The multi-touch screen technology is a significant research field in the Human Computer Interaction which is acquiring momentum with the introduction of business products including Diamond Touch and Microsoft's Surface (Renzi & Freitas, 2014). Modern companies are utilizing multi-touch screen applications in relation to the mouse-driven screen to run various business applications. This advancement is gradually replacing the traditional input devices including keyboard, sensor mouse, and even the stylus with an LCD surface technology which provides up-to-date approaches of interacting with information. At the same time, the multi-touch screen technology supplies the end users with the digital tools involving processing of a large amount of text and information (Renzi & Freitas, 2014).
Differentiation between the Interaction Types and Styles
Multi-point interaction and resistive touch style give a user the opportunity of touching various control points within a particular compound task (Saffer, 2008). This interaction allows the end user to modify the properties of the items with an immediate touch. Moreover, the resistive touch is apportioned by a narrow gap that lets the consumer slide through the screen with one's fingertip. Most predominantly, when the buyer touches the display, the pair of metallic layers interact, therefore, generating an electrical flow. The resistive touch can be triggered with virtually any object such as a stylus, a finger, a pen, a hand, etc.
Multi-user interaction and Side-Sight style are applied to infrared multi-touch screens and applications. The infrared (IR) multi-touch displays utilize infrared transmitters and receivers to generate an invisible network of light beams across the display (Renzi & Freitas, 2014). This approach guarantees the ideal image quality. However, when an object hinders the transmission of invisible infrared light beams, the IR sensors determine the location of the touch point. The IR touch screens are resistant to surface scratches and provide the best image clarity and light emission to all multi-touch display technologies.
Furthermore, surface capacitive touch is another interaction type and style of a multi-touch screen. It has a transparent electrode coat installed on the surface of a glass panel. A protective layer encloses this glass to prevent it from unfavorable contacts such as water. Notably, when an exposed finger contacts the screen, it responds to the static electrical discharge of the human hand (Saffer, 2008). Moreover, the monitor sensors detect the reduction in capacitance allowing the controller to find the touch point with the hand. A stylus that has an electric charge can also activate these multi-touch screens.
The Surface Acoustic Wave (SAW) interaction relies on ultrasonic waves for detection. The SAW multi-touch screen encompasses one glass sheet with conducting transducers, receiving transductors, and reflectors (Saffer, 2008). These transducers produce ultrasonic waves which travel over the surface of the glass panel. The display reflectors, then, emit the waves and the sensors receive them. Hence, this significant action allows the transducers to identify the touch point and transmit this data to the computer. Notably, the SAW touch screens can be triggered by a finger, hand, and dedicated stylus. They are ideal when transmitted in the light presence since it involves a single glass layer. Besides, it has a good visibility and the image clarity.
In addition, projected capacitive touch offers capacitance between the object and the electrode located in the sensor grid (Saffer, 2008). When an object such as a finger comes in contact with the screen, the divergence of the electrodes changes and the device is able to notice the touch points. Finally, the screen produces an image of a good quality and is invulnerable to the surface scratches.
My Conceptual Model for Designing a Product for the Restaurant
A conceptual model displays how the graphical user interface for an application will look like (Renzi & Freitas, 2014). The application will utilize a touch screen monitor as it provides efficiency and guarantees new approaches of interacting and collaborating with information. I anticipated that after the user's logging in the system, all the views for the menu ordering application will involve a static navigation bar appearing on top of the window. In addition, it will also have a static bar on the bottom of the window. The navigation bar at the top shall include an icon that allows users to view products presently in the cart, whereas the bottom navigation tab will hold significant menu items such as settings, listed payment methods, etc. Therefore, the employees will interact with the menu items and select suitable food. Furthermore, the customers will view the images of the products via navigating the menu using touch screen monitor, which will create both emotional and utility experience with the viewed products. Consequently, the customers will place various orders such as appetizers, beverages, salads, chicken, rice and other relevant dishes.
Key Analogies and Concepts the Monitors Expose to Users
The multi-touch monitors present constant intuitiveness to the end users. The tasks performed to navigate through the menu ordering application of a chain restaurant are more adaptive. Thus, they become naturally and intuitively understood and envisioned by the end users. Intuitiveness happens with the utilization of the touch screen because of introducing the familiar application to the customer (Dearden, 2008). Hence, the consumers know how the application will behave before interacting. Additionally, the users become more efficient as touch monitors consume less time than a traditional keyboard or a mouse.
The touch screen offers user-friendliness when the customer interacts with it (Renzi & Freitas, 2014). In fact, a minimum technical knowledge is required to run the multi-touch screens. As a result, it makes the process of engaging with these monitors user-friendly. Moreover, this approach assists the IT directors in establishing the terminals within the business stores in the effect that customers have positive experiences while using these touch screen monitors.
In addition, the multi-touch screens offer the best approach for user cooperation. They provide interactive experiences especially when the department engages clients and collaborates on the tasks. Rather than relying on the mouse for control, the power of control will be on everyone's palms. Moreover, the multi-touch screens provide productivity, which guarantees a quick completion of the projects and a workplace collaboration (Renzi & Freitas, 2014).
The multi-touch screen exposes clarity and conciseness to the end-users. The screens generate images of sound quality, for instance, infrared monitors. Besides, information presented on these screens is concise with few details to enhance the user comprehension and interactivity (Dearden, 2008). Additionally, the task domain objects such as menus, links, and navigation bars are clear and easy to use. This conceptual method of the touch monitors increases the greater accessibility to the applications.
The multi-touch display presents interface metaphor or analogies that allow the users to apply them as abstractions, which could simulate the real world. These monitors permit the end-users to utilize their knowledge about the known fiction and scenarios to provide the structures to less comprehensible concepts. For example, a user can drag the objects such as menu items from one private touch screen to another public touch monitors (Dearden, 2008).

The Tool Designed With Memory Retention
The interactive utility is a critical tool in the application that should be developed with memory retention. The applications for both touch screens and mouse driven monitors should adopt the interactive tool. For instance, the utilization of interactive images in the application for both touch monitors and mouse driven screens is more likely to be recalled if the pictures are moving dynamically rather than being static. Importantly, when objects are associated, for example, moving images or slides, they attain interaction (Renzi & Freitas, 2014). This strategic technique improves the memory of the user since one tends to remember interacting pictures or the text in an application for either touch screen or mouse-driven screens.
In conclusion, the multi-touch monitors are imperative to the modern business industry as they enhance interaction with the end users. They also provide the end customers with the great performance of digital utilities. Therefore, the management should determine the ideal type of the multi-touch screen for running the business applications. Evidently, these screens will ensure information intuitiveness, user friendliness, data clarity, user collaboration, and interface metaphors. Consequently, the management will easily communicate with the clients in a more meaningful way.
