Occupant experience is increasingly playing a pivotal role in both driving innovations and influencing consumers’ purchase decisions. From the invention of electric starters to the dawn of self-driving cars, the prime directive of most of these features has been aimed towards making life easy and comfortable for the consumers. Today, we live in a world where traveling by car may not necessarily always be the most cost-effective choice. However, it is the experience it offers that makes most of the difference.
The consistent shift in consumers’ choices demands a quick and agile response from OEMs, who are primarily focussed on innovations aligned towards their core competencies. Today, much of the trendy occupant experience innovations stem from software and electronics expertise, which typically are the peripheral priorities of OEMs and Tier-1s.
Introduction
Self-driving cars and the idea of level 5 autonomy are no longer concepts limited to the confines of books and silver screens. While there may be smoke of skepticism and appre-hensions afloat, autonomous cars have finally hit the roads. A bulk of what autonomous vehicles do circle around safety and occupant experience solutions. Embedded connectiv-ity plays a decisive role in enabling features that complement and piece together elements that empower autonomy. It can be safely said that the journey towards autono-my is incomplete without supplementing occupant experience solutions.
OEMs and Tier-1s look to take on a force that is not only reconfiguring the value chain but also swinging the market determinants. In this climate, there is an emerging pattern of OEMs and Tier-1s collaborating with ESPs (Engineering Service Providers).
Role of Occupant Experience Solutions inthe road towards Autonomy
We have put together a reel of few case studies related to occupant experience. These files not only highlight the shifting trend towards occupant experience solutions but also underscore the role of engineering service provides in enabling OEMs and Tier-1s to stay on top of their game.

About the Customer
The customer is the vendor of a global Tier-1 company that required an in-vehicle infotainment system platform.
Business Challenge
The customer was fairly new to the automotive electronics segment of the industry and needed a partner to bridge the technology gap. Although the customer had meticulously crafted a roadmap for product development, it lacked the experience in bringing together enabling elements of IoT and automotive electronics together. Another constraint was the aggressive timeline and the budgetary allocation for the project.

About the Customer
The customer is a global Tier-1 supplier of the In-vehicle infotainment solution, along with other multimedia products.
Business Challenge
The customer was equipped with a well-defined roadmap for the development of an info-tainment system compatible with both Android and iOS devices for commercial trucks. The infotainment system solution had to support diverse features like Navigation, Music play-back, Smart connectivity features, BlueTooth supported smartphone synchronization, and others. While most of these features are common in every infotainment system today, the client wanted to launch an infotainment solution with advanced features employing the use of real-time data. This data was required to be fetched via Vehicle CAN and Camera/Sen-sors via three critical Automotive Electronic Control Units (ECU).

Gesture Control

About the Customer
The customer is a technology partner of a leading Automotive company based out of the US. The customer's client wanted to develop gesture controls to enable drivers perform certain tasks without having to take the eyes off the road.
Business Challenge
The key aspect of gesture control is the recognition of images or recordings captured by the camera. Each gesture is identified and translated into a specific command. The high dependency on the identification of a specific gesture requires more than the standard image processing techniques. For this reason, the standard image processing methods need to be backed by machine learning to unfold its full potential. Another criticalchallenge is the prerequisite of eliminating the lag between performing a gesture and its classification.
