How Samsung Galaxy Tab 750 can Also Change the world

raghava — Mon, 05 Sep 2011 17:53:21 +0000

Samsung has launched their “Samsung Galaxy Tab 750” on 10th August 2011 and I missed on putting the embed for the live streaming. But here is a recorded version available and it can give more info than any other blog,

First there were room size computers, then personal computers, then laptops, then net books and now there are tablets. Technology is evolving day by day and making the life of humans much more comfortable in dealing with their day to day activities. I am writing this post to take part in the Indi blogger Samsung galaxy tab contest. I heard about IPAD which revolutionized the way people with disabilities are benefited and how many opportunities that a new technology and innovation can bring a change in every ones life.

I came across how the tablets are helping people with disabilities in different ways and started to read more success stories of using tablets. Then I started researching how blind people are using android platform tablets and I haven’t found any relevant results through Google which can help me. That amazed me and thought to look for a screen reader for android platform and I haven’t found a solution till date. I am still researching about how people with visual impairment can use the Android based Tablets. I am sure there will be some application developed to address this problem and if it is meeting the needs of people with visual impairment Samsung galaxy tablet might be a hit in the community. A lot of technology innovations doesn’t concentrate on the Differently Baled communities because they think there is no money in this sector, but that is not true there is a huge amount of potential and business opportunities in the world of accessibility and assistive technology.

If Ipad can create history, I am sure Samsung galaxy tab can also create history with more powerful features than IPAD and here there is no limitations attached as the operating system is open source and any one can create applications without limiting their creativity and imaginations.

If Samsung can enable the channels to get information about how people with disabilities can use their products efficiently I am sure there will be a huge market which they never thought to tap.

5 reasons why I would prefer Samsung galaxy tablet

1. open source- Samsung Galaxy tab runs on a open source operating system Honey Comb which will enable better accessibility features and will have ability to make all the necessary applications according to my needs. I haven’t worked with any Tablet computer till date but I am sure Open source technology will open new doors like how “NVDA” for windows a open source screen reader has enabled jobs for a lot of visually impaired.
2. i had an opportunity to play with a Samsung galaxy tablet few weeks back when I was having a meeting with my friend lakshmi Rebecca and I found it is very sleek, light weighted, easy to carry etc. This helps me to carry the tablet where ever I go and can let the world know that my disability has not limited me in any way.

3. With my low vision problem I often find it difficult to watch videos and images going close to my computer monitor. With this tablet this problem can be over come as there will not be any kind of extra stress on my neck and as I can bring tablet very close , change angles I will have a better view of the pictures.

4. i like designs a lot and I often find it difficult to find some one who can explain how a particular design looks so that I can imagine. Every time I cannot call my family or friends to come near my laptop or desktop to explain, but now I can carry my tablet to my family or friends who can explain them.

5. This tablet can help me to take notes more effectively as it is easy to carry than a laptop and often people with visual impairment find it difficult with note taking if there is no proper facility to arrange their laptop and belongings.

I can come up many ways of how visually impaired can use the Samsung galaxy tab, but the question for me is which screen reader works with the Honey Comb Android platform?

Samsung is one of the leading brands which brought Android based phones and Tablets in to the Indian market and let us see the specifications how this tablet is different from others,

I got these details from the various sources of the web and I have no clue what most of the specifications are for. I have been a tech enthusiast and was attached to the computer world since 2004 but my goal has always been how I can enable and use the technology to fight against the limitations which my disability created. 50 yrs of policies has not changed anything in lifes of people with disability, but a revolution which took in technology in last 10yrs has changed everything. Today I work only because computers are accessible with the help of a screen reader and I found this article how Ipad is helping people with disabilities.

graphene word press theme review

raghava — Tue, 15 Mar 2011 03:44:58 +0000

I always wanted to keep a good looking theme for my blog’s and due to my visual challenges i was unable to stick to any one theme. I moved to couple of themes and finally settled on Inove word press theme till yesterday. couple of day’s back i landed on some random blog through twitter and came to know about Graphene theme. with help of my low vision and my big monitor i found that this theme is very impressive and has got all that features that i require. First i thought to purchase either studiopress or any other paid theme, but this free theme gave all the features that i require.

I immediately plugged the theme yesterday and started to play around with it’s built in features. With out much of effort i was able to integrate my Google adsense between posts and all the options of Grapheme WP theme are outstanding. i don’t know if there is any other theme which can offer so many features, simple to use with clean usuability which is free.. i haven’t really done much research on themes but this one caught my eye and i feel graphene will be used widely.

A special thanks to khairul-syahir, developer of this theme and this theme is accessible for screen reader’s too. Accessibility is one of the main concerns with which I am stuck when I thought to move to life style or any other theme.

If you all know any other theme which has got awesome features and is free to use do let me know here in the comments area. I am going to come up with couple of more blogs soon and I would love to try them out.

Mobile Apps – the next big trend

raghava — Wed, 12 May 2010 04:32:12 +0000

Thanks to the Appstores, mobile apps market have exploded in the last few years.
According to some reports the appstores are going to be as big or bigger than the internet. Industry analyst Chetan Sharma in his report on “Sizing Global Apps Market‟ suggests that .the overall mobile apps downloads are expected to increase from over 7 billion in 2009 to almost 50 billion by 2012 growing at the rate of 92% CAGR. The revenue from mobile apps which includes both paid downloads and revenue from advertising and virtual goods is expected to increase from $4.1 billion in 2009 to $17.5 billion by 2012 at the rate of 62% CAGR.
India also has seen several major players launch appstore. Among the operators Aircel, Airtel, Vodafone and Reliance have announced their appstores early this year. From the device side ecosystem Nokia, Samsung, Intel have also launched their appstore. It is quite evident that the mobile apps market has indeed become quite sizable and only going to expand with an accelerating pace.
So it is only very timely that Numo solutions bring a first of its kind event called AppJam which will showcase the best of mobile apps in the region. It will have an eminent Jury and a clued-in audience vote for the best app . Think of this is reality shows such as Indian Idol/Sare Ga Ma/Dance India Dance meets technology conference/events.  (albeit not entirely) . The jury award will be decided by a jury on several factors and winners will be chosen. The audience present will vote through their phones to select Audience winner. Experts will share learning‟s on marketing and monetizing apps.

Mobile apps present significant opportunities in both the global and local markets. According to Preethi Raj, Manager Developer Marketing APAC Intel “With the Intel® Atom™ Developer Program, we are providing developers a great opportunity to create and monetize their innovative applications for Intel® Atom™ based devices while creating compelling new experiences for users. In less than six months, the program has a registered base of 15000 developers. According to ABI research on Netbooks – Q1 2010, 35M Intel® Atom™ based netbooks were shipped in 2009 and number is expected to grow to 154M by 2014. Also as Intel® Atom™ extends into other devices like handhelds, in-vehicle infotainment devices, and connected TVs developers can write one software application to run on multiple devices. ”
AppJam is designed to delve in details of critical aspects such as marketing and business models of apps which are most vital for success in the market . The Demo showcase presents an unique platform for Indian apps to rise to the forefront both globally and locally

I am attending this event on May 15 and request all mobile developers, students, innovators to submit their mobile application and get their apps reviewed by the industry experts.

protect your blog from spam comments

raghava — Tue, 23 Feb 2010 13:41:46 +0000

As always spammers find a way of spamming your blog by commenting with lots of irrelavent and unwanted stuff. How do you deal with these kind of comment spamming. If you are on wordpress like me you might have installed Akismit, but inspite of installing such a powerful spam filtering system spammers are trying to find a way to break in.
I thought I will use a captcha which will reduce and stop automatic commenting tools to work I came across a wonderful tool called recaptcha. When I was going through Jerry West blog of seo revolution I came across this wonderful captcha system and this works perfectly.

Captcha is a technology where it can determine whether the visitor who is commenting on our blog is a real human or a bot. These bots have ability to do thousands of posts with in a short time. Some time if we neglect these comments we will drop our search rankings too rapidly. Captcha gives the human a challenge of typing a word and decides if the comment is done by a human or not. Bots don’t have ability to read graphical interface and they cannot crack these digital captcha systems.

You can see the demo on my blog now and this technology is being used by google and the good part of this is it’s owned by google. It’s easy to setup, manage and I recommend this for any blog owner. You can find recaptcha here.
