One of the most interesting technologies emerging in the area of consuming services has to do with robotics. Currently, there are a number of cases where robots are used to serve people in specific situations. Such an example is a company based in South Korea named KIST has led the development of a humanoid teaching robot called Erki, which has been under trial for more than a year now as an assistant in primary school teaching. Using robots as assistants in public places can be quite challenging. There are a number of issues to take under account apart from the interface and the communication of the robot with humans. For example, how will the robot operate in a situation where a group of students try to vandalize it, what happens when a part of the robot breaks down, how often and how long does it need to be recharged?

This year’s blog action day is dedicated to the power of WE. Given this bolg’s focus on accessibility I can see many ways that we can help for accessibility. Sometimes even without knowing about it. The story of CAPTCHA and reCAPTCHA that follows is just an example of such a case.
CAPTCHA which is an abbreviation for Completely Automated Public Turing Test To Tell Computers and Humans Apart is something that most of us have come across in our web browsing.

How could a blind person see and understand what is written in an image which doesn’t have and alternative text? How could a persons with dyslexia and other print disabilities use them?

While waiting for the next monday post I’d like to turn your attention to a couple of interesting sources/articles that I’ve recently discovered.
The first is an article in ReadWriteWeb which explains how the Boomers generation is going to play a significant role in new technologies and their adoption in the future since in the US alone it is predicted to reach over 50% of the population until 2030. One might think… “and what this story tells us about accessibility?”. Well at first sight you might not realize that the buying power of that population will force markets to think about them more seriously. Read the rest of this entry »
This week we are revisiting once again education. We already talked about collaborative learning and how ICT helps in that process in a previous post.
Another interesting trend in CSCL is the use of virtual worlds and gaming. Currently, there is a variety of applications on the web offering educational virtual worlds for kids that require children to complete projects and tasks, play games and throughout this process learn a variety of subjects.
