Direct Manipulation - Assignment Example This involves the continuous representation of given subjects and objects in addition to the rapid, incremental and reversible actions and their subsequent feedback. As a single characteristic, in reference to a class of various interaction styles, direct manipulation entails the direct mapping, between the semantic and syntactic level of dialogue/ interaction. The three core principles are found in direct manipulation. These include: - the end result of a systematic replacement of complex computer command-language syntax with the direct and visual manipulation of the object(s) under focus; the continuous representation of actions and objects of interest in relation to meaningful visual imagery; which is followed by the presence of rapid, reversible incremental actions, immediately visible in the objects or actions of interest. In the context of video game application, the first indicated principle is achieved through physical actions (button presses), rather than the use of typed commands (Shneiderman & Plaisant, 2010). Through varying gaming pads, the other two principles are achieved best in a 3D dimension, where the objects and actions fit into role-playing games. Users are able to control virtual avatars, with the keypad buttons enabling the change of movement, scenery, actions and interactions in the virtual worlds present. Video gaming interfaces are unique in nature, with the aspect of 3D enabling greater contrast, between the virtual and real (physical) worlds. The user, interacting with the present operating system (hardware and software), is able to manipulate directly, existing objects to perform specific actions. Such systems enable the reversal of such actions, in addition to the creation of virtual reality unimaginable in the existing physical world. This entails the direct interaction between the user, and the objects/ actions, thereby enhancing
