There are several suggestion after watched the kickstarter video provide by pexemic interaction. One of the suggestion is about the product detect a movement of a object which user are holding are intending to control the screen, might as well it just detect human hand gesture to control the screen although it might cause another problem which is more than one hand. It is redundant to have an extra controller. Other than that, the product uses recognising human body technique to control the screen output such as when a user facing other direction it will pause the output. It is irritate if the user decided that part of the video he doesn't want to watch so he want to skip it without fast forward because might have some other people want to watch it, but when he is facing other direction like newspaper, then the product will pause the video, it is really irritating. Also, it might have a setting for user to choose whether they wanted to turn on the multi user mode or not, because there are different age group of user in a family. For example, if a family with kids, the multi user mode is not suitable because the kid might run around in the living room then the product detect some body then it split the screen to 2 or 3 or more, whenever kid run out of the product sense area, it turn back to normal screen.
Microsoft Courier
It is a good product which have lot of interesting feature that might help to reduce waste of paper. I am such a person who does not like to use paper, whenever i look at paper work i will felt sleepy and also we cannot fully utilise the paper because the content of writing are not huge, it will cause of wasting paper equivalent to wasting money. Therefore, this product would be a very good choice to solve the problem of mine but it does need time to learn how to use it because of the complexity.
Vending Machine
For example, step one, two and three can be placed align from top to bottom. The following figure is the paper prototype I create for the vending machine:
First of all, this product is having a really bad design due to the complexity and messy interface. Although it does have a instruction and step to follow, it is still too annoying because of too many button, words, icon that cause confusion. Some of the button that are not use frequently can be place at bottom part of the interface so that user will not accidentally press it. Also, the sequence of the step for adding value can be arrange nicest to make the product more easy to learn.
Above is a rough interface design that i create for the vending machine.
