Hi I’m a product and brand designer from Toronto who recently graduated from York University/Sheridan College Program in Design YSDN. I enjoy examining how design can assist areas of need, simplify problems, and craft smarter and safer experiences. Outside of design, you can find me checking out the latest food craze and places, and scouting out shiba inus on the street.

Oble: The Smart Inhaler


Asthma is one of the most common chronic lung disease among children. Poorly controlled and undiagnosed asthma can result in trips to the emergency room, hospital stays, missed workdays for parents and suffering that many children can’t express. In addition, the process of asthma treatment is complex. Using an inhaler can be daunting as it is very specific, has multiple confusing steps, and unusual breathing technique uncomfortable for young users. This results in only 50% of users knowing how to use inhalers properly. If this is the main method to treating asthma, and a large percentage of kids do not know how to use it properly, how can we simplify the process and make it more understandable?

In Canada, roughly 600,000 children under the age of 12 are affected by asthma and even with multiple solutions, only about 50% of them know how to use their inhalers properly.

— Oble


Oble is an easy to use, friendly, smart inhaler designed for children that combines the standard inhaler with the spacer into a single product. With it's companion app, Oble can help assist children taking their medication more efficiently without any prior assembly, and is embedded with Bluetooth technology that allows parents to track the device's usage and how well their child is doing every day.


To develop a better understanding of the challenges and struggles that accompany asthma, we wanted to hear from those who experience close interaction with it. Those such as parents, pharmacists, doctors as well as other individuals who have been effected by the issue.

From these small interactions, we gained valuable insight into the daily struggles of parents or caregivers faced with having and caring for those who have asthma. After consolidating our findings from our user interviews, secondary research, and our competitor analysis, our team created a pact analysis and user personas to better illustrate what we are dealing with. This ultimately helped us pinpoint what the current market was lacking, as well as what we can do to create a better solution.


While building our product concepts we also started with building our brand including colour palette, typography, 3D modelling, illustration style, icons, and brand values for our product.

With our product targeting a younger demographic, we wanted to create a friendly and approachable application that kids would love and parents could trust. Thus we incorporated light tones of blue and coral, soft and playful illustrations, and made it as simple as possible to make the user feel at ease.


After multiple iterations of sketches and prototypes—as well as receiving feedback from our peers, parents and professors, we collectively finalized a product design that ultimately targets all of the problems areas that we wanted to resolve.

Next step was developing concepts for our product while keeping our target audience in mind. Initially, our design had a generic tube shape for the inhaler but after some feedback, we started exploring designs that are friendly and something kids would love to carry around with them.

Mobile App

After solidifying the physical product, we started with prioritizing the core features of the apps. We went through multiple iterations and also did some in-class tests to validate.

Final Product

Our final product has a friendly tone and the removable silicon characters allow children to use their asthma medication without worry of being looked down upon. Instead of being embarrassed about having asthma, they can get the right treatment confidently, whether at school, home or anywhere else they go.


We wanted to make the product more appealing for kids to carry Oble around with them at all times. We already had the option to replace the body with replaceable silicone animal sleeves, so we added the option to add stickers to make it more personal.

Oble App

The Oble companion app is designed for parents to help administer their child's health. By tracking their breathing efficiency (tidal volume) with each use, the app also offers breathing practice exercise to help getting better with using Oble, or if the child is having any problems. A report can also be exported as a document to share with their doctor.


Simple and delightful user experience for first time users when pairing their Oble with the app and creating their child's profile.


Information on different sections help users with getting familiar to the different features that the app offers.


Easily compare weekly and monthly usage with detailed reports. Tracking the number of usage, can help caregivers understand the severity of asthma better.

Breathing Practice

Oble measures the volume of air that is inhaled with every use. This helps with tracking child's breathing efficiency with every use. Whenever the child is having problems using the device, caregivers get an alert so you can practice with them.


This was one of my favourite projects that I’ve gotten to worked on in my academic years. This project really taught me the importance of collaboration in a team setting. Common from different skillsets and experiences, we were able to rely on one another in situations where we lacked abilities, and hop in when our skillsets shined most.
