Assignment Task

Assignment 2 - Report (IoT System Design)

Purpose:

This assignment aims to demonstrate your ability to design an Internet of Things (IoT) system for a sample case study focusing on user experience design. In designing the system, you need to apply the skills you have learnt in this unit to provide the best implication for the user experience design of an IoT system.

Your task in brief:

• You are required to propose and design an Internet of Things (IoT) system for a case study/area. The case study, which you design the IoT system for, is of your own choosing. The case study must be relevant to the area of IoT that you have worked on in assignment 1.
• The IoT system you propose should be of small to medium size/complexity.
• To design the proposed IoT system, you will need to thoroughly analyse the case study and its requirements.
• You should work on this assignment individually (This is NOT a group assignment).

Scenario and requirements:

Imagine that you have been employed by a company (or asked by the company you work for) to design an IoT system for a specific area. In the course of this assignment, you will prepare a design report using the provided template for the proposed system.

Your planning report must

i. use the template provided on MySCU under the assignment menu

ii. be no more than 2500 words,

iii. use a formal and academic writing style with a clear structure (Harvard),

iv. include an executive summary, introduction, body, and conclusion in your report,

v. use headings if appropriate, and

vi. address each of the following steps to complete the report:

(1) Identify the case study – Select a case study to apply your designed IoT system. The case study MUST be in the area that you have already evaluated critically in Assignment 1. Relevant application areas within IoT include, for instance, smart homes, smart cities, wearables, connected industries, IoT in agriculture (smart farming), connected healthcare, smart energy, smart learning, connected cars, smart retail, smart supply chain, and so forth.

Outline the problem description, system capabilities, and expected benefits (maximum 250 words).

(2) The connected devices (things) – Identify all applied connected devices to pair with your IoT application’s needs. For each connected device, define the following specifications (maximum 250 words):

a) Type of the connected device: specify whether it is a multipurpose computer, specialised embedded device (embedded hardware/software), connected sensor, or passively trackable object. (e.g. a light with an embedded motion detection sensor, a temperature sensor, …)

b) Specify whether it is a sensor or an actuator. Give more details.

c) Powering type of each device (e.g. battery, solar), and how the powering affects UX.

d) The accuracy level of the sensors (e.g. a temperature sensor accurate to within +/- 2 degrees)

You must identify at least four connected devices/sensors and justify them. Provide a table to list all connected devices with the details outlined above.

(3) The technology of connectivity – Define how the connected things communicate with one another and/or with different networking components. (maximum 250 words):

a) Select the connectivity type of each device/sensor (e.g. WiFi, Bluetooth, RFID,

NFC, ZigBee, …)

b) Describe whether each device is connected intermittently or always-on.

c) Describe how important latency and responsiveness are in your system. Explain how you manage expectations in designing around the limitations.

d) Provide a system architecture diagram of your IoT system (System architecture defines the path through which one device connects to another). Describe what architecture form you will implement for your IoT system (e.g. Dedicated gateway, smartphone as a gateway, direct internet connection, device-to-device connections, service-to-service connections).

e) If there is a local network involved in the system, specify the type of the network (e.g. Bluetooth, proprietary radio, ZigBee and Zwave, etc.)

f) Specify the network communication pattern of each device (push, pull, or polling), and justify your choice.

g) Specify an IoT application protocol for your system with justification (HTTP or MQTT)

h) Provide a map of the interrelationships between devices in your system from a network structure (e.g. figure 3-25 in the reference book).

(4) People and Context – Complete the following tasks (maximum 250 words):

a) Provide a list of relevant actors, stakeholders and roles.

b) Identify the needs of each actor/stakeholder of the system (Taxonomy of user needs).

c) Provide a table to represent starter questions about actors and roles (See table 5-1 of the reference book).

d) Explain different aspects of the context of interactions for each device and for the system as a whole (e.g. operational, behavioural, sociocultural etc., if relevant).

e) Provide a table to represent starter questions for each aspect of context (See table 52 of the reference book).

f) Describe if you prefer to use any technique and tactic in order to answer the questions about investigating people in context (e.g. maps, timelines, diaries etc.).

(5) Product/service definition and strategy – Complete the following tasks (maximum 250 words):

a) Describe how your system combines devices and services.

b) Provide a table to represent what devices/services are the focus of UX.

c) Explain the business model of your IoT system. Describe if your system will generate new business from new customers or generate more business from existing customers.

d) Briefly describe how you will bring your digital business model to the selected physical products in your IoT system.

(6) Interface and Interactions – Complete the following tasks (maximum 250 words):

a) For each of the connected devices, determine the interaction type (input/output). Specify the form of interaction (e.g. physical controls, visual and screen interfaces, audio and voice interfaces, gestural interaction and so on), and justify that.

b) Describe the primary means of control of the system. If there is a mobile app/software/web UI as the primary means of control, give details of the user interface. Use wireframe software to prototype everything representing various elements of the screen (pages, options, menus, buttons, input and output elements, etc.); if there is any hardware as a primary control unit of the system, elaborate on that.

c) Discuss the accessibility of the devices and the system as a whole. Provide an accessibility table with appropriate questions.

d) Discuss how you intend to make your system interactions universal.

(7) Cross-Device Interactions and Interusability – Explain how in your design, UIs work together to create a coherent understanding of the overall system and how the user may move between using different devices (maximum 250 words):

a) Provide a conceptual model of your system (including user and design model) and draw a relevant diagram(s).

b) Determine the right composition pattern for the service and provide the diagram. How has the composition pattern been selected in accordance with the UX design principles of IoT?

d) Explain the continuity of your system. Discuss whether the flow of data and interactions is in a coherent sequence across devices. How have you addressed data and content synchronisation in your system? Justify your answer with technical reasons.

Note that your system’s conceptual model and composition should be in line with your system architecture.

b) What requirements have you considered to design a usable IoT security in your system? (Limiting the damage that can be caused, keeping devices secure, making authentication easier, etc.)

c) Discuss the Information and data privacy of your system. Explain if there are any predictable privacy issues relevant to any stakeholder in your system, and how these issues are addressed.
