Press and hold the screen and your mic will be muted, when you let up it will unmute. 15 | 16 | [2]: http://eightmedia.github.com/hammer.js/ 17 | 18 | ## Installation 19 | 20 | You need a local web server running PHP and a way to load it on your iPhone. This can be done by turning on the apache web server with PHP enabled and setting up a virtual host. If you don't know how to do that, I recommend using [MAMP][3]. 21 | 22 | [3]: http://www.mamp.info/en/index.html 23 | 24 | Unzip the download into a folder in "Sites" in your home directory. Point your virtual host to it and you're ready to go. 25 | 26 | Open your virtual host address/port in Mobile Safari on your iPhone. Use the send button at the bottom of the mobile Safari window to "Add to Homescreen." Leave Safari and launch the new icon it creates. 27 | 28 | ## Usage 29 | 30 | Skype can only mute the mic while a call is active. Once you have a call started, tap and hold your iPhone screen and you should see the Skype notification that the mic is muted, unmuting when you release. 31 | 32 | To toggle, just tap lightly once. This will hard switch between muted and unmuted. 33 | 34 | If you're barefoot and don't mind touching your iPhone with your feet, it makes a decent foot pedal, too. 35 | -------------------------------------------------------------------------------- /index.php: -------------------------------------------------------------------------------- 1 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | CoughButton 30 | 31 | 32 | 33 | 34 | 35 | 36 | COUGH! 37 | 38 | 39 | 40 | 41 | 42 | 78 | 79 | 80 | -------------------------------------------------------------------------------- /scripts/hammer.js: -------------------------------------------------------------------------------- 1 | /* 2 | * Hammer.JS 3 | * version 0.6.1 4 | * author: Eight Media 5 | * https://github.com/EightMedia/hammer.js 6 | * Licensed under the MIT license. 7 | */ 8 | function Hammer(element, options, undefined) 9 | { 10 | var self = this;
