Pen based input improvements

Lately we’ve been focusing on multitouch technologies, but that doesn’t mean there isn’t interesting research going on in other areas of human-computer interaction. [Johnny Lee] posted a roundup of some the work that [Gonzalo Ramos] and others have done with pen based input. The video embedded above shows how pressure can be used to increase control precision. Have a look at his post to see how pen gestures can be used for seamless workspace sharing and how pen rolling can give additional control.

That’s a very impressive demonstration. I wonder how they linked pressure to zooming in the last few image demonstrations without the benefit of the clutching mechanic used with the sliders.

I also was impressed.
Not only are the concepts great but it was a very well done presentation.

so many applications!

I’d be interested in seeing the pressure-sensitivity implemented in a normal mouse. Doesn’t seem like there’s any hack going on there though.

@Ronnie

It looks to me that pressure is measured
by the length of time that you press the
screen.

So I agree that it will work nice with a
mouse.

Wow, I have to say GREAT IDEA!

The best part is that the hardware technology is not only already available, but in wide use. All we need is software!

Good thinking. He has more good ideas ( http://www.dgp.toronto.edu/~bonzo/pubs.html ).

@happypinguin: The pen (the stylus) is pressure sensitive, like any wacom stylus-tablet combination.

@ronnie: I agree, I also would like to have a pressure sensor on my mouse. My Logitech MX Air has already acceleration sensors, so add a pressure sensor and a (absolute) location sensor, and it’s getting somewhere.

The PS2, PS3, xbox, and xbox 360 controllers have pressure-sensitive buttons. I wonder how you could use those in the same application.

Tie the buttons into mouse movement..

This is big for me. While its not a wacom, I use my tablet for alot of digital painting and graphic work. Pressure sensitivity is of up most importance when your dealing with painting because like with an actual brush, the amount of pressure you apply is relative to the wide of the stroke.

This video makes me excited like you can’t believe. :D

After see this i just say this SUPERB

that cursor is awesome. pressure sensitivity is great for painting etc, but with a cursor like this we can use pressure sensitivity for other things, great idea.
