1. Introduction
A smart home hub which is one of the IoT devices, is to connect the smart home devices like
smart bulb, CCTV camera, door and thermostats. The smart hub connect the other devices through
bluetooth and the users can commend the smart hub with voice commend. However, the users cannot
fully manage with just voice commend of the smart hub. To manage the connected devices fully, it need
to have an application on phone, table or smart watch. (Rouse, 2018)
1.1 Background
In 2010, the company called “Nest” firstly picture the idea of smart hub. In 2012, the first smart
home hub called SmartThings, has been launched and in 2014, the system was bought by Samsung. Now
most of the company had been launched many smart hub. The most famous smart hubs in 2020 are
Amazon Echo Plus, Google Home Hub (Google Nest Hub) and Samsung SmartThings Hub. (Starr, 2020)
Apple also release the smart hub called Apple TV.
According to statistic, In 2017, only 4% of worldwide people lived in smart home rather than
traditional home, whereas in 2020, the number is up to 9.3%. This rate show The age of the people living
in smart home are mostly 25-34 years old. Thus the target users for this coursework will partially be
chosen according to that numbers. (Smart Home - worldwide | Statista Market Forecast, 2020) (See more
about the detail number of smart home users by age in Appendix A)
1.2 Classifying the Target Users
In this coursework, the design of the smart hub will be targeted to three target users. The primary
target users are the people who have been 18 to 24 years old, with having some technology knowledge
and fluent in English.
The secondary targeted users are the people who have been 25 to 34 years old, with having little
technology knowledge and fluent in English.
The third targeted users are the people who have been 35 to 44 yers old, with little technology
knowledge and doesn’t good at English.
Before drawing the design for these three target users, the design framework to be used for this
coursework will be set.

2. Frameworks
There are a lot of design frameworks to be chosen before drawing a prototype. However, in this
coursework only three frameworks will be studied and then one of them will be chosen to draw the
design.
2.1 Framework Studies
1. User Center Design
User-center design (UCD) is an iterative design process where designers draw the design with the
ideas and the needs of the users throughout the process. There are four stages in this design process;
Understand context of use, specify user requirements, Design solutions and finally Evaluation against
requirements. (What is User Centred Design?, 2020)
There are also many techniques to involve the users in this process. These are background
Interviews and questionnaires, walkthroughs, role playing and simulations and usability testing. (Abras,
Maloney-Krichmar and Preece, 2014)
2. Goal Directed Design
Goal Directed Design (GDD) is the design process which mainly put the users at the centre of the
process and make a huge attention to the needs and goals of the users. Then change these goals into tasks
and actives which will finally make the good usable design.
In GDD design process can be describes as the six steps process. These are Research, Modelling,
Requirements definition, Framework definition, Design and Development. (Amann, 2009)
3. Activity Centred Design
Activity Centred Design (ACD) is little differed from User Centred Design and Goal Directed
Design. Instead of focusing on uses needs and goals, ACD is mainly focuses on activities performed by
users. In activities, there are included about tasks and the tasks again included actions. (Saffer, 2010)
Unlike other two, ACD there is just a model. Thus it has not process like the above two, but the
designers observe the behaviours of the users using this eight actives nodes; motivation, outcome, object,
subject, community, division of labor, rules and rituals and tools and artefact. (Activity Centred Design,
2018)

2.2 Framework Used
After studying the three design framework, one of them will be chosen for this coursework. All of
these frameworks have their own meaning and process/ nodes. However, to develop this coursework Goal
Directed Design (GDD) will be the best option.
The Reason of chosen GDD is because it is mainly focus on the users’ needs and goals while
UCD is only focus on the needs and ideas of the users. ACD on the other head, does not have a specific
process, and have to observe the behaviours of the users with its defined actives nodes. Thus ACD design
will be strongly depended on the observing users’ behaviours. In GDD, the involvement of the users is
moderate and it has specific and clarify process, so not only its framework is not fully depend on the
observing users’ but also the design using this framework will fulfil the goals of the users.
As mention above, in GDD there are six design process, however, only four of them will be used
for this coursework.
1. Research - where research about the similar system and make the Questionnaires to know about the
users’ requirements
2. Requirement Definition - where define the requirements for this coursework to design
3. Framework Definition - where the initial/ low fidelity design will be drawn
4. Design - where high fidelity design will be drawn with evaluations at the end of the coursework
FIGURE OF GDD SIX STEPS (AMANN, 2009)

3. Research and Requirement Definition
There are Three main section in this Research and Requirement Definition. Analysing of Similar
System, Users Requirements Research and Requirement Definition. There are two parts to analyse the
similar system; Functional requirements analysis and non-functional requirements analysis. The detail
about the similar system analysis will discuss in the next section.
3.1 Similar System Analysis (Research)
As mention in above, this course will have four step to design this smart hub application. In this
first step, Research, there will be analysed about the similar system. In real world, there have been a lot of
smart hub devices and softwares; Among them, two of these softwares will be analysed for this
coursework; Apple Home (by Apple Company), SmartThings (by Samsung Company). In the following
there will be analysed the overall concept these two softwares.
FIGURE OF APPLE HOME KIT (LEFT) AND SAMSUNG SMARTTHINGS (RIGHT)

3.1.1 Functional Requirements
After using and analysing these two applications, three main functions included all of these
softwares. These function are as follow -
Connect Function - All of these software have the same connect function. As soon as the application is
opened they need to register the account and have to connect the other smart devices like smart bulb,
CCTV camera, door and thermostats.
Control Function - After connected the devices, these can be controlled by the software like on/ off
function, volume up/ volume down, adjust the condition and so on. There are two want to control from
these software, one is to control by touching the screen and the other is controlled by voice commend.
Real Time Function - This function is a little similar like the control function, however, this function can
see real time. Like looking the front door through CCTV camera and so on.

3.1.2 Non-functional Requirements
There will be two main sections in this non-functional requirements analyses; Cognitive
Psychology and Design Principles Used.
Section 1 : Cognitive Psychology
In cognitive psychology, there are two general modes called experimental and reflective
cognition. The first one is the state of mind that people act, react and perceive to things effortlessly and
effectively. The later one is another state of mind that people think, compare and decisions making. There
are six kinds of process to describe the cognitive psychology. These are -
1. attention
2. perception and recognition
3. memory
4. learning
5. reading, speaking, and listening
6. problem solving, planning, reasoning, decision making
However, in this coursework, only three of these processes will be adopted to analyse the similar
products.
1. Perception
Perception means how users can get information by looking at the system. In this case, the button
and symbol from Apple Home Kit is more clear than SmartThings. In SmartThings the color of the home
background is light and the words and button chosen are white, thus personally the colour chosen from
Samsung is a little confuse than Home Kit.
FIGURE OF PERCEPTION OF TWO APPLICATIONS

2. Attention
Attention is the process of getting more concentration to specific thing while other informations
are showing at the same time. In this case, both two softwares get attention of their own purpose in the
home page. In home page both of them intend the users to connect other smart devices and the connect
button of them is get attention to the users.
FIGURE OF GETTING ATTENTION TO THEIRS MAIN FUNCTION
3. Memory or Recognisable
Memory or Recognisable means the design can be memorised easily, which does not have to be
recalled what the do and how to continue. In this analysis, bot of these two design are memorisable and
clean. Thus there is no confused button, words and symbol are used to confuse recognisable.
FIGURE OF HOW EASILY RECOGNISED THE DESIGNS ARE

Section 2 : Design Principles Used
In this section, Nelson heuristic design principles will be used to analysed the similar design.
(Nielsen, 1994). In Nelson’s principles, there are totally ten principles, however, in this coursework, only
five of them will be used to analysed the similar system. After analysing the mistaken made by these
similar application, the upcoming design form this coursework will avoid them as much as possible.
#1: Visibility of system status
Analysis whether the status of both application is visible and the users have been informed clearly. In
SmartThing, because of the light wallpaper and the white text colour, the status of the system is difficult
to see for the users. The detail about the visibility of system status will be shown in the figure below.
FIGURE OF ANALYSING THE VISIBLE THE STATUS

#3: User control and freedom
User control and freedom means users have no risk to click button and if something is wrong, “emergency
exit” is visible enough for the users to use. Or the users can undo or redo the process from back to front
and vice visa. In SmartThing, the hamburger icon is more clear and give the users’ freedom to go
anywhere of the application whereas Home kit “HOME icon” is small and difficult to see. The detail
about the user control and freedom will be shown in the figure below.
FIGURE OF ANALYSING USER CONTROL AND FREEDOM
#4: Consistency and standards
Consistency and standards means users do not have to face with different words, actions or situation from
the application. In both Samsung and Apple have a little different words, however, in Apple is a personal
case. But for Samsung, a lot of similar users can get confused. The detail about the consisted and
standards will be shown in the figure below.
FIGURE OF ANALYSING CONSISTENCY AND STANDARDS

#6: Recognition rather than recall
A Recognition design means users can use the design that users does not have to recall the design while
using. In SmartThings, the design have to recall to connect the smart devices, because of the two area and
bad colour chosen. Whereas in Apple Home the home button is small and less visible, thus it also have to
recall when to go the main page of the application. The detail about the recall design mistakes will be
shown in the figure below.
FIGURE OF ANALYSING RECALL DESIGN MISTAKES
#8: Aesthetic and minimalist design
Aesthetic and minimalist design means, there should not be duplicate features or button in design.
Moreover, there should not be unnecessary informations which can lead misunderstanding for users. The
detail about the recall design mistakes will be shown in the figure below.
FIGURE OF ANALYSING RECALL DESIGN MISTAKES

3.2 Users Requirements Research
Questionnaires method will be used to make this users requirements research. In this research
Twelve people have been participated and this research has been taken by “Google Form”. However,
only eleven people have been answered.
There are three sections included in this questionnaires. The first one is personal information, the
second is about the smart hub and the last about application interface design. The detail about the
questions will be shown in Appendix B.
After researching about the users requirements, the following facts will be applied for this
upcoming design. The rest answers from the questionnaires will be shown in Appendix C.
Fact 1 : Background Colour and Text Colour
FIGURE OF BACKGROUND COLOUR AND TEXT COLOUR CHOSEN
From the research about 54.5% of the people love back background colour and white text colour,
thus the design colour chosen will be drawn according to that. However, 36.4% of the people like
background colour white and text colour black thus this colour will also be added as optional in design.

Fact 2 : Popular Font Design
FIGURE OF CHOSEN FONT DESIGN
Arial is the best choice from research thus, it will be set as the primary font design, while Time
New Roman Font design will be used as the secondary font design for this coursework prototype.

Fact 3 : Popular Button Design
FIGURE OF CHOSEN BUTTON DESIGN
Most of the people choose Button Design 2 and 3, thus these two designs will be chosen as
Primary and secondary designs. (See more about Button Design in Question Figures | Appendix B)
Fact 4 : Popular Icon Design
FIGURE OF CHOSEN ICON DESIGN
The icon design 3 will be used as the primary icon design in this coursework design and the icon
design 1 will be used as the secondary icon design. (See more about Icon Design in Question Figures |
Appendix B)

Fact 5 : Chosen Devices
FIGURE OF CHOSEN DEVICES
From the end result of the questionnaires, this prototype design will be drawn for two devices;
Phone as the primary devices and the Watch as the secondary devices.

3.3 Requirement Definition
According to research of users requirements, the participants want to get the for smartphone and
smart watch. In this coursework the prototype will be drawn for apple devices as the personal preference.
In this section, there will be defined about the iOS Design Guidelines and Watch OS Design Guidelines to
be applied for design.
3.3.1 iOS Design Guidelines
There are iOS six design guidelines to be followed. However, as this is an educational
coursework, there will be mainly three guidelines will be followed and the detail will be shown in the
table below. (Themes - iOS - Human Interface Guidelines - Apple Developer, 2020)
Number Description In detail
Guideline ONE: Consistency Consistency design means using general icons,
terminology, design elements and typography which
users will easily understand and easy to use. Thus this
coursework design will only used general icons, design
elements and typography which users have been used to.
Guideline TWO: Feedback Feedback are used to know what users are doing and
what users did. To show the feedback, the designs are
typically shown by animation, sound and vibration. In
this coursework, to get user acknowledge the feedback
will mainly be shown by animations.
Guideline THREE: User Control Users Control means in case if uses make the dangerous
decision like delete the connected devices, they have
been asked for double check whether it is a wrong
decision or mistakenly touch. In this prototype when
users delete the application the error message will be
shown to make the second decision for users.

3.3.2 WatchOS Design Guidelines
In this coursework, watchOS application have been chosen as the secondary control device. To
make the smartwatch application, there are three design guidelines to be followed. Since there is not
coding and only prototyping only one can be applied for this prototype. The applied guideline for
WatchOS will be explained below. (Themes - watchOS - Human Interface Guidelines - Apple Developer,
2020)
Summary
In summary, in this section 3, there have been researched and analysed about the Similar System,
Research about users requirements by making survey and have been set the requirement definition for the
design. All of the these facts will be used to apply for the up coming prototype designs.
In this coursework, the application design will have three main functional features; Connect,
Control and Real Time control (Voice Command). The design for the prototype will be drawn by
following the cognitive psychology of the users, 5 principles from Nelson’s Design Principles and the
iOS and watchOS Guidelines.
However, there will be a few different between smartphone design and the watch design, due to
the smaller screen size the the followed guideline (Glanceable). In the next section there will be shown
about the sitemap for two devices and the low fidelity prototypes drawn by following their respective
design guidelines.
Number Description In detail
Guideline ONE: Glanceable Glanceable means users can use the application short to
the point with showing main information without
distributing by others unnecessary information. Thus to
draw this watch application some of the features
included in iOS app will be removed.
The others guidelines; Actionable and Responsible are not suitable to use for the prototype make.

5. Framework Definition
5.1 Sitemap
Since the prototype will be drawn for two different devices with different guidelines, the sitemap
for these two will be different. In primary device (mobile), users have function like connect and control to
the devices whereas in Smartwatch there will be included only control to the connected devices. This is
because smart watch have the limited screen size and followed design guidelines.

5.2 Low Fidelity Prototype
As mention above, the below low fidelity prototype will be only drawn by following its
respective design guidelines.
5.2.1 Low Fidelity Prototype for primary device (Mobile Phone)
Consistency Design
FIGURE OF WATCH CONTROL BULBFIGURE OF IOS CONTROL BULB
A consistency design isn’t just about using general design icon, design elements, but also the design of
the different devices should be a consistency design. In the above two figures the basic layout, icons and
design elements for two different devices are similar.

Feedback
FIGURE OF DEVICES CONNECT ROOM
Since this is the low fidelity prototype, the feedback show to users clarify, however, if your click
some of the buttons included in the system, it change colour to know what they do.

User Control
FIGURE OF USERS DELETING THE CONNECTED BULB DEVICE
In the figure if users want to delete a connected device, they have been asked whether they want
to delete the derives for sure or not. Thus applying the user control guidelines from iOS devices will make
users to except from dangerous condition.

5.2.2 Low Fidelity Prototype for secondary device (Smartwatch)
Glanceable
 
FIGURE OF IOS CONTROL BULB
As mention above the prototype design of the smart watch is not as same as mobile since it has the
smaller size. From this two low fidelity prototype the design elements of the two devices are similar,
however the layout of smartwatch is different from the mobile one.

Summary
In this section, there have been included about the sitemap to know the process of prototype for
both devices. And then drawn about the low fidelity prototype. By drawing low fidelity prototype the
general layout and design elements used for this prototype have been visualised and the next section,
there will be drawn about the high fidelity prototype based on this low fidelity one.

6. Detailed Design
6.1 High Fidelity Prototype For iOS Application
Before starting about to the home page and the connection page, there need to be an introduction
page for the first time users. Thus they can easily get how to use the smart hub application and how to
connect the application with the hub device.

7. Evaluation
7.1 Cognitive Psychology
7.1.1 Perception
The button of both design have been easily visible and users can notice what is this button means,
especially for Mic icon, users can get used to with voice command button in phone since this is the
similar icon, there will be no problem for users. Thus the design have been proof the perception rule from
cognitive psychology.
FIGURE OF IOS BUTTON DESIGN FIGURE OF WATCH BUTTON DESIGN

7.1.2 Attention
FIGURE OF IOS SELECT DEVICE FIGURE OF WATCH SELECT DEVICE
When users clicked the connected bulb in the bed room, there have to choose which device that
users want to control. The little box will be pop up and get the users attention to get know what to do
next.

7.1.3 Memory or Recognisable
To get the good memory and recognisable design, there need to be a consistency design without
having much layout and design elements changes. In the above figures (shown in attention), both iOS and
WatchOS design are similar with using the similar layout, design elements, background and front colours.
The other pages in this prototype have been drawn in similar ways. Thus users have no issues of
unmemorable between devices or each page. Thus the design can be called as the recognised design rather
than recalled design.

7.2 Design Principle
#1: Visibility of system status
The device selection of the device window is
visibility when it pop up which other background have
been blur. This concept proof that the system was
drawn by following the Design principles analysed in
the previous section.
#3: User control and freedom
When users want to delete the delete confirm
window will be pop up and get the user attention and
asked whether they are sure to delete the device or not.
This is proof that the design have been following the
Nelson Design principles.

#8: Aesthetic and minimalist design
In this prototype design, there have not been any misleading information or words duplication.
All of the features have been place as necessary and only show the necessary design elements. Thus the
prototype have been prove that it is following the Nelson Design Principles.
#4: Consistency and standards & #6: Recognition rather than recall
For both of the design principles have been proved in the above sections. However, the proof
more about that the words are using the standards
words, in the delete window the words of the buttons
have been used cancel and delete and using the different
colours shown in below.

7.3 Survey
After evaluation the design of the prototype with the followed design principles and guidelines,
there have been asked to the users about the how they feel and what is there users experience while
testing the prototypes and the following answer have been answers. People involved in this survey have
been classified by the target users and there are twelve participators have been taken.
Question 1 :
Question 2 :

Conclusion
In conclusion the design prototype have been visualised well by following the users requirement,
design principles, cognitive psychology and design guidelines. In the prototype, there have been some
difficulties to do in some cases, however, the basic process, transactions of the prototype design have
been created.
In the coursework, it had the chance to get know thee things; Number 1 : how to plan for a
prototype design, Number 2 : how to draw high fidelity prototype and Number 3 : how to evaluate after
the design is done.
The main difficulties in making the coursework are the prototyping tools limitations and there is
no background experience of drawing prototyping. Except from this, the coursework have been done
smoothly. Since this coursework have been involved every parts of the process to make a prototype, it can
called the successful coursework and the feedback from the last survey have been positive, thus the
design can be called good design.
