This application should help workers at a construction site who work with big gloves. Once they want to check something, it would be convenient by just shaking the phone to get the desired information instead of pushing those small keyboard buttons.

The first idea was to pickup the phone N900 by shaking it. Unfortunately, we discovered that it not possible to pick up a phone call within another application - probably because security reasons.

The other idea was to display the GPS coordinates, again by shaking the phone. However, we were coding in C, and it was really difficult to find the GPS coordinates without a change of location.

Eventually, we just display the date, and we notify to user by a beep sound. However, we can use the shaking to trigger any action.

This application is developed for the constructors who work with big gloves. Once they want to check the location during work, it would be convenient by just shaking the phone to open the GPS function instead of pushing those small keyboard.

First, the user need to choose this application. And under this application, when the user shake the phone, such as up and down, if the estimation of shake movement return true, then it will call the GPS function, and show the current location on the screen. If the user shake the phone again, and estimation of shake movement return true, it would turn off the GPS function.

Shake movement estimation ⇒ Call up GPS function ⇒ Shake movement estimation ⇒ Turn off GPS function

1.Shake movement estimation

2.Call up Date function(Encounter with unknown problem to call up the GPS function, so we use call up the Date function to instead of)

3.Shake/Touch to turn off Date function

4.Beeping function(additional Mini function)

Estimation of shake movement return false.

Call up the Date function successfully.

What we have done so far is just prototype, we could not actually achieve all what we propose in our plan but we were able to achieved shaking the mobile phone (i.e.N900)to produce a simple beep of sound and finally displace the date and time of the day to the construction workers. After experiencing the Maemo environment, we just feel that it's not such convenience as java. And also because of we do not familiar with Maemo, this brings a lot of difficulties for the programming.
