HUMAN FACTORS IN SYSTEMS DESIGNBy(Name) (Course)(Professor’s Name)(Institution)(State) (Date)
USABILITY EVALUATION OF AN INTERACTIVE SYSTEMPART ONE: THE INTERACTIVE SYSTEM AND ITS USERSMedical Examination Direct Iconic and Graphic Augmented Text Entry (MEDIGATE) SystemAn interactive system is associated with the modern systems that are friendly to their users because of incorporation of human factors into their designing processes. For instance, operating and understanding how these systems functions requires less human skills and knowledge. This system is a very important tool that is used by health care professionals. It was developed toenhance the relationship between patients and the physicians. In addition, it is used by physiciansto keep track of the patient’s information. Previously, it was difficult for the physicians to gather and keep the information of their patients after examining their conditions. Besides, this system is used to analyze another methods or systems that are used by physicians whether they are effective or not. For instance, these systems are used to explain in detail the inability of other interfaces to achieve their purpose of keeping the information of their patients. (Stanton et al 2017).Description of user populations Physicians are the main users of MEDIGATE system. The chief aim of physicians is to collect the information concerning the conditions of the patients. Also, physicians are also supposed to gather the information about the history of their patients. Some information that theyare concerned with includes the year or the time in which the problem was developed by the patient ranging from its initial stage to its current stage. The forms in which a condition has changed over time is also described by the physicians. In addition, physicians are supposed to describe the appropriate treatment that should be given to the patient. For instance, the medicine that the patient should use are also prescribed in advance by physicians (Baek et al 2011). The medical professionals that use MEDIGATE system include medical officers, consultant specialists and health care professionals such as the pathologists. Ancillary medical specialists are not directly involved in day to day patient management but are required to take clinical
history and physical examination to aid in diagnosis and direct the management of patients by the general physician.Assumption of user capabilitiesThe physician should have a background medical knowledge on medical disciplines such as Anatomy, Physiology, Biochemistry, Pathology, Microbiology and Pharmacology in order to seek support from MEDIGATE system. The physician should be competent enough in acquisition of physical findings, coexisting problems, that may be significant to the original diagnosis and may alter the plan of management. The physician should be able to confirm some elements of the clinical history during physical examination, such as inability to use a certain part of the body. However, it is assumed that physicians can gather information that is susceptible to misinterpretation by other medical specialists such as the surgeons; hence the development of MEDIGATE system, (Deterding et al 2011).PART TWO: THE USE CASESThe focus of MEDIGATE system is recording of physical examination findings. It was developed basing on the idea that the use of icons to represent different objects in the of medicine can assist the physicians to modify and record patient’s information with a lot of ease. MEDIGATE is designed to provide positive reinforcement and on-line training and to aid the health care professional in obtaining immediate feedback following data input by eliminating thedata entry clerk. Furthermore, this system ensures that the information collected is secured from attacks.The core function of MEDIGATE system is to enhance the process of examining patient’s problems and conditions with a lot of comfort and ease. Also, the system provides the physicianswith a better platform of analyzing the parts of the human body, therefore, making it easy for them to describe an appropriate treatment to the patients. This system is capable of satisfying the needs of the physicians as described by the following attributes: 1) using of an icon to represent different object, 2) interfaces that enables the physicians to develop different instances of the same command, 3) physician can enter some commands to this system anytime when the need arises, 4) the use of multithreading enabling the
users to carry out more than one task at the same time, and 5) this system can be adopted with a lot of ease.Description of the use cases The primary patient medical record is subdivided into three distinctive categories which are;1) the information regarding the history of the patient that is made up of the following; the core problem that need to be examined, the time when the problem started or developed, the previous treatments to the patient including the operations that have been carried out if any and the background of the family that the patient is coming from, 2) the results of the examination bythe physician, and 3) the record of laboratory result and the medical imaging findings. These medical records that are collected forms the baseline of prescribing the appropriate treatment thatshould be given to the specified patient by the physicians. (Proctor and Zandt 2018). PART THREE: THE EVALUATION METHODOLOGYEvaluation is the process of appraising the usability and acceptability of a product, looking at its adaptability to the user’s needs and problems encountered by the user during use in an attempt toinitiate the process of making relevant modifications that are tailored towards improving the user’s experience.The questions below are to be considered in the evaluation of MEDIGATE system physical examination interface:• Can the physical examination findings be enumerated?• What are the characteristics that can be used assess the quality of the collected information?• What are the different ways that are used by the physician to collect information?• What are the guidelines that are followed by physicians when collecting data?• What are some of the types of data that are very essential to the physician?• How can a patient determine the prerequisites of the physician when examining their conditions?• What are the challenges that are encountered when studying how the MEDIGATE system operates?
