GOMS-TLM model

Using the operators associated with GOMS-TLM you will write a model for taking a video using a cell phone where the user must zoom into the subject. You will start the model with the phone in a state where the camera is not activated. The camera app will also possibly be on a screen that is not the default screen. The video must be taken in a horizontal mode ( see [login to view URL] ). Use the correct operators associated with Touch Level Model (TLM). You will use the notation associated with CPM-GOMS. I highly recommend using Gogulator (available at [login to view URL] ) - it is possible to write a GOMS model using notepad - but Cogulator is a specialized GOMS editor that recognizes all the models and operators that you will use. Selection of the level of detail here is important.
