Week10

I think that self-approach will result in more access for more people because it will allow people to easily access for disable people. Overall, 12.4 per cent of Canadians reported having a disability. Now, the disability rate has climbed more than two percentage points, to 14.3 per cent.” http://www.cbc.ca/news/health/story/2009/12/28/disabled-reportcanada.html

I believe we should take more concern about people with disability and make their life easier.

Why do you need to understand human cognition in order to understand design?

I think you need to understand human cognition in order to understand design because cognition is what goes in our heads when we do daily tasks. It involves thinking, learning, daydreaming, decision making, and writing. When I am studying for my exam I need to learn the material for an exam, pay close attention, perceive and try to remember everything. Sometime when we are not sure what we are looking for we talk with people or browse on site to find out the right information.
Memory is also part of cognition that involves recalling various kinds of knowledge that allow us to act appropriately such as remember someone name, remember what we did last year. Sometime we do not remember yesterday what we did. It is not possible for us to remember everything that we see, hear, taste smell or touch.
Some of the design implications are good such as icons and graphical representation should easily tell the user what they mean.
Sounds should be audible so the users can understand they they represent.
Text should be easily readable.

Synchronous and Asynchronous

Why would a user want to use video conferencing instead of audio conferencing or text chat?

I believe I would use audio conferencing following by text chat. Audio conferencing I believe is easier because it is quick, audio conferencing is not expensive, it is easy technology to use and also can do multiple conference. Compare to video conferencing, sometime the video quality or voice is not good. Audio conferencing is easier to setup that a video conferencing, anyone can easily learn how to use audio conferencing and audio conferencing is more accessible.

For young generation prefer text message because the user can get immediate response, and if you are not able to talk out loud, you can easily text the other user, it is cheap compare with video conferencing, the user can easily text around the world,

Gesture Based Computing

What do you think of gesture based computing? Do you think it will become a widely used paradigm or is just wishful thinking?

I think gesture based computing is a really good technologies who love technologies, there are a lot of gesture based computing in the market such as Nintendo Wii, Apple iPhone and ipad. I believe Nintendo Wii is a great example of gesture based computing because it gives the user to interact with computer based technologies. Logitech and Apple have brought many gesture based to the market. It is being widely used in real life such as have iphone, ipad, and smartphone. While searching on internet more about gesture based computing I came across this video that describe how gesture based computing can be used just using hand.
