Experimental Design For Interactive Applications Assessment Answer

The GOMS is regarded as a human information model processor for the purpose of the human interaction observations, which highlights a user cognitive structure on four components. On this model, has been regarded as one of the few that has been known as the concept of theoretical to any of the human-computer interaction. (Nath, 2015)The idea has spawned much research to verifying and to extending the original work; it has been recently used in the real world design and situations of evaluations. On the essay, it will synthesize on previous work on GOMS to the provision of the view that is integrated on the models of GOMS and how they can be used in the design. Moreover, it will also explore how the GOMS is evaluated and how it can be used to support the development, evaluation and the various performance measurement to the mobile applications (Nath, 2015).

In the recent years, there have been concerns on whether the mobile systems should be evaluated in the field or to be more traditional in the environment of the laboratory.  Researcher on usability and the specialists has been concerned that the laboratory evaluation does not adequately simulate the context on where the mobile systems are used. The GOMS has been found to support the field tests in various ways. (Maxwell, 2012) This is so when it is combined with an additional theoretical mechanism. This primarily highlights ways to quantitatively predict both the learning and the performance of an interface design. The GOMS also serve as useful components for a qualitative description of how the users can use the computer systems in performing a given task. (Hinkelmann and Kempthorne, 2012) Besides, it is helpful to predict the performance of a task in such a way that it can be used as a substitute for many of the empirical user-testing field, which is needed to formulate a system design, which can be functional and usable. The predictive function is thus presented by GOMS model. (Maxwell, 2012) The field test strategies are mostly built around the standards. There have development and refining of the models that are introduced for the purpose of the user testing disciplines as the technology changes over time. For example, the quantitative models of GOMS have been used within the different setting at varying levels of the success. (Maxwell, 2012)  The test fields are equipped with model cognitive concepts of the users, their tasks and the design components of collaborations. This model has stood in all the test of time and has worked very well in many of the lab-based configurations more so at the within the mobile computing. Therefore, GOMS needs to be appreciated by the way they have supported the field tests.

When carrying a GOM analysis, it involves defining it and highlighting informal notations on the goals of the users, the operators, the methods and the rules of selection. Primarily most of the works involve setting the goals and the methods. (Mayilvaganan and Kalpanadevi, 2014)The hardware and the lowest level of the software of these systems usually determine the operators. The selection of the rules is subtle, and it involves multiple explicit methods for the same goals. A good design thus has a clear process if each of the methods is adopted to define the selection rules easily. Example on collection data on GOMS the analyst relies on a task which may require a judgment in regards to how the users view the responsibilities in regards to their natural goals, how the tasks are composed in the subtasks and the various functions method that are used by the users. (Mayilvaganan and Kalpanadevi, 2014) It is sometimes very possible to collect data on how the users view and decompose on the different roles, and it may be difficult at times due to the issue of the time and the cost constraint factors on the interface of the design process.

There are various theory to explain on the evaluation of the GOMS model. One of the theory is unified theory of the acceptance and use of the technology. (Jung and Jang, 2013) On this theory, it explains on how to integrate the primary competing user acceptance models. The argument is aimed at how the users intend to use the interactive system and the subsequent usage behavior. The theory combines various components on the approach, like TAM, IDT, and TPB. Nonetheless, it has multiple core determinants of the intentions and the usages. (Jung and Jang, 2013) These are performance expectancy, the social influences, and the conditions for facilitating. Moreover, it is important to look at the innovation diffusion theory of evaluation. (Bhatti, Bouch and Kuchinsky, 2000) The method tends to adopt new practices for assessment and the technologies in the society to various groups.  The theory aims at predicting how the use of GOMS has been approved at the different adopter categories of the mobile applications. Various factors may affect the rate of the adoption and evaluation these are the compatibility, complexity, observability and advantage. The GOMS model describes the procedure of the knowledge, which the user should have to operate. They are the original approach to the model based evaluation in the computer user interface. The GOMS concept is primarily based on the theory of the human problem-solving skills and the acquisition.  It entails writing a method to accomplish the task goals of interest and then it can predict the usability metric from the method of presentation. In the recent times, it is widely known that adapting established methods to the mobile environment is very challenging. (Guindon, 2013)The concerns and the various challenges that surround the empirical evaluation of the mobile systems are usually derived from the mobile and the changing dynamics of the unpredictability of the context use. The field experiments with the real users are necessary for the evaluation of the mobile interactive systems. When one is inspecting the user behavior and experience, the effects and other issues relate to the mobility and the natural use of the context (Guindon, 2013).

Conclusion

The GOMS is essentially an established for the purpose of characterizing on the user's procedure for knowledge. When the GOMS is combined with the additional theoretical aspects, it can predict the human learning and the performance of an interface design. Besides, it serves as a useful description on how the users utilize mobile applications to perform a different task. In this paper, it has explained on the concept of the GOMS providing an appreciation it brings on the support field tests. Nonetheless, it has evaluated on the use of the theories and how the data has been evaluated and analyzed.
