HUMAN COMPUTER INTERACTION AND DESIGN2
1. Introduction:
The assignment concentrates on the analysis and findings of interaction of a smart home
device that can monitor and control customer buying behavior. The proposed system is proposed
to be connected to a mobile application. The application screen will be used as the interaction
medium (Lazar, Feng and Hochheiser 2017). The interaction between user and system is one of
the most important factors in system design. The human computer interaction is a vast topic and
it can be applied to any situation where user input is required for dynamic system behavior.
The assignment includes the analysis and findings of human computer interaction of a
smart home system. This system will be developed by a super market. The purpose of the system
is to allow the customers interact with a smart IoT device which is synced with a mobile
application. The first section of the report provides background information so that every bit of
analysis done in the assignment can be understood. In the next section, the conceptual design and
various processes related to it will be discussed. Finally the actual interface or high fidelity
prototype will be developed based on the all the findings of analysis.
2. Background:
Smart can be considered as a term for referring to modern homes that have lighting,
appliances and various other electronic remotely controlled devices. A smart home allows the
user to control all these electronic devices from remote location (Dorri et al. 2017). The purpose
of the smart device is automating some of the home related works. The smart home is developed
based on a connected smart devices. In order to make the management easy, smart homes
include a small controller which can be connected to all these smart devices. The owner can
communicate with this controller using various mediums like mobile apps, voice control,

gestures and more. The connected smart devices are extremely dynamic because controller can
give command to various devices to accomplish one task (Fernandes, Jung and Prakash 2016).
Taken as an example, if owner commands the controller to switch off all the fans and lights, then
controller commands all the fans and lights separately to complete this one task.
The sync or synchronization is that many devices are connect with each other in the same
state. If controller device and mobile application is synced then both these things can have the
same data at a given point of time. It can allow the smart device to show the visual on the app
against a request submitted to controller (Quick and Choo 2018). The voice control is the input
medium. It allow the owner to control the device using voice input. Taken as an example, if TV
is connected to smart controller then by just talking to the controller, owner can watch TV.
2.1 Processes and Frameworks for Interaction Design
User Centered Design: The user centered design focuses on the user. It is a set of
processes and at the center of all the processes remains the user. In user centered design, the final
product is designed considering the requirement, feedback and objectives of the user. User
centered design is famous of improving the user experience. As the main focus remains on the
user, the proposed system’s goals, tasks and user flows are based on user requirements
(Witteman et al. 2105). If the customer experience is the primary goal of the system, then user
centered design can be the best choice. The principles of user centered design are as following.
i. Task and user requirements are clearly identified
ii. The system requirements and system design is developed based on user feedback
iii. Design processes have to follow rules of iteration
iv. Many development activities must be associated with user centered design
