Activity-Centered Design: Why I like my Harmony Remote Control Computer applications that run on desktop and laptop computers have, for a long time, been designed to be driven by dragging and clicking a mouse. With the introduction of tablet personal computers, the trend has shifted toward using touch-based screens.

We now have access to touch-based TVs, touch-based monitors, touch-based laptops and touch-based tablets. Touch and multi-touch devices provide end users with the ability to interact physically with an application much more naturally. Imagine that you are the Information Technology Director of a major chain restaurant, and you have been assigned to design a menu ordering application that can run on all devices. Examine whether using a touch-screen monitor, a tablet, or using a mouse to select menu items to place an order would be most efficient. Speculate how employees would interact with these devices and the type of emotional reaction that customers and employees will experience while placing a beverage, appetizer or entrée order.

Write a four to five (4-5) page paper in which you: Differentiate between the interaction types and styles that apply to multi-touch screens and applications running on them. Determine the conceptual model that you would use when designing a product for your restaurant. Describe the key analogies and concepts these monitors expose to users, including the task-domain objects users manipulate on the screen. Determine one (1) utility / tool in an application for touch-based and mouse-drive screens that should be designed with memory retention / recall. Provide a rationale for your response.

Paper For Above instruction

The rapid evolution of user interaction paradigms has significantly impacted the design of interfaces across various devices, especially in settings such as restaurants where efficient and intuitive ordering systems are crucial. This paper explores the interaction types and styles relevant to multi-touch screens, designs a conceptual model suitable for a restaurant ordering application, examines key analogies and task-domain objects exposed by touch monitors, and identifies a utility that benefits from memory retention designed for both touch-based and mouse-driven interfaces.

Interaction Types and Styles for Multi-Touch Screens

Multi-touch screens support a range of interaction styles, primarily gesture-based interactions that distinguish them from traditional mouse-based systems. The predominant interaction style is direct manipulation, where users physically interact with displayed objects via gestures such as tapping, dragging, pinching, and multi-finger gestures, providing a sense of immediate control and feedback. These devices facilitate a natural interaction style, mimicking real-world actions, which enhances usability, especially in fast-paced environments like restaurants (Norman, 2007). The interaction style emphasizes fluidity, responsiveness, and tactile engagement, which can lead to a more immersive user experience.

Conceptual Model for Restaurant Ordering Application

The conceptual model underpinning an effective restaurant ordering system should focus on clarity, ease of navigation, and intuitiveness. A proposed model revolves around the metaphor of a digital menu, akin to a physical restaurant menu but enhanced with interactive features. Users, whether employees or customers, manipulate task-domain objects such as menu categories, specific food or beverage items, modifiers, and order summaries. This model emphasizes affordances like tappable images for items, swipe gestures to browse categories, and drag-and-drop for customizing orders, which mirror the physical task of selecting and modifying dishes. This analogy helps create a mental model that users can quickly grasp, reducing cognitive load and error rates during order placement (Norman, 2010).

Key Analogies and Task-Domain Objects

Touch monitors expose key analogies such as the "digital menu" representing physical menus, "shopping cart" for order review, and "customization" interfaces corresponding to adding or modifying items. These analogies serve to bridge user understanding by mimicking real-world objects, facilitating a seamless interaction. Task-domain objects manipulated on the screen include menu categories (entrees, appetizers), individual items, customization options (e.g., size, toppings), and order summary containers. Carefully designed analogies and object representations promote intuitive use, reduce learning curves, and support task completion efficiency (Dearden, 2008).

Utility / Tool for Memory Recall in Touch and Mouse Interfaces

A critical utility in such applications is the "Order History" feature. For both touch-based and mouse-driven interfaces, this tool should be designed with strong memory retention capabilities, allowing users to quickly access previous orders or frequently ordered items. The rationale is that customers and employees alike benefit from reduced repetitive input, faster order placement, and personalized experiences. For example, a regular customer could tap into the history to reorder favorite dishes, while employees could use it to streamline repeat orders, enhancing efficiency and satisfaction. The interface should include visual cues and persistent icons for easy recall, supported by backend data that stores past interactions securely and reliably (Norman, 2007).

Conclusion

Designing for multi-device restaurant ordering systems requires a nuanced understanding of interaction styles, conceptual models, and user mental models. Multi-touch screens facilitate direct manipulation, providing a natural and engaging experience, but demand careful conceptual alignment with user expectations through analogies and task-object representations. Moreover, integrating memory utilities like order history enhances usability, efficiency, and personalization. As technology continues to advance, embracing these design principles will be critical to creating intuitive, emotionally satisfying ordering experiences for both customers and staff.
