Portable media devices(I-Pod)
Input
1) touch screen-touch sensitive display device where it is respond to out finger motion2) voice input- where the devices can detect our voices and carry out many functions
Output
1) wireless speakers- instead of listening to music through our earphone. we can purchase speakers for the device.2) LCD monitors and screen- screen sizes from 1.5 inches to 3.5 inches.
Advantages
1) wireless speakers- sound can be heard clearer and our ears wouldn't be so painful when wearing the earphone the whole day
2)LCD monitors and screen- we can have a clearer view of images and video.
Disadvantages
1) touch screen- sometimes it is too sensitive as you only touch a bit, it will select a particular file easily although you don't mean to open that file.
2) voice input- if we're sick and our voice changes. It is not convenient to use voice input anymore. As it can only detect our similar voice.
This product is useful to me because it is very light and easy to carry it to anywhere. As the size of it is not very big, so it just need a small place to store it. Moreover, it is also very convenient as when we want to listen to music or watch a video, we just need to take out the I-pod and pluck in the earphones. Then, we can start doing our stuff. The storage capacity is also quite big, so we can store more pictures, music and video. Since the I-pod is way more smaller than the computer, so it is more convenient to bring out.
