OGA Internet of Things
The aim of OGA is to enhance the experience of commuting by: INCREASING SAFETY. REDUCING THEFT. GETTING HELP IN AN ACCIDENT.
Modelling FOAM MODELLING was used at the beginning stages of my product development in order to explore form and shape for iteration. This allowed me to make quick mock ups to test in the ENVIRONMENT with the USER and gain valuable feedback.
User Testing CARD PROTOTYPES allowed for testing size of buttons and product with the target user while cycling.
A QUESTIONNAIRE about the models was used with students who commute in uni about theft and accidents to dwelve DEEPER into the PROBLEM.
Modelling my final design allowed for visualising final form and size of the product.
User Interface A phone APP goes in conjunction with the device in order to perform vital functions. It is necessary for the UX to be INTUITIVE backed by a USABLE UI. I developed a PAPER PROTOYPE of potential interfaces for a theft scenario. USER TESTING and ‘thinking out loud’ gave valuable feedback for improvement and come up with a WIREFRAME journey.
‘Icon on the top right is unclear’ ‘Bottom bar can be changed to icons instead of words’ ‘Can I zoom into the map?’
‘It would be good if I can see the address of the location’ ‘I am unsure what the top left icon does’ ‘Can I put the device in lock mode after?’
ArCHAI Reimagining the Toaster
The toaster was reimagined from first principles of toasting bread.
ArCHAI aims to change the way we toast bread with its unique design that allows for bread to drop down as toast on your plate when ready.
This is done with only one twist of a dial at the right texture and colour ready to eat.
Ideation Early ideation explored TOAST JOURNEYS and various ways bread can travel and be toasted by a device.
2D SKETCHES were used for varying shapes.
Development through ITERATIONS explored various forms and shapes as well as mechanisms of heating. Ideas were refined further to develop the final ARCHITECTURALLY inspired form of ArCHAI.
DISASSEMBLY of an existing toaster helped me understand what it consists of and how the bread is HEATED when toasting. Allowing to determine what INTERNALS to use for my toaster. Shiny polypropalyne side panels clip on to frame for aesthetic and heat resistance. Alumium sheet for aesthtetic and cover of internal parts. It is punched and bent around mould when manufactured. Brass Rivets that hold internal parts together.
ArCHAI I needed to consider USER INCLUSIVITY and DIVERSITY as the toaster will be used by a variety of people including challenged users. This was done with intentional CONSTRAINTS in use such as BLURRY GLASSES and GLOVES replicating arthritis.

Cardboard modelling was used for the FIRST ITERATION to explore FORM and INTERACTION.
Sketching different forms over the cardboard model allowed to visualise aesthetics of the toaster more realistically.
Last layer is Mica metal that conducts heat well. It holds and toasts the bread when heating up from the wire.
Plastic buttons for releasing toast and defrosting.
Bamboo legs are more sustainable and easy to recycle while also being aesthetically pleasing. Angled piece is dowel jointed to the horizontal piece.
Polypropylene bottom cover holds bread when toasting and slides out when the toast is ready to drop out.
Dial to set the level of toasting desired.
Outer case is heat insulating metal preventing heat escape. It also holds internal parts together.
PCB board for the controls, dial and general functions.
Nichrome wire layer used to heat up conducting material for toasting.Thicker than n ormal with bigger area meaning quicker toasting.
Main body is injection moulded Polypropylene.
Smaller bamboo leg.
Brushed aluminium side cover that can be taken off if repairs are needed.
LA MARTINA Rethinking horse polo protection
This horse protection was developed for LA MARTINA with the use of their logo and traditional design language. This protection was developed as current offerings in horse protection in polo were only fleece tendon covers that wrap around the legs.
Modelling A full scale CARDBOARD MODEL was made in order to visualise and see the actual form and details of the proposed design.
STEN Charging Pod
STEN addresses and fixes the problem of messy wires by: PROTECTING WIRES FROM DAMAGE. PREVENT WIRES BECOMING HAZARDS WHEN EXPOSED. PREVENTING TANGLED WIRES THAT CAN BECOME TRIPPING HAZARDS.
Research I did both PRIMARY and SECONDARY research to gain valuable information for the development of my charging pod. For primary research I did a QUESTIONNAIRE with potential users and clients about charging devices and aspects of messy cables. I also looked into potential places and spaces my product could be used and measured average student tables and shelves in order to know my size constraints.
For secondary research I looked at costs, materials and dimensions of EXISTING PRODUCTS in order to have an idea of what are the most common materials, sizes and average cost of products in this category. I also went on People Size 2008 software and found ergonomic dimensions and measurements from 5th to 95th percentiles of common grip positions. I also researched into appropriate USB hubs and their prices.
All these measurements are for British males 18-39 years old and from 5th to 95th percentiles.
Summary of Key Findings Primary (Questionnaires and user research) Quantitative: My product has to be able to charge and organize the wires of minimum 3 cables from the questionnaire. The maximum length and width of the product has to be 300mm so it can be used in many areas of the house as I looked and measured the potential spaces my product can be used in. Qualitative:
Thumb-middle finger grip diameter: 42 mm smallest and 56 mm largest.
Square edge grip, thumb-little finger: 126 mm smallest and 181 mm largest.
Square edge grip, thumb-index finger: 101 mm smallest 148 mm lasrgest
The most important aspect of the problem my product has to address is the organization and look of the tidy wires from questionnaire. The place where my product will be most used is the desk and floor from questionnaire. The product has to be minimalist, modern and aesthetically pleasing. The product has to be easy to use and accessible to increase amount of consumers. The consumer ideally has to be able to use the devices while charging. The cables have to be organized and separated so that they are not too close to each other.
Secondary (Market Research and Existing products) Quantitative: My product has to cost less than 80 pounds as the competing products don’t cost more. The maximum length and width of the product has to be 300 mm as most common size for competing products is between 150mm – 310mm in terms of length and width. The places where my product is going to be gripped to pick up have to have a maximum length of 126mm so even the 5th percentile of people can pick it up. With round surfaces, the grip diameter has to be maximum 42 mm. Qualitative: For a better look, I have to use more a mixture of wood and metal for my product. The manufacturing techniques have to be sustainable and environmentally friendly. The materials have to be able to be recycled. The product has to be stable and rigid so it doesn’t easily break and it has to be relatively light so it can be transported and moved around the house easily.
HYPERTENSION MONITOR Telehealth System
The purpose of the system is to provide at home monitoring to people with high blood pressure by:
Making communication between the healthcare professional and the patient easy. Providing vital information when needed as well as monitoring from the healthcare professional based on the readings taken. Showing actions towards high and low readings as well as medical compliance without face to face contact.
Specification Business Context
Cognitive Work Analysis
I used this framework that was developed to model complex sociotechnical work systems.This diagram models different types of constraints that build a model of how work could proceed within a telehealth system.
The NHS Trust is the business organization sponsoring the development of this Telehealth system for hypertension management. Hypertension is a big problem especially in the UK with an estimated third of adults in the UK having high blood pressure without realising it. This system will help the NHS by clearly showing to the patient if they are at risk of developing high blood pressure or if they do currently. Informing this to the patient early on without leaving their home will reduce the strain to the NHS with healthier people and less life-threatening conditions to treat prioritising urgent care and reducing queue times. This system of early information and quick access to help when really necessary will save lives.
Regulations and Standards EN ISO 9000 Quality Management. These international standards are for improving and providing management practices of good quality. Adhering to this standard is a market requirement and will ensure to give a effective and efficient hypertension management system. BS EN 62366:2008 Medical Devices – Application of Usability Engineering to Medical Devices. This is an International Standard that concerns itself with the safety of the medical device through usability. It informs the manufacturer on how to approach usability in this system and validate it.
BS EN 60601-1 Medical electrical equipment – general requirements for safety.
I made a graphical representation of how functions of the telehealth device are linked and work together in this system to deliver the intended goods and services.
This standard refers to medical electrical equipment and the general safety as well as ‘electromagnetic compatibility’ of it.This will help ensure that my medical system is safe to use on a person without causing any harm.
User Characteristics People that have high blood pressure and are prone to it as well as healthcare professionals and care providers that advice these people are the primary users of this system. The patients will in most cases have this blood pressure due to age who are over 65, due to their diet and fitness and due to their lifestyle.This device and system will be used by the patients at home in intervals.The data will be sent electronically to a computer in hospitals through where the healthcare professionals will review the average daily as well as any anomalies and high readings.The professionals will provide necessary personalised feedback back to the patient at home with recommendations of medication and changes in lifestyle.
Analysis Issue Map Issue Mapping gave me a deeper dive into the problem and helped generate new solutions for the device providing feedback. Issue maps are used to integrate problems, solutions and points of view.
Communication Diagram I used this diagram to visualise messages passing between objects and roles that provide functionality. It shows the flow of links and events in this telehealth system.
System Composition Hierarchy Diagram
This diagram helped me breakdown and show internal structure of the blood pressure monitor as well as how each part interacts with each other.
I made this diagram to illustrate the flow of control in this telehealth system and visualise steps involved in the execution of the function of blood pressure monitoring.This is a sequential model that depicts workflows.
Risk Assesment I made an FMEA Risk Assesment to review components, assemblies and subsystems to identify potential failure modes in this telehealth system and their potential causes and effects.This made me think on some improvements and recommended actions to take to prevent these failures.
Device Interfaces I made concept wireframe interfaces for the blood pressure monitor device. Earlier development of the requirement specification and analysis of different diagrams helped inform the features and screens necessary for measuring heart rate with medical compliance.
