Rapid Prototyping of Ubiquitous Computing Applications: Tools & Frameworks


Google Tech Talks March, 24 2008 ABSTRACT Yang Li – RESEARCH SCIENTIST Pervasive or ubiquitous computing (ubicomp) applications can support people’s everyday activities in the physical world by leveraging advances in sensor technologies and computing infrastructures. Designing ubicomp applications is challenging because our everyday activities are more complex, dynamic and less structured than the tasks supported by traditional desktop computing. Ubicomp design is difficult, time-consuming, and requires a high level of technical expertise, especially with sensor technologies. To address this, I created a set of rapid prototyping tools and frameworks. My early work with Topiary introduces high-level abstractions, such as maps and scenarios, for designers to easily model location contexts and specify location-based behaviors. Topiary also allows a design to be tested in the field via a Wizard of Oz approach, without deploying a location sensor infrastructure. My recent work is focused on activity-based ubicomp prototyping, a process for enabling long-term activities (such as keeping fit)—a larger unit for design than the tasks that are the focus of traditional design. To support such a process, I created ActivityDesigner, a system that allows designers to create functional prototypes of ubicomp applications based on field observations, and easily deploy and test these prototypes in situ.

I want to become a reverse engineer & an ethical hacker, what courses and degrees Should I have to attain ?

as my question tells itself what is my aim of life (Full knowledge in ethical hacking & softwares specially & avoid Hardware please) . I want perfect suggestions from all of you. What should I do After Diploma In Computer science engineering to get SECURITY + CERTIFICATION. Also suggestions for studying outside INDIA are most welcome.

Homemade 3D Printer at work printing a head.


HI, This is my homemade 3D printer at work. This is the head of Walt Disney. It was awesome… and freaky… to see the head being created by the printer. The material is ABS plastic and it took 2h45min to print. There are some imperfections but…hey..this device is a fraction of the cost of the ‘big’ machines. The design is based on the makerbot open source project. Kudos to the team!!! Let me know if you are interested and i will build you one :) Thanks, Eddy
