- 1. MMIS 680 Human Computer Interaction Answer: Introduction Human computer interaction or HCI is found to be an interdisciplinary study field emphasising on computer technology design and specifically, the interaction between computers and humans. HCI is found to serve as beneficial for any business entities that are found to be highly reliant upon computers and technology for executing its operations. Thus, from the next adjoining section, differentiation between interaction styles and types that incorporate multi-touch screens will be underlined. Additionally, conceptual models for designing products for restaurants, key analogies, and utility tools will also be highlighted in the following section briefly. Interaction Types And Styles With the growing dependency on computers along with electronic devices, users are found to be looking for the most appropriate and suitable technologies that enable them to interact with availed technologies easily. It is identified that Capacitive is considered as one of the most commonly identifiable types of touch screen technology that support multi- touch screens. Capacitive touch screens are found to utilise capacitance to identify specific touch commands. There are different types of capacitive touch screen such as mutual, self, and projected that are found to support multi-touch screen operations. On the other hand, SAW (Surface Acoustic Wave) touch screen technology is also found to support multi touch screens and they operate through emitting sound waves and ultrasonic waves over the surface of the respective display interface. In contrast, it is identified that previously, resistive touch screen technology failed to support multi touch screens (Lee et al. 2018). However, presently, Resistive touch screen technologies support multi-touch operations. This technology is found to work on the multi touch screen by emphasising on pressure for detecting specific touch commands. Each of these interaction types and styles are found to operate and work based on the requirement and utility of the multi touch screen user preferences. In most of the cases, it is identified that capacitive technology is being utilised for multi-touch screens to run on applications such as smart and mobile devices respectively (Seol et al. 2019).
- 2. Conceptual Model While designing products for restaurants, it would be required to analyse the demands and expectations of the potential customers before introducing new products. As mentioned by Aikhuele and Turan (2018), with the emergence of technology, consumers are found to prefer to utilise user-friendly and technology-based platforms to purchase or order their required items from their preferred brands. Thus, in order to design products for restaurants, the following conceptual models in relation to HCI devices could be considered. User Centred Design User-centred design (UCD) is considered as the iterative design approach where designers are found to be emphasised upon users along with their needs throughout the design process (Xu, 2019). On the other hand, consideration of this model approach could serve as beneficial for obtaining clear vision and goals of the proposed projects in accordance to which proactive steps could be undertaken. Activity Centred Design Activity Centred Design (ACD) is considered as the design model that mainly emphasises upon how a specific system needs to be produced and desired outcome as activity result. This considers the border system behind a unit user. ACD model can be considered as the extension of HCI in relation to the interaction design (Bachmann et al. 2018). Comparing both the model concept, it can be mentioned that consideration of ACD model would be beneficial to design products for restaurants as designers that follow this model emphasises on research-based activities to collect user’s perspective and their needs in accordance to which user-friendly design is being developed. Key Analogies And Concepts In the context of an identified model for developing new products for restaurants, object or action analysis plays a significant role that provides a brief overview about the efficiency of the model used during the design phase of the products. As computer-based systems offer new capabilities, concepts cannot be identified in the task domain. For example, while utilising the conceptual model for designing a product, physician documents can only be organised in specific ways (Jaakkola, 2020). On the other hand, in touch screen-based platforms, documents could be categorised in multiple ways. In this regard, it can be mentioned that enumeration of the actions and objects of task-domain enable designers to identify actions that are being shared among the objects. Designers thus can utilise the same User Interference or UI for specific actions across different objects. Consideration of these aspects serve as beneficial for the designers to introduce more coherent and simpler product design.
- 3. One Utility Or Tool In relation to designing products for specific restaurants, the order system will require the potentiality to recall and retain the respective order from the particular time customer placed to the order preparation, through delivery. One tool or utility for an application in mouse-driven and touch-based screens that could be designed with the application of memory recalls or retain is “JAVA Application”. When Java Virtual Machine is being allocated to only a specific memory amount, the memory space could be increased. The touch screen “menu ordering application” will utilise JAVA to become HCI device with the customers and thus, it can be considered as one of the primary and important utility for the up gradation of the system (Gobena, 2019). Employees within the restaurants will assist their potential customers with problems, questions, and concerns while placing orders through any order platforms in touch screen. Utilisation of the mentioned utility will serve as beneficial for the restaurant as they will be able to provide a convenient and easy ordering system (Vuletic et al. 2019). This will help to generate customer satisfaction level along with speed up the overall customer service operations. Conclusion In relation to the overall discussion, it can be mentioned that HCI allows companies to obtain benefits of emerging infrastructure demands for the data-centric workloads without requiring to place resources in the public clouds. The discussion has identified that capacitive types are found to be widely utilised for multi-touch screens that run on applications such as different smart and mobile devices. On the other hand, it has been identified that the Activity Centred Design model could be utilised while developing products for restaurants. Along with this, it has been identified that JAVA Application will be the utility in application of mouse-driven and touch-based screens. References Aikhuele, D. and Turan, F., 2018.
