Most software development is broken into three general areas. These are the presentation, database, and business logic. Presentation logic is the software logic that is designed specifically for the screens of computer applications. This logic manages the user navigation experience with special navigation tools including buttons, scroll bars, and touch screen controls.
The presentation logic of a computer application is what makes the computer respond to commands. When a user selects a button on the computer screen he expects the application to perform a specific task. This logic enables the software a means of accepting a user’s request and converting it into computer programming logic.
Software architecture is the art of designing a complete computer application. This includes the basic screen flow and presentation logic of a computer program. Screen design is typically based on a specific hardware platform to ensure the screen fits within dimensions and characteristics of the hardware device.
Smart phones have become a popular computer device. The presentation logic of a smart phone enables a user to send emails, take photos, and manage music. This logic is responsible for coordinating the user’s interactions with the smart phone device and the software inside the phone.
The presentation layer of a computer applications works closely with business logic. The business logic is the specific process the application is expected to complete. This screen flow ensures the application smoothly interacts with the user’s commands to complete an entire process.
Human factors engineering is the scientific study of human interactions with a computer. This science focuses on developing computer applications that are more intuitive for humans. Human factors works closely with the presentation logic of a computer program because the presentation layer is the interactive portal of a computer program.
Game programming is one of the better examples of presentation logic for computer software in practice. These programs are designed to take the input from game controllers and force characters on the screen to perform tasks. The presentation layer of a game program is one of the most complicated portions of software code developed. It must seamlessly react to movement from the user with split-second response time.
Many modern computer applications can respond to human movement through special cameras and infrared devices. These game applications have created virtual environments that make users feel they are inside the actual game system. This has revolutionized the presentation logic of game programming into an interactive experience.
