Devices are designed in a manner that allows the user to input commands and receive outputs through display tools. The user interface allows the communication between the user and the system. This paper discusses the concept of interactive framework and assesses of the functionality of a cell phone
Part 1: The Concept of Interaction Framework
The concept of interaction framework focuses on the way a system user interacts with the system on the interface. It is also the way a system communicates with the user through the user interface. The interaction framework of a system consists of four elements of the system. This entails the core language, the user consisting of the task language, the input comprising of the input language, and the output consisting of the output language. The interaction cycles occur in phases of execution and evaluation (Milkner, Buhler & Dybkjaer, 2005). Moreover, execution is perceived as the articulation of the goals through the input language, performance through core language and denotes the operations that the system will carry out, and finally, the presentation through output language and manifests the operations carried out by the system. In the evaluation phase, the user has the task of interpreting the results that are displayed on the screen and compares them with the initial goals of the input task. The main importance of interaction framework as a concept is to allow the user to contextualize the task in a global view (Jones & Marsden, 2006).
Part 2: Device Assessment
The device selected is a simple cell phone that has common functions such as making calls, saving contacts, logs register, internet applications, files, calendar, messages settings, and clock among other features. The device interface is explicit of the functions that can be performed by a cell phone. On the standby mode, there is a menu button that directs the user to the features. The icons are such that they can reveal to the user what function to perform. The primary function of a cell phone is to make calls and this function can be accessed on the standby mode without having much input from the part of the user. The cell phone can perform other functions such as accessing the internet through the Web application icon, storing of files in folders, and storage of music both audio and visual in a music folder. The device also has a memory card that allows the storage of large music files. The cell phone can perform symbol mathematical calculations using a calculator, has a convertor, games, edit images, dictionary among other functions. All these functions are accessible via the menu button. The icons are in such a manner as to denote their functions.
With several functions that the cell phone can perform, the user forms a mental intention of what she or he wants to perform using the cell phone. For instance, in accessing the internet application, the user knows that there is an internet application on the menu and thus accesses it through the physical pressing of the menu button that opens up to a number of features. The user then scrolls down to the internet features and opens it through user input. The system understands the command from the user and promptly performs the function that the user has requested, after which results are displayed in a manner that the user can understand.
The desired action is performed through menu button. The button is accessed through the physical buttons on the interface. Some cell phones have touch screens that allow the user to perform an action by the finger, but these are technologically advanced cell phones. The performance of a desired action starts with the user setting a goal of an action that needs to be performed. The mental perception of the procedures and the available features also help the user to have a physical interaction with the cell phone through the user interface on the standby screen.
The system on the cell phone is set to respond to the requests that are entered by the user. For example, the user has the ability to modify the default settings on the cell phone, such as the font type, screen color, icons, or the general functionality of the cell phone via the factory settings. The changed mode is applied to all other features in the system such that the user is not required to change the feature every time he or she wants to access it. For instance, a change in the color of the screen will be applied to all other features in the system and become the default settings of the system. This prompts a gulf in the performance of the system during the evaluation and execution phases.
Part 3: Evaluation of Selected Style
The selected interaction style is suitable for the functionality of a simple cell phone that is used by many users who do not have technical knowledge about operation of the cell phone. The style allows the user to access most of the features on the device through a single button menu and this likely simplifies the need to have difficult tasks performed by the user. Furthermore, the device has directories and guidelines through drop down features that gives explanations to each and every function that can be performed on the device. The physical features allow the user to input the characters in the language that best suits them. Similarly, the output is displayed on the screen in a language that is understandable by the user. In essence, the core language of the cell phone can be customized to suit the input language and output language so that the user gets exactly the results, which are requested. The style also allows the user to have an interactive user interface between the user’s goals and intentions and the capacity of the cell phone system to interpret the input and process the output (Milkner, Buhler & Dybkjaer, 2005).
