How to unlock your smily face in iPhone

Wonder why there isn't any smiley face icons in your iPhone? Actually there is!



Don't know why iPhone in US lock the smiley face input (a.k.a. Emoji, in Japan); if you follow the instruction in this post, you'll easily get your smiley face icons!



But remember, these icons are only supported by iPhone, which means if you send a text message using smiley faces(Emoji) to someone's blackberry, it won't work! They only see a bunch of weird symbols.

Cell phone as a game controller

We've seen people using their cell phone as a remote to their iTunes, Laptop, and PowerPoint slide show, but have you seen this? This guy created an app to make his HTC Hero cell phone as a Nintendo game controller!



This cell phone application was developed under Android platform. More information here

MagneBall

This is a hardcore cellphone game!



Use arrow key to control the moving ball, hit the target and you'll win!
In later stage, watch out the land mine, don't go out of the boundary,
or you'll directly lose!

This game is skill required, and Flash player mobile phone required.
In the game development, the next step would be combined with tilt sensor(accelerometer, such as NOKIA N95)phone, to control the ball using tilting gesture.

Click to Play

have fun!

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...!

Mankind Radar

Searching for people? Waiting for friends? Looking for kid? Now you have a great tool to target your Mr. or Ms. Right, don't have to worried about missing important people.



Mankind Radar is a mobile application that allows you to exactly locate your familiar people. By using Java mobile technology, you can have a great visual interface to tell you where he is, how far is the distance, and which direction. With the help of embedded GPS in your phone, you can easily dynamically find the people you're looking for.

API
With the help of GPS and positioning technique, "Mankind Radar", this brand new mobile application is gonna refer to certain existing API(mobile application):

1. GPS connecting and data transferring protocol
2. Mobile Processing (for the Radar animation)
3. Reading contact information (to show their picture)
