Android Espresso Machine Interface - June 14th, 2010

Appresso Machine

Appresso Machine

Here is a mash-up of functions you never knew you needed. It brings a new salience to the multi-function device. Drop your Android phone into this espresso machine/speaker system and listen to your music while your coffee brews and your phone charges. Confused about where your coffee is sourced from? Don’t be. The QR codes on the coffee pods tell your phone everything it needs to know to display to you, the hapless Sal-of-today. The only thing missing is a function to tweet your behavior to your peeps

This thing makes coffee and spits out music. What more do you want? What more COULD you want? More? Alright well you’re in luck because this “Appresso” device does all that you want. It’s Android based. That means it’s amazing by itself. Then it makes coffee. Delicious coffee mmmm. It uses the Android technology to tell you info about the taste and scent of the coffee, then also reads QR-codes* from each coffee capsule, playing a specific song based on which pack you’ve scanned! My triple caffeinated cap plays Yanni in the morning.

Tapered edges show directionality best - June 12th, 2010

Representing Directed Edges

Different Ways of Representing Directed Edges

Danny Holten and Jark J. van Wijk from Eindhoven University of Technology in the Netherlands published a very cool study of the “best” way to represent directed edges in a graph.  Via information aesthetics:

Their experiments consisted of testing the different visual techniques (or combinations of the techniques), on which participants performed specific tasks in which they had to answer whether or not there were directed connection from one point to another in a randomly generated graph. Response times and accuracy were measured and analyzed. The different techniques tested were: “arrow”, “light-to-dark”, “dark-to-light”, “green-to-red”, “curved”, and “tapered”.

Don’t have time to actual read the details?  For human efficiency in finding paths, use tapered lines from wide to thin.

Sikuli replays GUI macros using computer vision - June 10th, 2010

Coming out of MIT’s CSAIL is a gui-macro-recording program, called Sikuli, that uses computer vision algorithms to replay GUI scripts. Because it doesn’t hook into anything except the screen rendering subsystem, you don’t have to know AppleScript or any other API to make it work. The computer vision algorithm is tolerant of the click-target moving around the screen and the researchers claim it is somewhat tolerant to changes in the visual appearance of the click-target as well.

It is based on Jython, and available for downloading on Mac (yeah!) and Windows. I think this is one of those programs that if you need it, you need it badly!

This is one of a series of HCI projects that are coming out now which mod the UI using the raw pixels as a guide. The other one I’ve seen recently is by James Fogarty and crew at UW called Prefab. Videos for both systems are embedded below.

Congratulations to Informatics Graduate Student Meg Cramer and Informatics Faculty Member Gillian R. Hayes on having their paper,
‘Acceptable Use in the Age of Connected Youth: How Risks, Policies, and Promises of the Future Impact Student Access to Mobile Phones and Social Media in Schools’ accepted to IEEE Pervasive Computing.

Abstract: “To fully engage pervasive computing technologies and youth as a significant area of inquiry, we must ask why mobile devices and social media applications that support educational learning objectives are much less pervasive in the classroom than in other parts of youth life. First, we discuss the potential mobile devices and social media have for learning, both from an individual skills and socialization perspective. Then we turn to the development of Acceptable Use Policies, which dictate the prescribed use of mobile devices on school campuses as a response to the risks schools face in dealing with disruptive or harmful speech. We describe some perceived risks and observed problems for educators with regard to youth online that characterize the attitudes toward pervasive technologies in formal learning settings. Finally, we close with some discussion of the way forward, toward a greater understanding of the youth experience with pervasive computing technologies and greater access to these systems and applications within the formal schooling context.”

Efficiently Scaling Up Video Annotation with Crowdsourced Marketplaces - June 7th, 2010

Congratulations to Computer Science Undergraduate Carl Vondrick, Computer Science Faculty Member Deva Ramanan and Informatics Faculty Donald J. Patterson on having their paper,
‘Efficiently Scaling Up Video Annotation with Crowdsourced Marketplaces’ accepted to ECCV-2010.

Abstract: “Accurately annotating entities in video is labor intensive and expensive. As the quantity of online video grows, traditional solutions to this task are unable to scale to meet the needs of researchers with limited budgets. Current practice provides a temporary solution by paying dedicated workers to label a fraction of the total frames and otherwise settling for linear interpolation. As budgets and scale require sparser key frames, the assumption of linearity fails and labels become inaccurate. To address this problem we have created a public framework for dividing the work of labeling video data into micro-tasks that can be completed by huge labor pools available through crowdsourced marketplaces. By extracting pixel-based features from manually labeled entities, we are able to leverage more sophisticated interpolation between keyframes to maximize performance given a budget. Finally, by validating the power of our framework on difficult, real-world data sets we demonstrate an inherent trade-off between the mix of human and cloud computing used vs. the accuracy and cost of the labeling.

Congratulations Carl, Deva and Don!

What if Your Twitter Followers Really Followed You? - June 4th, 2010

One of the major telecom companies in Japan, KDDI, released a web app called IS Parade (?) that turns your twitter account into a parade.  A parade in which your followers, follow you.  It is a fun visualization to play with.  I recorded a low-res sample below.  They also have a strangely addictive abstract interactive visualization on their product homepage, located here.

Virtual Pottery Wheel - June 3rd, 2010

Rapid prototyping or 3-D printing is a disruptive technology that is becoming more and more accessible. Writers like Bruce Sterling have explored the relationship between real and virtual objects through RFID technology and 3-D printing in many books and stories. Fast Company has reported on an installation in which visitors use a virtual pottery wheel to craft a digital model, which can then be printed out later if desired.

At the “Design by Performance” exhibition at Z33 in Belgium, Unfold, a Belgian design firm founded by Claire Warnier and Dries Verbruggen, and designer Tim Knapen installed something they call “L’Artisan Electronique” (“The Electronic Artisan). Composed of a 3-D laser scanner and a RepRap–a cheap, open-source, DIY 3-D-printer–the installation allowed visitors to craft a virtual piece of pottery. All of the pieces created by users were projected onto the wall. And each morning, a selection of the previous day’s creations were printed on the RepRap.
