HOW 

 

How can we use sound and light to create a self explanatory auto-injector for people who have severe allergy?

 
 

 

MEET ISA10

 

ISA10 is an Epinephrine auto-injector for severely allergic patients. It uses sound and light as a language ,which guides users trough the whole process to help them use it correctly. Additionally it calms down the users and improves their usage experience. ISA is a tool and a companion which accompanies the users all the time, allows them take the ownership of their allergy, as well as reassures that they will be fine.

CHALLENGE

 

Use sound and light to create a self explanatory auto-injector that guides users through the whole process to help them to use it correctly and help them calm down.

 
          Hard to find

Hard to find

         HAVE TO KEEP AUTO-INJECTOR WITH THEM

Existing products are huge and scary

        MOST OF THEM MISUSE THE AUTO-INJECTOR

84% of Patients misuse

 

SOLUTION

 

A pen for auto-injection which provides sound and light feedback to guide the users through the whole injection process. Sound and light design were built around the metaphor of a flowing liquid. They influence and coordinate with each other, and help users to understand how to use it correctly in emergency situation .

KEY FEATURES

 

1. Easy to find it

Because of the emergency situation, it’s crucial for the users to find the auto-injector as soon as possible. The Auto-injector alarm and the flickering light helping to find the device can be triggered by one click in the application or strong shake of the backpack.

 

 

2. Alert the user when the injector is ready

Since the user might not always be experienced with auto-injectors, there are sound and light feedback when removing the cap. They happen at the same time to indicate the injector is loading. This is a good way to show that ISA is safety and ready to use which can smooth the whole using process. 

 

3. Display the 10 second loading process

The most crucial part of the whole using process is the 10 second loading period. The user needs to remember to hold the injector on his thigh for at least 10 seconds after triggering. We created a set of sound and light feedback that guides users to keep injector on his legs and remove it when the injection is finished, especially during such emmergency situations.

 

 

4. Contact the nearest hospital after an injection

The emergency system will connect the user with the nearest hospital after every injection to make sure the user will be fine when they have serve allergy reaction.

 

Process

ISA10 was the result of a ten day collaboration with the MFA of Advanced Product Design at UMEÅ, Institute of Design part of the course "Industrial Sound Design".

OVERVIEW

The project was a two week collaboration with one student from the MFA in Advanced Product Design. The short timespan made the process extremely high paced. So after we had developed a common vision regarding feedbacks and the user experience we divided the task. The interior and exterior of the auto-injector, sound and light design were built simultaneously, we still had to communicate a lot.

 

DESIGN QUESTION & IDEATION

We start from allergy, and looked for specific potential situations where sound could be utilized. Afterwards we decided to focus on the severe allergies and the auto-injector,. Then we identified the design problem, and made sure both interior and exterior design are on the same page.

 

SOUND SKETCH

We created a sound board and designed specific sounds for each step. Sound design inspired from the metaphor of the liquid flowing out of the device. The goal of sound design is using clear sounds with liquid associations to mimic the fact that liquid is injected into your body.

PROTOTYPE & USER TEST

In order to make sure that the feedback can guide users properly , we built a prototype to demonstrate the changing of light and sound. Thanks to that the users can intuitively understand our design, and gave us insight into the problem, and help to improve our final solution .

 

TANGIBLE PROTOTYPE/

 

The final prototype uses an Arduino Nano for main logic, and an Adafruit Audio FX Sound Board connected to a small speaker for the sound. In order to make the real injection experience, we used a plastic tube taped with slim rings to fake space between LEDs, and make it easier for the users to understand the functions of our design.

 
 

USER TEST

We conducted two research studies. In the initial research, we explored the possibilities of light and sound guiding the user through the injection process.  After we improved the sound and light design and made the prototype, we conducted a research study using the Wizard of Oz methodology. Thanks to that we realised that first time users are able to perform the task correctly meaning, which means our solution is understandable without detailed instruction. 

 

FORM

The form so the device is intended to make injectors appear less intimidating and easy to use. To make ISA more personable and reduce the cost of production, we decided to make the part that holds the electronics reusable while piece with the needle and medicine is disposable.

BRANDING & APP UI

We designed a simple app that can helps users find their devices and contact the hospital after an injection. Additionally, we worked on the branding which includes a logo and a package.
