Ever heard this type of conversation? Novel drivers face lack of confidence, making quick decisions while behind the wheel as they are new to the world of driving. So they rather prefer to sit in the back seat or use other modes of transportation.


This state of uncertainty might lead to chronic road accidents in which the individual copassanger as well as the other party could be injured resulting in temporary, permanent disability or even death. But this risk could be prevented provided with the right direction to these audiences.


Thus C.A.N.D.Y.(Capability Assistant for Novice Drivers Yaw) is a smart assistive system to enhance confidence for novice drivers who get conscious and clueless on roads during the initial days of driving.


Covid 19 has affected human life in many ways. Transportation is also one of them. The pandemic led to a type of insecurity among people’s minds while travelling using public transportation. Here are some statistical data

The largest decrease was seen in the modal share of metro services (9 %) followed by buses (4 &), and local trains (1%).

A significant increase in the private modes of travel. The share of private cars and two wheelers increased by about 10%.

Group 53.png

People started inclining towards private mode of transportation i.e. 4 wheelers and 2 wheelers.

Comparative stated mode share.png

But what's new in it?

Unlike the previous time, this time the inclination towards 4wheelers was purely driven by the need of the moment not by the want.


This inturn caused a necessity to drive by oneself.

Secondary Research

Road accidents
ResearchAsset 21.png

As per the World Health Organization, accident related deaths are known to be the eighth leading cause of death and the first largest cause of death among aged 5-29.

ResearchAsset 31.png

In India alone road accidents kill almost 1.5 lakh people annually. Accordingly, India accounts for almost 11% of the accident related deaths in the World.

Govt. of India recognised human error as one among the 3 major reasons for road accidents

Modal shift in transportation

increase  in the share of

The decrease in public transport is mainly compensated by an increase in the use of private vehicles.
Owning a personal car is one side, making it run is also equally important; Either learn by oneself or hire someone to drive for you.
Further, this creates a situation where not knowing to drive a vehicle makes a person immobile, Hence making him/her disabled to move when it is necessary.

So what makes practicing driving difficult?

Key findings


Studies concluded that driver education and training contributes little to reducing crash risk or involvement for road users

Driver training programmes on vehicle handling skills may actually lead to increased risk taking due to learners’ inflated self confidence and self-rated skills.

Monitoring the capability of what they can do and modifying their learning strategies appropriately; A self assessment.


Emotions, mood and mental stress may affect driving-related performance in a number of ways, leading to risky and aggressive driving.

The lack of adequate skills is not so much a matter of poor vehicle control, but is more a lack of: 

  • ​being able to observe properly

  • adequately judging traffic situations

  • predicting accurately how a particular traffic situation will develop.

 It is also important for a novice driver to understand his capacity; E.g. ‘it is dark and raining, and as I don’t have enough experience yet, I will go by Taxi this evening and not by car’

Primary Research

I conducted primary research to know the actual situation. The research was conducted in local driving schools and was conducted among some users of the age group 18–35 years. It included

  • One who is learning driving

  • Learnt but not practicing

  • Learnt and practicing

  • and the Pros

Driving school instructors' perspectives 


I take 2 to 3 theory class on basic road signs and basics of car and proceed



It is difficult for those who don't know anything about car



Normally 30 class of 5kms each should be enough to learn to drive.(ONLY LEARN)



Unable to explain the dynamics of a vehicle



No feedback system for  tutor



No validation for learner that how much he/she learnt 


User observation

With the permission of the driving school, I affixed a camera on the dashboard and sat diagonal to the learner while he is driving so that I can observe him/her closely.

Smart band experiment 

Further I requested the participants to wear a smart-band so that I can measure the approximate driving stress.

I was able to find out that Learners tend to make more mistakes under stress. Also while under stress giving them more input intern increase the stress level.

A checklist was developed based on the observation while a learner is driving the car. The updated version later compared with the existing driver evaluation checklist form to validate the credibility

"Learning to drive was always a dream for me since childhood. Now I can drive confidently and don't require help unless I get stuck in a parking lot or sometimes changing the lane. Then I get panic and won't dare touch the car for a week."

"I decided to learn driving as I thought public transport wouldn't be safe considering  the present covid and social situations. Now I have the hold of ABC and steering. The problem is I can observe surrounding but I'm not able to act accordingly. There should be some help during such a situation."


Shraddha K

26 years, Project Management consultant 

"The biggest barrier for me while driving was my inner fear itself rather than any external factors.  The stress while driving also leads to fluctuating pressure on A-B-C. I can’t deny the fact that driving school did help me; however, it is always the standard one. I couldn't get personalised instructions."



I get distracted when I see vehicles.

Finalising the parameters

The parameters were first divided into 3 main phases to emphasise on the actual problem. Further filtration was done based on the relevance and learners tendency to not do the mistake

Design Brief

To design an assistive system for novice drivers to enhance their confidence while driving


A multimodal assistive system for novice drivers while they drive .



By aiding aiding the capabilities i.e motor, sensory and cognitive


To enhance their confidence thus reducing dependence on other individuals 


I tried to ideate a device inside the car. To introduce a new device to the ecosystem of cars it was necessary to study the ergonomics of the car.

Phase 1 ideation : Preliminary 

In the initial phase of  ideation, Sensor based tracking and Feedback system were given more importance as it would mostly solve the stated issues.

Phase 3 : Combine
Final ConceptAsset 1.png

Picked concepts from the previous ideation are developed and consolidated to form a multimodal assistive system. The system uses connected car technology to communicate bidirectionally allowing cars to receive and share data with other cars and other available IoT devices. The finalised concept consists of 

  1. Hardware. (HUD unit and Responsive steering wheel upholstery)

  2. User Interface

  3. Smartphone application

Final Concept

Identity design

C.A.N.D.Y. is a multimodal assistive system for novice drivers to enhance their confidence and driving skills both on and off the road.

C.A.N.D.Y. stands for Capability Assistant for Novice Drivers Yaw, where "yaw" is a term used in aviation symbolically used to signify the ability gained by the user after utilising the product. Also Candy, a type of sweet signifies as self rewarding for user's achievement.

Logo is developed using the combination of a Candy and a Gear lever enclosed in a circle indicating proper use of control leading to an instant result.

Head Up Display Unit 

A dedicated head-up display unit to project the real-time visual feedback to the user. The unit further consists of configurable buttons which can be set according to the user's need.

In addition, the unit is equipped with a smartphone docking space, thus strategically avoiding the usage of phones while driving.

Okay. Now I learnt to drive. What next?

Once the user is confident enough, the feature will also evolve accordingly. The whole system will turn into a vehicle maintenance companion thus a turn the user into a tactical driver

Good driving habits 

Compulsory implementation of the system will create better awareness of good driving habits resulting in reduced traffic.


Old-age community

This could be a boon to older audiences since their driving performance may decline with age.


Reduced road accidents

Safe driving habits and assistive technology will drastically reduce road accidents, if not at least will lower fatality.
