Multimodal Kitchen Converter

This application is defined to aid in cooking. It makes easier using and including volumes (Pint, Quart, Tbsp, Tsp, Liter) and weights (Lbs, Oz, Kg, Gram, Mg) in cooking and baking. Whether we convert from teaspoons to tablespoons or from standard to metric this application is here to help (like in "Kitchen Unit Converter" app).
In addition to the tactile, users of this application can also speak, shake, orient and be close to the phone in order to give input commands. To give the converting value, they can write it using touch keyboard or press the down volume button and then say it if they want to avoid touching the screen. Similarly, they can touch the button “Convert” or shake the phone to get the result. Finally, to change the current activity they can touch the button (volume or weight) or orient the phone ("up" to go from Volume activity to the Weight activity and "Down" for the reverse) while being physically close to it (covering the proximity sensor). In output, the system in turn displays the conversion results.
