Watch This! before continuing: (It’s an amazing video prototype that re-thinks multi-touch for the desktop.)
First Clayton, I’m incredibly impressed by this video. It shows an attention to detail in production value, theoretical analysis, and overall solutioneering that I know many can learn and be inspired by.
I have a host of questions about the video:
1. This feels overly complicated. “It feels” that way b/c it looks like (I can’t play w/ it yet, right?) a piano metaphor and at that the gestures that each finger has to be able to articulate to reach the level of expert is even more complex than that of a pianist. That being said, I just realized that most functionality is available in simple strokes and this can be a way of ramping up someone from novice to expert. I just wonder how many people will be able to make it past chopsticks.
2. I have worked in the industrial design community for quite some time now. Their reliance on tablet profile desktop screens through the use of Wacom Cintiques is quite strong. Other 3D software communities like visual effects artists, etc. are also making great use of this model. The flexibility of the the cinque to articulate between positions is the key to its success b/c it takes advantage of the reality that there are different modes of operation throughout the day. I do Alias and then I answer email. But my main point is that due to the this ability to transform the tablet is not permanent and thus the stress you suggest inherit in that design is not real. BUT! I also want to say that before we had computers we wrote. I mean w/ a pen and this meant looking down and such. We survived that, no? All that is to say that I would re-evaluate your critique of the tablet position, or your limited view of the tablet profile and re-examine it.
3. Who? who is this for? I think your video is trying to generalize experiences which may not be true. For example I have changed my entire mode of operation to be comopletely browser driven. Close to 80% of my daily interactions happen in the browser. This means that due to tabs I have 1 application open at a time with maybe 2 other widgets that I access from a sidebar (music & twitter). This model of interaction feels like it is an extreme case, which is why the person above who talks about music is totally perfect for this, b/c music has such a level of complexity of controls.
Further, is “window” operation/manipulation really that hard in the current model? I probably spend 80% of my time on the keyboard and 20% on the mouse, so what problem are you look at that requires such an intense shift in hardware and software models?
This is to ask plainly, “Is the problem that great or even really there at all?”
But another important point to this is that design needs to not just think about human mechanics, but needs to be situational. I love video prototypes, but I stress to anyone who tries it that video prototypes need to be situational. The narrative of human use is an imperative in making the medium be truly useful to a design process. So I would ask that a 2nd take on this video do just that. place a “real” person in the middle using this in their day to day life. Bumptop a similar attempt at desktop re-design has the same problem, while I think that Aurora by Adapative Path is a great example of changing the browser & hell the desktop too, by embedding real human narrative into their demonstrations.
4. the loss of direct manipulation feels to me to be the crux of the issue. What makes an iphone and other multi-touch systems “work” is direct manipulation. If multi-touch is just a remoted system like a mouse, then all you’ve done is change the point of gesturing and added an arguable level of complexity that is not required. to me it is direct manipulation and not gesturing where the greatest added benefit of touch comes to play and this doesn’t address this.
5. the keyboard. 1 area that is interesting is that you don’t address the transitional moments of shifting between keyboard (well we all know the keyboard is a problem in and of itself) and the “pointing device”. The simple and current elbow articulation to a single handed mouse not only is simple and the muscle memory easy to embed, but it has the added value of leaving 1 hand on the keyboard so that experts (ever play doom?) can gesture with both hands to create unique modes of operation. I.e. control and drag causes a copy.
But the real benefit of this mode of operation is that w/ one hand “always on the keyboard” you end up with increased efficiency of target acquisition b/c the moving hand can always use the reference point of the stationary hand when trying to find home keys when leaving the mouse.
6. the existing trackpad issues where not addressed. The main one being my wife’s pet peeve which is that she always looses her cursor with accidental taps by her wrists.
7. Why choose 1. Going back to my ID studio, the current set up has many devices: critique (pen direct touch), 3D mouse, keyboard and regular mouse.
Most importantly though, that putting yourself out there like this to criticism is HUGE. This is inspirational not only for what it offers directly but because it offers a point of discussion. I could have never done this level of articulation with someone to respond to as well produced as your demonstration. It has great thinking and there are real problems to address, or more importantly even if the problems aren’t great, there are still places where we can hope to do better.
My top list:
1. object management
2. ergonomic data entry
3. mental models of pervasive and transitive computing
4. form factors beyond (too wide, open, eh?)
5. self induced behavioral change through technology
Thanx Clayton for putting this out there! It is going straight in front of all my classes and my entire faculty today!
