Exploring user effort involved in using history tools through MHP/GOMS: results and experiences
نویسنده
چکیده
MHP/GOMS is used to examine the user effort involved in reissuing commands with and without using history tools. Compared to typing, using a history tool for command specification requires more mental effort but less physical effort. However, non-expert typists expend less overall effort using history tools. Also, based on our experiences with using MHP/GOMS to explore ‘‘what if’’ scenarios, we found some serious gaps and limitations. More research, documentation and training is required. Despite the drawbacks, MHP/GOMS is useful as a ‘‘tool for thought’’, as a ‘‘tool for explaining user behaviour’’, and as a basis for analyzing the user effort issue.

Modeling Steering Using the Queueing Network - Model Human Processor (qn-mhp)
The Queueing Network Model Human Processor (QN-MHP) is a computational architecture that combines the mathematical theories and simulation methods of queueing networks (QN) with the symbolic and procedure methods of a GOMS-style task description and the Model Human Processor (MHP). Using QN-MHP, a steering model was created to represent the concurrent perceptual, cognitive, and motor activities...

متن کاملAI Support for Building Cognitive Models
Cognitive modeling techniques provide a way of evaluating user interface designs, based on what is known about human cognitive strengths and limitations. Cognitive modelers face a tradeoff, however: more detailed models require disproportionately more time and effort to develop than coarser models. In this paper we describe a system, G2A, that automatically produces translations from abstract G...

We propose a new diagrammatic notation system for Goals, Operators, Methods, Selection rules (GOMS), called Codein, with extensions to support the evaluation of Reality Based Interaction Styles. The proposed notation gives added power to GOMS to 10 model and evaluate the task completion time of parallel actions during the performance of a task, something that was previously only possible using ...

In recent years, the development of the use of location-based tools has made it possible to produce geometric trajectories from the user's movement paths. In this way, users' goal of traveling and related activities can be considered in addition to the geometry and route shape. the user activity trajectory represents the sequence of the visited activities and its related analysis as presented i...
