CogTool 1.1.3

CogTool... Designers want to know how users will interact with their systems, but they often do not have the time or resources to test their designs with actual users. This is especially true for systems intended for trained users. It can be expensive to train users with a prototype, but unskilled users do not interact with a product in the same way as a skilled user. Cognitive performance modeling aims to solve this problem by predicting how a skilled user will interact with a system. Simulation and analysis take the place of expensive training and testing.

Predictive human performance modeling has one of the longest research histories in Human-Computer Interaction. Starting with Card, Moran, and Newell in the 1980s, the prediction of skilled performance time has enjoyed a constant stream of validation and expansion into many areas of user interaction with computers. Over one hundred research papers have been published about GOMS and the Keystroke-Level Model (KLM). Given its validity and predictive value, it is surprising that modeling has not become widespread as a tool for design in the user experience community. Our belief is that the cost of learning and constructing correct models, even ones as simple as the KLM, is perceived to be too high to justify the benefits of estimating skilled performance times.

We don't believe that this has to be true. With the support of tools, the time and training costs of performance modeling can be greatly reduced, and the accuracy of resulting models can be increased. Our project has produced a software application that takes the first steps toward these goals. We have already achieved great reductions in the time to produce new KLM-GOMS models. We have also shown an improvement in the accuracy of predictions compared to previously published examples of KLM.

Detailed information is provided in the CogTool User Guide. We highly recommend that you read this guide to get the most out of the CogTool system.

To help you get started quickly with CogTool, we have also provided a Tutorial. This document walks you through an example in detail, but it is not as comprehensive as the CogTool User Guide and it refers to the CogTool User Guide, so you need both.

The ability to execute task models integrated with driving is not available in the current version. If your primary interest is models integrated with driving, you may still use the old version, which requires a Mac OS X system (but does not run on Intel Macs).

suraj.sun tips a report up at CNet which begins: "Browser makers, grappling with outmoded technology and a vision to rebuild the Web as a foundation for applications, have begun converging on a seemingly basic but very important element of cloud computing. That ability is called local storage, and the new mechanism is called Indexed DB. Indexed DB, proposed by Oracle and initially called WebSimpleDB, is largely just a prototype at this stage, not something Web programmers can use yet. But already it's won endorsements from Microsoft, Mozilla, and Google, and together, Internet Explorer, Firefox, and Chrome account for more than 90 percent of the usage on the Net today. 'Indexed DB is interesting to both Firefox and Microsoft, so if we get to the point where we prototype it and want to ship it, it will have very wide availability,' said Chris Blizzard, director of evangelism for Mozilla. ... Microsoft publicly endorsed Indexed DB on its IE blog: 'Together with Mozilla, we're excited about a new design for local storage called Indexed DB. We think this is a great solution for the Web,' said program manager Adrian Bateman."

And just like that, today we have the third photo leak of the mysterious BlackBerry slider. Unlike the first time we saw it but much like the second, the device has been placed next to a Curve 8900 for the sake of a size comparison. On its side the slider is noticeably thicker than the 8900 , but today it has been turned on its side in order to let us know exactly how thick this sucker is. What this device is actually called is anyone’s guess, but the general consensus is that this is not the Storm3. So what then is it? Lately a rumor has been floating around that it is actually a Bold owing to its identical styling queues to the current Bold 9700. Adding to this rumor is a UAProf found on RIM’s website for a 9700a that lists a portrait HVGA+ display (as opposed to the Bold 9700’s landscape HVGA+ display) and this all seems rather possible. Of course dealing with prototypes things can and will change as needed, so it looks like we’re going to have to twiddle our thumbs a little while longer until some more information comes to light. Hit the jump for a pic of device’s rear sans battery cover showing off its brand new F-S1 battery.

Introduced during last PMA as well as a few days ago in Japan at CP+ 2010, the New Sony Alpha compact APS HD CMOS prototypes, is still a mystery, however, Sony Europe published a few days ago a promotional video where we can get a better understanding of the camera, since the entire video seems to has been shot with it as well as its UI...

The HMK 561 Carbon Fiber Motorbike might seem like it’s from another planet, but seeing as there’s already a prototype in place, maybe humans did come up with it after all. The HMK 561 has special electrical properties that hold power right inside the frame. Since Carbon fiber is conductive, the designers are using it to distribute power instead of wires. The power will be used to power the lights and the motors between the rims. The bike also uses the energy to turn the wheels using a counter-turning axel in lieu of gears and chains, which hopefully means less maintenance as well.

Toshiba looks like it’s doing its part to ensure that we all have little helper robots to serve us in the future. The company has come up with the prototype “Wheelie” robot, which is an indoor, autonomous, 2-wheeled robot. It looks a little like something a marriage between a Segway transporter and mini bar would produce, but as long as it’s cute, right? The aim of the robot is to help out with the daily chores, such as serving food. Currently you’ll still need to place the plates and glasses on top of the robot’s head, and it will sort out the rest. If you want to see this little robot in action, check out the video after the break.

Malgré la bataille judiciaire qui l’oppose à Apple, HTC continue dans sa politique de concurrencer le géant américain. En partenariat avec Google, HTC devrait lui aussi sortir son « tablet PC » ! Cela ferait déjà 18 mois que les deux géants collaborent sur ce projet et un premier prototype serait déjà prêt à être dévoilé. On n’en sait pas plus sur cette tablette qui visiblement tournerait sous Chrome OS, voire Android si elle est lancée en ce début d’année. À suivre…

Un iPad sous Chrome ?

Blueprint Magazine describes a very neat machine:

In a small shed on an industrial park near Pisa is a machine that can print buildings. The machine itself looks like a prototype for the automotive industry. Four columns independently support a frame with a single armature on it. Driven by CAD software installed on a dust-covered computer terminal, the armature moves just millimetres above a pile of sand, expressing a magnesium-based solution from hundreds of nozzles on its lower side. It makes four passes. The layer dries and Enrico Dini recalibrates the armature frame. The system deposits the sand and then inorganic binding ink. The exercise is repeated. The millennia-long process of laying down sedimentary rock is accelerated into a day. A building emerges. This machine could be used to construct anything. Dini wants to build a cathedral with it. Or houses on the moon.

What do you think, readers? What would you build with a giant 3D printer that lays down sticky sand?

Quand l’homme a inventé le téléphone sans fil l’humanité a fait un grand pas (dans son salon). L’histoire se renouvellera-t-elle avec le vélocipède ? Je veux dire : si l’avenir du téléphone était dans le sans fil, l’avenir du bicycle est-il dans le sans rayons ni câbles ?

C’est en tout cas ce que propose ce prototype réalisé par John Villareal, un designer installé dans le Wisconsin (USA) : un vélo sans chaîne ni câbles ni rayons dans ses roues, le tout étant remplacé par des systèmes à base de pignons à entraînement direct.

Le résultat est intéressant : ce prototype est au vélo traditionnel ce qu’une Bugatti Veyron est à la proverbiale Xantia Turbo D, un peu. Espérons juste que cela ne reste pas simplement un exercice de style et que ce genre de machine préfigure réellement ce que seront nos bicyclettes dans quelques années.
