launching a new blog

hello everybody this is my first ever blog.....just have a look if like it...just join it.......and share any technological related topics......thank you!!!

in reference to: ideas for future (view on Google Sidewiki)

out of the box!!!!!!!

Google toolbar and side-wiki are matchless.......
awesome work by Google!

Every ones favourite: CLOUD COMPUTING!!!!!! Letz check how SAFE is it.

An issue with cloud computing services is that, despite the numerous protections built in to a cloud service itself, any account is only as secure as the password used to access it. A recent example of consequences of insecure password was seen. A micro-blogging service had their online accounts accessed by hacker and numerous sensitive corporate corporate documents stolen. The documents were housed in a search engine's company's online web office service. Although that company was not to blame for the brake-in, the hack may not have ever occurred in the first place if the documents were hosted securely on-site, behind the firewall. Instead, the entire company data was only one password crack away from discovery. The details of this issue are highly technical, but fascinating, and the end result is that the very nature of virtual computing itself makes hacking simpler because it allows attackers to more easily guess the numbers used to generate the encryption keys.
NOTE: Here I assumed that the reader knows about cloud computing and micro-blogging if not just google it or search o Wikipedia, or i will choose it as a next topic of discussion. Suggestions are most welcome.
Thank you!  

Gesture Recognition (part 1)

Gesture recognition can be seen as a way for computers to begin to understand human body language, thus building a richer bridge between machines and humans than primitive text user interface or even GUIs (graphical user interfaces), which still limit the majority of input to keyboard and mouse.
Gesture recognition enables humans to interface with the machine and interact naturally without any mechanical devices. Using the concept of gesture recognition, it is possible to point a finger at the computer screen so that the cursor will move accordingly. This could potentially make conventional input device such as mouse, keyboards and even touch-screens redundant.
Gesture recognition can be conducted with techniques from computer-vision and image processing.
INPUT DEVICES:

• Depth-aware cameras. Using specialized cameras such as time of flight cameras, one can generate a depth map of what is being seen through the camera at a short range, and use this data to approximate a 3d representation of what is being seen. These can be effective for detection of hand gestures due to their short range capabilities.
• stereo cameras. Using two cameras whose relations to one another are known, a 3d representation can be approximated by the output of the cameras. To get the cameras' relations, one can use a positioning reference such as a lexian-stripe or infrared emitters.
• Controller-based gestures. These controllers act as an extension of the body so that when gestures are performed, some of their motion can be conveniently captured by software. mouse gestures are one such example, where the motion of the mouse is correlated to a symbol being drawn by a person's hand, as is the wii remote, which can study changes in acceleration over time to represent gestures^.
• Single camera. A normal camera can be used for gesture recognition where the resources/environment would not be convenient for other forms of image-based recognition. Although not necessarily as effective as stereo or depth aware cameras, using a single camera allows a greater possibility of accessibility to a wider audience. 

In next part we will see the challenges and solution to these hurdles also the new invention occurred in this field.

ideas for future: welcome to all!!!

this is my newly launched blog, hope you enjoy surfing on this. 
this blog is made to share the ideas everyone have in their mind,and to discuss those topics in detail and with comprehension.such exchange of ideas may reach to the conclusion and decide the feasibility of those thoughts.i explicitly want to mention that everyone is free to share their thoughts especially in the field of environment,information technology, telecommunication,computers,biotechnology, aeronautics, ,chemical engg. etc). hence i appeal to all to join this blog and just try to make our world more beautiful and comfortable. suggestions are welcome thank you!
