Vision simulator- How do things look to people with colorblindness or cataracts?

Have you ever wondered how do things look to those with colorblindness? There is a flash program that allows a person without colorblind defect to view things through the eyes of those with colorblind.

And if you are colorblind, two pictures will look similar to you, but not the same. This is due to the fact that in order to simulate colorblindness for the normal vision people, certain colors from the normal photo has to be digitally altered to the effect.

In other words, for normal vision people, "normal" photo is the full color photo. Each "colorblind" photo is associated with color deficiency as associated with the colorblind people. To stimulate the deficiency effect for normal vision people, the corresponding color has to be altered from the "normal" photo.

For colorblind people, you will get a much vibrant "normal" photo when compared to the one that is associated with your color deficiency. This is because the color deficiency photo loses some of the color that you cannot associate with, rendering it less vibrant.

YouTube URL tricks - Bypass YouTube Regional Filter

I came across this useful tricks from MakeUseOf.com to help you to fully utilize YouTube features on your website/blogs etc

The most important tips is probably the trick to bypass the restriction on watching certain clips on YouTube due to regional copyright issues. Fortunately there is a way to bypass the regional filtering! Check out trick 6!

=======================================
As from MakeUseOf article on 10 Youtube URL Tricks:

1. Embed Higher Quality Videos

To embed high quality Youtube videos, append “&ap=%2526fmt%3D18″ or “&ap=%2526fmt%3D22″ to the embed url where (fmt 18 = stereo, 480x270 resolution, fmt 22 = stereo, 1280x720 resolution)

2. Cut the chase and link to the interesting part

To link a Youtube video to the exciting part when action starts at XX mins and YY secs, you need to add #t=XXmYYs to the end of the URL.

3. Hide the search box

To hide the search box which appears when your mouse hovers over the embedded video, add "&showsearch=0" to the embed url.

4. Embed only a part of Video

If you want to skip the first YY secs of a Youtube video, you can just append &start=YY. For example, to skip first 10 secs of a clip, add &start=10 to the url.

5. Autoplay an embedded video

To add autoplay function to the embedded Youtube video so that it starts automatically, just append "&autoplay=1" to the embed url.

6. Bypass Youtube Regional Filtering

Due to copyright issues, Youtube detects your location from your IP Address and then determines if you have the rights to access to the video. If you are denied access to certain Youtube videos due the restriction, you can just change the url from http://www.youtube.com/watch?v= to http://www.youtube.com/v/ to bypass it.

7. Download Video

If you want to download a video from Youtube but don't want to install softwares to do it, you can just replace the URL of the video from Youtube to KickYoutube to get to kickyoutube.com. It has all the options that you can choose from to download the video.

=======================================

Head over to MakeUseOf comment section to learn more about the tips!

A2DP (Stereo Bluetooth) on Win XP/Vista -2


From my previous post on getting A2DP (Stereo Bluetooth) on Win XP/Vista, there is another popular software called BlueSoleil that you can use.

However, I prefer the Toshiba bluetooth stack due to the fact that BlueSoleil does not seem to have the option to change A2DP streaming quality.

However, BlueSoleil is very user-friendly in terms of getting your Bluetooth equipment paired up. However, BlueSoleil is not free. The trial version of the software has plenty of limitations. If you are very good in web searching, there are copies of full version floating around for you to download for free. *Hint: torrent sites

As an example, sometimes your built-in laptop Bluetooth adapter or Bluetooth USB dongle does not have the capability to support the high bandwidth required for high quality stereo bluetooth (A2DP). When it happens, the sound will be "cut-off" for a moment every few seconds/minutes to the point of my frustration.

With the Toshiba bluetooth stack, you have the option to change audio quality. To do so, you must have paired the A2DP-capable headphone. Then.

1) Go to Bluetooth Settings
2) Right click the icon of your paired A2DP headphone and choose Detail
3) Under Setting, you can choose a four options (Auto, High Quality, Standard, Low Quality) for Sound Quality

The default setting is Auto. If your A2DP audio skips, you can try changing the quality level to Standard and the skipping should go away.
