The Cloak of Levitation, Part 4: Improvements

In prior posts we looked at an overview of the cloak, pondered whether it could ever work in reality (Mostly, in the far future), and whether or not the cloak could be considered agentive. (Mostly, yes.) In this last post I want to look at what improvements we might make if I was designing something akin to this for the real world.

Given its wealth of capabilities, the main complaint might be its lack of language.

A mute sidekick

It has a working theory of mind, a grasp of abstract concepts, and intention, so why does it not use language as part of a toolkit to fulfill its duties? Let’s first admit that mute sidekicks are kind of a trope at this point. Think R2D2, Silent Bob, BB8, Aladdin’s Magic Carpet (Disney), Teller, Harpo, Bernardo / Paco (admittedly obscure), Mini-me. They’re a thing.

Yes, I know she could talk to other fairies, but not to Peter.

Despite being a trope, its muteness in a combat partner is a significant impediment. Imagine its being able to say, “Hey Steve, he’s immune to the halberd. But throw that ribcage-looking thing on the wall at him, and you’ll be good.” Strange finds himself in life-or-death situations pretty much constantly, so having to disambiguate vague gestures wastes precious time that might make the difference between life and death. For, like, everyone on Earth. Continue reading

The Cloak of Levitation, Part 3: But is it agentive?

Full_coverSo I mentioned in the intro to this review that I was drawn to review Doctor Strange (with my buddy and co-reviewer Scout Addis) because the Cloak displays some interesting qualities in relation to the book I just published. Buy it, read it, review it on amazon.com, it’s awesome.

That sales pitch done, I can quickly cover the key concepts here.

  • A tool, like a hammer, is a familiar but comparatively-dumb category of thing that only responds to a user’s input. A hammer is an example. Tool has been the model of the thing we’re designing in interaction design for, oh, 60 years, but it is being mostly obviated by narrow artificial intelligence, which can be understood as automatic, assistive, or agentive.
  • Assistive technology helps its user with the task she is focused on: Drawing her attention, providing information, making suggestions, maybe helping augment her precision or force. If we think of a hammer again, an assistive might draw her attention to the best angle to strike the nail, or use an internal gyroscope to gently correct her off-angle strike.
  • Agentive technology does the task for its user. Again with the hammer, she could tell hammerbot (a physical agent, but there are virtual ones, too) what she wants hammered and how. Her instructions might be something like: Hammer a hapenny nail every decimeter along the length of this plinth. As it begins to pound away, she can then turn her attention to mixing paint or whatever.

When I first introduce people to these distinctions, I step one rung up on Wittgenstein’s Ladder and talk about products that are purely agentive or purely assistive, as if agency was a quality of the technology. (Thabks to TU prof P.J. Stappers for distinguishing these as ontological and epistemological approaches.) The Roomba, for example, is almost wholly agentive as a vacuum. It has no handle for you to grab, because it does the steering and pushing and vacuuming.

Yes, it’s a real thing you can own.

Once you get these basic ideas in your head, we can take another step up the Ladder together and clarify that agency is not necessarily a quality of the thing in the world. It’s subtler than that. It’s a mode of relationship between user and agent, one which can change over time. Sophisticated products should be able to shift their agency mode (between tool, assistant, agent, and automation) according to the intentions and wishes of their user. Hammerbot is useful, but still kind of dumb compared to its human. If there’s a particularly tricky or delicate nail to be driven, our carpenter might ask hammerbot’s assistance, but really, she’ll want to handle that delicate hammering herself.

Which brings us back to the Cloak. Continue reading

The Cloak of Levitation, Part 2: Could it ever work?

How could this work as technology instead of magic?

In the prior post I looked at the Cloak as a bit of wearable technology. Today let’s ask ourselves how possible this is in the real world.

The abilities of the Cloak listed in the first post imply a great deal of functionality: Situational awareness, lightning fast thinking, precision actuators throughout its fabric, gravity controls for itself and its wearer, goal awareness, knowledge of the world. Some of these aren’t going to happen, but some are conceivable over time.
