Prototype demo :

What came about this idea? The idea to design a sustainable technology solution for retail spaces came from my own experiences of frustration and inefficiency in shopping malls. Like many, I’ve wandered through overcrowded aisles, stood in endless lines for elevators, and wasted precious time searching for an available restroom. These moments may seem small, but they build up into a collective dissatisfaction, especially for individuals with special needs or mobility challenges. I realized that there had to be a better way to make these shared spaces more inclusive, efficient, and environmentally friendly.

This solution aims to tackle two significant challenges: congestion in retail spaces and the lack of accessible information about amenities. By leveraging a sensor-based system, we can provide real-time insights into the availability of services like lifts, toilets, or even seating areas. For example, PIR (Passive Infrared) and ToF (Time of Flight) sensors can detect movement and measure distances, giving live updates on congestion levels and occupancy statuses. These updates will empower shoppers to make informed decisions, reducing frustration and improving their overall experience.

Accessibility is another crucial focus. For those with disabilities, having real-time information about available toilets or less crowded pathways can make a world of difference. This solution will help them navigate malls with ease, ensuring a more inclusive environment. It’s not just about technology; it’s about giving everyone the dignity and convenience they deserve when accessing public spaces.

From an environmental perspective, this solution can reduce unnecessary energy consumption. Faulty lights left unnoticed, or air conditioning running at full blast in unoccupied areas, are common examples of waste in large retail spaces. By integrating all amenities into a central Wi-Fi network and monitoring them with sensors, building management can immediately address such issues. Automated alerts and actionable data can ensure resources are used only when and where needed.

Moreover, real-time congestion data can guide mall management in optimizing the use of energy-intensive facilities like escalators or elevators. For instance, elevators can operate at reduced frequencies during low-traffic periods or adjust based on demand. Similarly, lighting and cooling systems in less crowded areas can be dimmed or turned off automatically, contributing to a significant reduction in electricity consumption.

In essence, this project is about making retail spaces smarter and more sustainable. It’s a blend of technology and empathy—creating a system that not only enhances operational efficiency but also addresses the real, everyday struggles of shoppers and staff alike. By reducing frustration, enhancing accessibility, and minimizing environmental impact, this solution can set a new standard for how we design and manage retail spaces in the future. How it works. There are two systems, one for the public and the other is for the management side. Public use :Display screens used to inform shoppers of the occupancy of a certain area. Able to acquire assistance easily through a press of a button. Made to assist those in need, Handicap friendly. Management / Stores use : Able to know number of people visiting the store that day. Able to acquire assistance easily through a press of a button. Able to know whether a fire occurs through ENV display. Has control over Emergency doors. Only those with correct identification are able to access and use this system.
