Idea Review

Review the concept of our classmates' mobile application project

Revision of Nokia Snake: (Eric Chiu)

It's good to be retro sometimes, and especially to appreciate those classics. Nokia Snake is one of the cell phone games that you'll never forget. By revising Nokia Snake is not only good to practice J2ME sytax but also get a better idea of game design. Another point I wanna mention that is, to wisely manipulate color in the revision could be a plus factor that enhance the playing experience; And don't forget the sound !!!


Hello Stranger-Mobile Karaoke(Shin-Yi HUANG)

Since we can talk together, why not sing together? Karaoke is a good thing to be added in mobile application since it's another kind of communication which might involve more emotional information within. Moreover, we can't talk at exact same time because otherwise we cannot clearly hear what other people are saying. But singing is different, we can sing together at the same time to create wonderful harmony!

It would be a good trial if it's combined with lyrics on the screen, background music in your ear phone, and your friend's singing from somewhere far far away...!
