Keystroke Level Model Form Analyzer (KLM-FA)
Usability of interactive web forms is a critical aspect of the overall user experience. KLM Form Analyzer (KLM-FA) automatically evaluates web form filling tasks. The tool carries out Keystroke Level Model symbolic calculations of the time required to fill a specific web form in a straightforward and automatic manner. Moreover, it calculates the form completion time according to different interaction strategies or users’ characteristics. In addition, Fitts’ law is computationally realized to calculate the exact time required to move the cursor to the form’s elements. Preliminary case studies illustrated the tool capability to support both designers and evaluators in an efficient and effective manner
