EXPERIENCE DESIGN
ConnectNeXT : Smart car ecosystem for Tata Vehicles
How can you improve customer's information experience of the car?
INDIGENOUS SMART-CAR PLATFORM FOR INDIAN AUTOMOTIVE MARKET
ConnectNeXT is a infotainment and telematics platform developed by Tata Motors Research with my
team. It allows
users to interact
more immersively with the car, provide actionable data insights, and stay connected with the brand.
The
work involved
design, development, and testing of six android apps. These apps allow users to control the
infotainment system, troubleshoot common vehicle problems, improve driving with data, get assistance
in case
of an emergency, and share music
inside that car.
The major Apps I worked on were:
- Drive
Next
- Juke
Car
- Smart
Vehicle Manuals
- ConnectNeXt
- Emergency
Assist
- Remote
Control App

Context
This is 2014, Vehicle infotainment systems are getting computation heavy. The
customer demands more
connection and driving needs to be data-informed (driven). The competition has some derived
solutions in the market. We
needed to respond by building our own telematics solutions based on regional customer habits. I was
involved as a Lead
from PAT (Performance Attributed and Targeting) side in the
project when the dev and design already had some ideas and had some prototypes being tested. PAT is
a group that is responsible for customer
experience and works with Design on new products. Tata
Motors follows a mix organization structure adopted
from JLR and essentially Ford.
My
task was to rethink and
improve the project – ConnectNeXt, from a user-centric point of view. It is one of those
projects,
you are on the team
and have to fight for the user. Then not be lured by the cool technology that could possibly take
too much attention
while driving. Not making an App need attention was the task. Android auto was still very new in
the market at that time.
Work
I worked with many design and dev teams (across 3 companies) in my role for
the project. We
studied the designed screen and flows. We did reviews of iconography, typography, and information
architecture.
Nitpicking things and presenting the user’s point was the goal. There were experiments to make apps
that would adjust
the visuals to the time of the day. The interaction points in the app were designed to be operated
in a road filled
with potholes.
We simulated this condition using a torture track. This helped us move
critical/decision points outside
the primary interface area. We researched about in-vehicle safety. Safety is at the top while using
such
apps in vehicles.
With some benchmarking data, our user studies, and simulations, we designed some rough guidelines
for vehicle-based
apps on TML platform. The idea was to have a central/mother-ship app that auto-configures based on
the vehicle
it is connected.
The
app would suggest possible compatible apps from the ecosystem. Then, it configures them. This is
the connectNeXt app.
About 150+ use cases were to be designed, implemented, and tested. Once the interface layer of
these apps was sorted as
a system, we moved on scoping the feature matrix. The entire operation was based on the Smartlink
protocol stack, and
hence we worked with a lot of connection, re-connection, and disconnection use cases over Bluetooth
and/or USB. All
these apps are now in the play store. 🤓
Below I present briefly the apps and the use
cases they
cater to.
DriveNeXt: Helping users drive better
DriveNeXt app gives driving behavior analysis and suggests improvements. It
runs
algorithms tuned by
Tata Motors Driving Team. The App presents
users with insights into their driving habits. They can choose to drive for improved mileage or
performance. Users are explained possible action points
they can include that could get them a better outcome.
JukeCar: In-car Music Sharing
JukeCar is a music sharing app to make collaborative playlists when many
people travel
together in a car. Indian customers love to listen to music on long or group journeys. With means
of carrying music becoming more
mobile, it became difficult play requests by each passenger from their phones. The users had to
disconnect bluetooth and reconnect it again to a different device or switch cables. This app tried
to solve
this issue by allowing a device connected to the Infotainment accept music as streams from other
device over WiFi.
Smart Guides: Smarter automotive manuals
Smart Guides is a life saver if you are looking for information about the car and do not have the
manual at hand. In automotive industry, the car manuals
are getting more complex due to the amount of new things that are possible with cars. It is also
common for people to not carry them. Even if they have it, the
amount of information is too much to process. So, we worked on a smart manual app that lets user to
not only search the car manual but also give a place to store
important information about the car like car chassis number, insurance and driving license number
for quick reference. This app becomes an important
touch-point for prospective customers to know about the car before visiting the showrooms.
ConnectNeXt: The mother-ship app
ConnectNeXt allows the user to configure the Tata App ecosystem with her car. The App has been
designed by our team to make the process of configuring as
easy as possible. The App talks to a couple of ECUs in the car via the infotainment and identifies
the car variant. Based on this identification, it shows the user
the apps that she can use. The users can install and configure other apps using this mother app.
Emergency Assist: The help when you need it
Emergency Assist is a safety app that detects crashes via crash sensors and sends SOS messages to
emergency contacts. The app allows users to configure the contacts and help the family track the
car. The user can optionally trigger an emergency too.
Another unique feature of the app is to make the phone act as a beacon. The app emits audio and
light beeps to find a car in an emergency. This
could be useful during search and rescue operation.
Remote Control : So you can sit back and relax
This app caters to another unique Indian use case. How can I change the cooling levels from the
rear seats? Or how can I operate the infotainment
unit without disturbing the driver? These use cases are especially important in chauffeur driven
cars. Remote control app allows users to control the audio and cooling system from the phone. These
two were
the most commonly requested changes a users asks the driver to perform.
Learnings
This was one of the things, I am kind of proud of. A lot of things come to light when thinking as
the process. The API
calls, UI layers, car data, user privacy, variable in a car, no internet, failure cases, and
finally edge cases. I
learned things like JIRA, App Ecosystem, CAN Tools, Vehicle Diagnostics, Vehicle safety, process
maps, and doing
projects with a lot of different stakeholders. The testing part of the project was fun.
Initially,
we were all
communicating by logging bugs in JIRA. I did not even know people by their faces, just by their
JIRA user names. But
later, It was getting difficult to explain some very typical use cases. So, we decided on doing
extensive all day
collaboration drives with stakeholders. I used to drive in Pune and neighboring cities. We were
logging data and
simulating events, with the app developer and infotainment developers sitting in the car. They were
initially scared of
sitting in a camouflaged car. But, we were fixing more than 20+ bugs a day. I won an award for my
work with the project
too.
I further learned how to manage project timelines and plan them well. It taught me the value you
get when you work in a multidisciplinary team.
How it affected the company
I feel, it laid the foundations of what ConnectneXt is today. The company position transformed from
being competitive
in the market to become market leaders. The best part was all the tech and design was in-house and
the company can
virtually do anything the customer needs without sticking to the excel-sheet approach of many
suppliers.
