• Problem: People run out of basics (soap, shampoo, detergent, cooking oil, etc.) and rush to buy new plastic bottles every time → waste of money, plastic, and effort.

• Solution: A network of smart refill stations placed in apartments, campuses, and local stores.

  • Customers bring their own reusable containers.

  • Scan QR code → choose product & quantity.

  • Pay digitally, refill instantly.

• Tech Angle: IoT-enabled dispenser tracks usage, prevents spillage, and sends alerts when stock runs low.

Market Gaps:

• Current refill options are rare, limited to niche eco-stores.

• No tech-driven, convenient system for students, hostels, and busy professionals.

• Most sustainability solutions focus only on recycling, not on reducing single-use plastics at source.

Who Benefits:

• Students & working professionals: Save time + money on small, frequent purchases.

• Retailers: Cut packaging costs and attract eco-conscious customers.

• Community & Environment: Huge reduction in plastic waste.

Why It Matters to Me:

• I’ve seen my hostel dump dozens of shampoo/detergent bottles every week.

• Small changes at campus/community level can scale massively if made convenient.

• It connects with my interest in tech + sustainability → solving a real problem I live with daily.

One of the most common struggles I’ve seen as a student is simply finding my way around large campuses. Google Maps helps outdoors, but the moment you step inside a building, its usefulness ends. Freshers often feel lost trying to locate classrooms, labs, or administrative offices. The same happens in malls—hundreds of shops spread across multiple floors, but no easy way to find the exact store. That’s the gap I want to solve with CampusMaps: a mobile app that extends navigation indoors.

The concept is simple but powerful. Using only the phone’s built-in sensors like the accelerometer (for counting steps) and gyroscope (for direction), the app can estimate your movement and guide you in real time without relying on Bluetooth beacons, Wi-Fi routers, or any extra hardware. Just one tap, and CampusMaps becomes your personal indoor guide—pointing you toward your lecture hall, the library, or that café in a crowded mall.

The benefits are huge. Students, especially newcomers, gain confidence and independence navigating their campus. Shoppers save time and stress when locating specific stores. Universities and mall managers benefit too, since happier visitors means smoother operations and better experiences.

This problem matters to me because I’ve personally experienced the frustration of being lost in a new campus. What should be an exciting first day often turns into stress and confusion. With CampusMaps, we give people not just directions, but freedom, confidence, and time saved.

Of course, there will be challenges—accuracy, data mapping of interiors, and UI design—but if solved, CampusMaps could redefine how we navigate the world indoors.
