N900 play next music track when you shake the phone (python script)

Hi,

I've made a simple python script to skip to the next track when you shake the phone :D

heres what you have to do:
extract the script to your phone
open the media player and start playing music

open the terminal and:
cd to the directory of the script
type in:
python skipshake.py

shake the phone and see the results :)
when you're done with the script close the terminal.

here is the script:

Code:

import gobject

import dbus

import dbus.glib

import pygtk

import gtk, math, os, time

from dbus.mainloop.glib import DBusGMainLoop

class Table:

        def __init__(self):

                dbus_loop = DBusGMainLoop()

                self.bus = dbus.SystemBus(mainloop=dbus_loop)

                go=0

                margin = 500

                while True :

                        rawMceRequest = self.bus.get_object("com.nokia.mce", "/com/nokia/mce/request")

                        self.mceRequest = dbus.Interface(rawMceRequest, dbus_interface="com.nokia.mce.request")

                        orientation, standState, faceState, xAxis, yAxis, zAxis = self.mceRequest.get_device_orientation()

                        if go==1:

                                if abs(current) > abs(yAxis)+margin:

                                        self.roger(abs(yAxis))                        

                        current=yAxis

                        time.sleep(.25)

                        go=1

        def roger(self,a):

                i=0

                shake_list=range(100)                

                print "+-+-+-+-+-+-"                

                while i<100:

                        orientation, standState, faceState, xAxis, yAxis, zAxis = self.mceRequest.get_device_orientation()

                        shake_list[i]=(int(yAxis))

                        i+=1

                z=sorted(shake_list)

                slope= [y - x for x, y in zip(z[:-1], z[1:])]

                print"current slope (",sum(slope)/99,")"

                if sum(slope)/100 > 35:

                        os.popen("dbus-send --dest=com.nokia.mafw.renderer.Mafw-Gst-Renderer-Plugin.gstrenderer /com/nokia/mafw/renderer/gstrenderer com.nokia.mafw.renderer.next")

                        print "skipped track at a slope of",sum(slope)/99

def main():

        gtk.main()

        return 0       

if __name__ == "__main__":

    Table()

    main()

please test it out and tell me what you think about it

Haven't tried this (or the other), but check out shake2control.

hey :)

I've seen that one, but it is in C and it is a bit more complex than this python script.

cheers :D

Re: N900 play next music track when you shake the phone (python script)

Does this check the prox sensor for being covered before skipping the track (I am no expert in python but didnt see anything suggesting it did). I prefer if it doesnt since I keep my n900 in its case most times.

well I made this script so I can change the track even if it is inside the n900 cover, say I'm transmitting a FM station to my car, I don't want to take it outside the cover to get it working,

also this script is pretty smart when it gets to shaking the phone, I didn't encounter any random track changes yet :)

try it out and tell me what you think.

Groovy - Getting the pgone out of its case to go to the next track was always a potential crash hazard for me :) Will check the script and let you know.

Re: N900 play next music track when you shake the phone (python script)

hmm doesn't seem to work for me. it just displays changes in slope level when i move and shake the N900.

Yeah same with me! just echoes some slope

yea it should show you a slope, but it won't change the track if the slope is less than 35, you can change that from the script.

to get a higher slope you'll need to be shaking it for a bit longer
if you change the setting of the slope to a lower value, it'll change the track if you shake it less. but 35 is the best value I came up with since it makes sure you've shaken it enough.

if you get the message:
skipped track at a slope of some_number
that means that the player should've skipped the track

if it did display "skipped track at a slope of some_number" but didn't change the track, then please tell me so.

feel free to explore the script and play with it as much as you want

cheers ^^

Re: N900 play next music track when you shake the phone (python script)

To make things clearer about the slopes, I've collected some data from previous shakes and plotted them with pygame
here you go :D

Re: N900 play next music track when you shake the phone (python script)

I've cleaned up the script a little :)

Re: N900 play next music track when you shake the phone (python script)

Yeah, it works. nice :)

Re: N900 play next music track when you shake the phone (python script)

thx for the nice app :D

if sum(slope)/100 > 35:
i edit the 35 to 5

and all works well XD

thx thx
