Reimagining first responder's communication.
R+ is a radical new approach to the communication devices used by first responders during their shifts; it reduces the time, error, and weight added by these devices and makes the most fundamental aspect of their duty - communication - always accessible, easy, and understandable.
The objective of R+ is to reduce the physical weight of existing radios and eliminate the need for extra steps, and limbs when operating and communicating with dispatch.

R+ is a reliable new take on First Responder communication
First Responders make Split Second Decisions
Even small mistakes, inconvenient procedures, or extra steps can cost lives within fractions of a second. With multiple heavy and complicated devices on their bodies, they find it difficult, inconvenient, and time-consuming to juggle equipment in the heat of the moment.
Very Physically demanding tasks
Awkward situation for officers
During Emergencies, it is impractical for officers to lose one of their limbs to communicate (operate the radio), when they could be tending to the situation at hand.
The body is wrapped
Need to bow to speak
One limb occupied
"Current radios are not reliable enough, as they get in the way and unclip easily, be hard to connect with other officers while requiring additional resources to operate - up to a point where first responders sometimes tend to use cell phones to communicate"

First Responders Communication
Instead of having to clip, or be stuffed inside pockets, where the Radio becomes the first to detach from the person of the officer,
R+ softly hugs the officer's neck and can always transmit any command with its flexible body.
Having the radio so close to the mouth ensure better sound quality
Personalized head and shoulder gestures lend R+ to start broadcasting messages to others without the use of hands, helping officers focus better and be more aware of their surroundings.
A simple head tilt, or shoulder shrug will activate R+
Long time Comfort
A day of first responders is filled with a lot of patrolling, waiting around, and low intense moments, with sudden jerks of high-stakes events.
The R+ comfortably sits on the neck, without squeezing the neck, while being lined wth washable Alcantara Fabric.
U-shape flexible form is easy to wear in rush events.
A Flexible construction lends the R+ the ability to securely stay on officers necks during physically intensive activities while being comfortable and adjustable to different neck sizes.
Designed for Duty
R+ is designed for being always present for the officers, while still not coming between them and the task. The compact nature allows it to be worn under uniforms and with other equipments, and also doesn't mess with the hair of women officers.
Easily fits along with and under existing unifroms / equipments.
R+ prioritises the controls most needed by the officers on field like channel and sound control, and provides tactile physical buttons, instead of different knobs, screens and buttons
A single tap to change volume and channels
Quick and easy battery replacement for long shifts. With just a click of a button, and a tug, the battery detaches, allowing officers to replace the radio's batteries within seconds, and go on with their shifts.
R+ is equipped with different features depending on which branch of the first responders they are catering to, followed by other colorways and materials.
The Different colours used in different scenarios
All of the electronic components of R+ are packed toward the back of the body, enabling the body to be flexible where needed.
Used in uneventful patrols
Used during emergencies
R+ completely innovates on the way the radios are used, by taking it closer to the mouth, it makes delivery of cleaner audio more reliable, by using gestures, it makes it more reliable to initiate it without using hands, and makes it more reliable to stay on during high stake events.
Inside surgery rooms
On Construction sites
The Unique form and function of R+ lends itself to be used in a ton of different scenarios everything from inside surgery rooms, helping surgeons stay connected while not using electronics that could fall off easily, to being used in construction areas, where workers usually have all their arms already used up.
How R+ Was
Design iteration leading to final solution
Secondary (Market, Competitor, price, material) and Primary Research
First responder's work involves quick decisions, reactions, and a lot of physical effort
Intensive Physical work
Radios become the best friend for first responders, where staying connected ensure everyone's safety - But using the radio can become cumbersome
Communication is Key to their "survival"
Bulky radio units, fall off during duty - not designed while keeping the officers in mind
Discomfort due to the radio being spread into different pieces across the body
Speaking closely into the mic to deliver a clear message - causing bowing to the mic level
Same motion repeated over and over to achieve a simple task
Main recievers are situated near the waist, forcing officers to hold mic near their head to achieve better signals.
Mic and speakers are often situated away from the mouth of the officer, making sound quality worse
Multiple devices are being used like mobile phones and radios to talk to the same group of people
Only audio is used to notify an incoming message, causing many messages to go unattended.
Insights from the problems faced
by officers through research
"If an officer can't use their radios, then only god can save them"
Reimagining the Radio to fit more seamlessly with the officer's duties
Initial mockup making
The ideation process began with a quickfire sketching session to analyze many radio design options. The research quickly revealed which ideas were worth pursuing.
The Concept was chosen because it was the most reliable and followed the design criteria that were set after the research.
All the chosen designs were modeled first on foam to easily user test them, and then one was modeled in Rhino 3D to give users an idea of the design's potential.
Self -Testing different initial concepts
Headbands seemed promising after a thorough ideation process because they were hands-free, didn't interrupt the user, and were in a prime communication location. A simple model and renders helped the user understand the concept during testing.
Too overcrowded, messed with hairstyles, and applied too much pressure on the forehead.
Headband was a bust...
On reviewing the multiple prototypes created, the chosen direction with the headband was the least liked, with female officers it interfered with their hairstyles, and with male officers, it would put a lot of pressure and crowded the already crowded head area.
In contrast, The Neckband Design was loved by all participants, where even though it was large in size, they liked that it sat loosely on the shoulder and the neck, while it moved with them, not obstructing them, and also helping them not care about the whereabouts of the radio.
...The Neck-Band Design was a hit!
Back to the
With the initiation towards a different direction, the project now demanded many more prototypes to be made for the neckband design. And to avoid the feeling of a very tight fit, many iterations were done, which were immediately tested among close friends and mentors, and with similar scenarios to nail the neck-band form.
Through the simple process of trial and error, the design went from being a very large and loose neckband to something that was small enough to hug the neck softly - while still adhering to the body and moving along with the officers. It also had a similar internal volume as an existing radio to accommodate all the internals.
Back to the
R+ was also shown to the squad of firefighters and multiple security personnel, and it underwent the real test, with different people, different body structures, hairstyles, and use scenarios.
The firemen tried it on with a whole fireproof suit, where the radio properly sat underneath the layers, without causing hindrance to the officers. The unit also conformed with all the security officers' bodies, without causing discomfort, and the risk of falling off. The flexible form conformed to each person's neck comfortably.
R+ still received a few scopes of improvement, where there was still scope to increase the length and make the overall design a little bit more compact, and have different standard sizes.
Had an amazing group session, where they were testing out each aspect of R+
The second edition of the R+ wearable radio system builds from the vast number of iterations done with different materials, and tests with people with different body structures and routines.

Camouflages with the officers day
Having the radio on the neck prevented officers from losing it, forgetting it, or having it dangle off their crowded uniforms.
Previously, a physical button was used to send a message, but now a series of sensors (proximity, force, and gyroscope) embedded in the radio body pick up on slight gestures like a shrug of the shoulder and a neck tilt and start transmitting the message hands-free, giving a physical feedback.
