Stantum’s High Precision Multitouch

We love keeping track of new interaction technologies and this new touchscreen by Stantum looks especially promising. Engadget shot a hands-on video with it at the Mobile World Conference. It’s a resistive screen, so it can be used with both fingers and styluses (unlike capacitive screens). It’s sensitive enough that you could use a brush too. The screen supports any number of multitouch points and does pressure sensing based on the size of the detected fingertip. The touch detection is actually more accurate than the screen can display. Stantum is hoping mobile manufactures will pick up their input framework for inclusion in new devices. The resistive touchscreen was built to Stantum’s specifications (it won’t work with current phones), but they say it wouldn’t be hard to go into mass production.

Segway And Input Filtering

[Kerry] is building a segway type vehicle for a senior project. Though it doesn’t appear to be done yet, there is some good work finished. As with any balancing bot, it relies heavily on input from a gyroscope, and at least in this case, an accelerometer. That data can be very messy. The sensitivity of the sensor means that people often end up with vibrating or drifting in their projects. [Kerry] has put some work into finding a method of smoothing that results in fast, accurate, but smooth reaction. You can see a video of some comparisons between methods after the break.

Bristle Bot Controversy

When the Bristlebots were released back in 2007 by Evil Mad Scientist Laboratories, we all thought they were pretty cool. Apparently someone at Klutz did too. They have released a book, with the title “Invasion of the BristleBots”. The bots seem to be identical and the name is identical. There is no mention of Evil Mad Scientist Laboratories anywhere in it. [Phillip Torrone] has attempted to contact Klutz and the book publisher Scholastic directly to find out more information.

[Windell] and [Lenore] from EMSL had this to say:

“This is the first that I’ve heard of it. Frankly, I am a bit offended. Klutz makes some nice things, and I’m surprised that they wouldn’t have contacted us, asked permission, or at least given us credit. (Locomotion by ratcheting bristles isn’t remotely new — it occurs in nature — but the name ‘Bristlebot’ is surely ours, and I don’t know of any prior implementation with a toothbrush.)”

You probably know EMSL from their other projects such as the Peggy and Meggy jr. How would you feel if a project you did was published without credit? Would you care or not?
