might this work as tech?
The main interaction design challenge is how the wearer indicates where he wants a stepping-stone to appear. The best solution is to let Mordo’s footfall location and motion inform the boots when and where he expects there to be a solid surface. (Anyone who has stumbled while misjudging the height or location of a step on a stairway knows how differently you treat a step where you expect there to be solid footing.)
If this were a technological device, sensors within the boots would retain a detailed history of the wearer’s stride for all possible speeds and distances of movement. The boots would detect muscle tension and flexion combined with the owner’s direction and velocity to accurately predict the placement of each step and then insert an appropriately elevated and angled stepping stone. The boots would know the difference between each of these styles of movement, walking, running, and sprinting and behave accordingly.
As a result, Mordo could always remain upright and stable regardless of his intended direction or how high he had climbed. And while Mordo may be a sorcerer with exceptional physical training, he isn’t superhuman. With the power of the boots he is only able to run and step as high as he could normally if for example he was taking a set of stairs two or three at a time.
As a magical device, the intelligence imbued in the boots is limited to the awareness of the intent of the sorcerer and knows where to place each force-field stepping-stone.
Hover technology is a thing in 2015(1985) and it appears many places.
When Marty has troubles with Griff Tannan he borrows a young girl’s hover scooter and breaks off its handlebar. Hes able to put his skateboarding skills to use on the resulting hover board.
Griff and his gang chases Marty on their own hover boards. Griffs has a top of the line hover board labeled a Pit Bull. Though Marty clearly has to manually supply forward momentum to his, Griffs has miniature swivel-mount jet engines that (seem to) respond to the way he shifts his weight on the board.
George requires traction for a back problem, but this doesn’t ground him. A hover device clamps his ankles in place and responds to foot motions to move him around.
Hover tech is ideal for leaning control, like what controls a Segway. That’s just what seems to be working in the hoverboard and hovertraction devices. Lean in the direction you wish to travel, just like walking. No modality, just new skills to learn.
So this is going to take a few posts. You see, the next interface that appears in The Avengers is a video conference between Tony Stark in his Iron Man supersuit and his partner in romance and business, Pepper Potts, about switching Stark Tower from the electrical grid to their independent power source. Here’s what a still from the scene looks like.
So on the surface of this scene, it’s a communications interface.
But that chat exists inside of an interface with a conceptual and interaction framework that has been laid down since the original Iron Man movie in 2008, and built upon with each sequel, one in 2010 and one in 2013. (With rumors aplenty for a fourth one…sometime.)
So to review the video chat, I first have to talk about the whole interface, and that has about 6 hours of prologue occurring across 4 years of cinema informing it. So let’s start, as I do with almost every interface, simply by describing it and its components. Continue reading →
Several times throughout the movie, Loki uses places the point of the glaive on a victim’s chest near their heart, and a blue fog passes from the stone to infect them: an electric blackness creeps upward along their skin from their chest until it reaches their eyes, which turn fully black for a moment before becoming the same ice blue of the glaive’s stone, and we see that the victim is now enthralled into Loki’s servitude.
The second interface David has to monitor those in hypersleep is the Neuro-Visor, a helmet that lets him perceive their dreams. The helmet is round, solid, and white. The visor itself is yellow and back-lit. The yellow is the same greenish-yellow underneath the hypersleep beds and clearly establishes the connection between the devices to a new user. When we see David’s view from inside the visor, it is a cinematic, fully-immersive 3D projection of events in her dreams, that is presented in the “spot elevations” style that is predominant throughout the film (more on this display technique later).
Later in the movie we see David using this same helmet to communicate with Weyland who is in a hypersleep chamber, but Weyland is somehow conscious enough to have a back-and-forth dialogue with David. We don’t see either David’s for Weyland’s perspective in the scene.
As an interface, the helmet seems straightforward. He has one Neuro-Visor for all the hypersleep chambers, and to pair the device to a particular one, he simply touches the surface of the chamber near the hyper sleeper’s head. Cyan interface elements on that translucent interface confirm the touch and presumably allow some degree of control of the visuals. To turn the Neuro-Visor off, he simply removes it from his head. These are simple and intuitive gestures that makes the Neuro-Visor one of the best and most elegantly designed interfaces in the movie.
