Eye Tracking to Evaluate the Usability of User Interfaces

User Interface is that part of the equipment with which the user communicates with the product. These user interfaces are the buttons, touchscreen, knobs etc. These should be designed in a manner that every user can use it efficiently. But in reality, the users are having a fear to use it. In the present study it was found that among all the equipment’s respondents were having a fear to use the microwave oven because of it complicated user interfaces. While using the microwave oven the users are facing lot of problems which are related to buttons, knobs, switches, touch screen, etc. of user interface. 90% of the respondents stated that there are too many buttons in the interface and 100% reported that the buttons are a waste of space. 45% of the respondents reported that there is a bad contrast between the keys and the equipment same percent stated that the font size is not legible and 90% reported that the distance between the keys are not sufficient to operate it smoothly. Thus, the usability is dependent on text style, location, size, colour and visual information of the components in the user interface. When these attributes are used effectively users use the product without any problem. The need of the hour is to study the usability problems while using the products. In usability evaluation, today eye tracking methodology is mostly used which can be a guide to improvement in design of user interface.
