It does this by using operators that represent  keystrokes, mouse movement and presses, the movement of hand  between the two, and the the time spent mentally preparing for an  operator. While these operators are clearly linked to the desktop,  these operators can work on mobile phones as well. We present an  open source tool, KLM-Qt, that can examine events that are  delivered to an application and convert them into Keystroke-Level  Model operators. This has the advantage that all that needs to be  done is demonstrate the application to get a model, resulting in a  savings of time. We include how the tool works along with the  details of its implementation. To test the tool, we run it along with  other desktop evaluation methods for a couple of mobile phones:  the Trolltech Greenphone, the FTC Neo1973, and the Apple iPhone.  We find that these evaluation methods show promise for mobile  devices and should be pursued further when doing evaluations of  applications on mobile phones.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838355566\"\u003e\u003ch3\u003eEvaluating Mobile Phones with the Keystroke-Level Model and Other Desktop Methods\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838355566","offer_id":39469173997661,"sku":"9783838355566","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5ca7220b-fa64-44e3-9ddb-ba6e32480d2a.jpg?v=1758877716","url":"https:\/\/shop.autorenwelt.de\/products\/mobile-phones-and-the-keystroke-level-model-von-trenton-schulz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
