Exhibition Kiosks: Why the Screen Matters More Than the Hardware
A line forms at the info desk within an hour of doors opening. Booth location, restrooms, next session time, the same three questions on repeat. Organizers install a kiosk expecting that line to disappear, and sometimes it does. Just as often, a visitor taps around for ten seconds, gives up, and walks straight back to […]
Digital Stamp Tours for Exhibitions: QR Instead of Paper Coupons
A stamp tour at a trade show takes a surprising amount of setup. Coupons get printed. Ink stamps go out to every booth. Someone installs a collection box near the exit. Then the event ends and the real work starts: counting. A digital stamp card fills in as visitors scan each booth’s QR code. QR-based […]
Exhibition Business Matching Software: Replacing Spreadsheets and Google Forms
Buyer applications land in a Google Form. Matching happens by hand in a spreadsheet. Schedule changes get confirmed over phone calls and text messages. A lot of organizers still run exhibition business matching exactly this way, and it holds up fine until the exhibitor list crosses about fifty companies. Past that, the spreadsheet stops being […]
Indoor Navigation Software: A Live Look Inside COEX, Kolon Gyeongju, and Oakwood
A visitor walks into a 100,000-square-meter exhibition hall holding a folded paper map. Within four minutes, most people give up on it and start asking staff instead. That single moment, someone standing still, phone out, unsure which hallway leads where, is the entire market for indoor navigation software in one picture. GrowSpace’s exhibition wayfinding kiosk, […]
RTLS System Buying Guide: What to Check Before You Sign a Contract
A practical checklist for evaluating an RTLS before you buy: technology choice, real-world accuracy vs datasheet accuracy, tag economics, and integration.
How to Use a UWB Tag to Read Its Position
A UWB tag works out its own position. The anchors do not compute a coordinate and hand it down to the tag, and once that direction is clear, so is the question of where to go looking for the numbers. On the developer tag in the GrowSpace Creator Kit (Q1), they come out over serial. […]
Custom Exhibition Kiosks: Building Software for a 60-Booth Public Expo
How GrowSpace built recommendation software and six rented kiosks for a large public-sector expo with 60+ booths.
How Many UWB Anchors Do You Need? (2D vs 3D)
You mapped the space, picked your tags, and now one number is holding up the whole order: how many anchors do you actually buy. Buy too few and the position never resolves. Buy too many and the extra hardware just sits in a drawer gathering dust. This guide hands you the number, the reason behind […]
Build Your Own UWB Setup, or Buy a Kit? An Honest Guide
You want centimeter-level indoor position, and you’ve hit the fork every maker hits. Buy a finished UWB dev kit, or wire up a few cheap modules and build your own? The parts for a DIY rig cost almost nothing, and that single fact, more than any spec sheet or shootout you’ll read on a forum, […]
UWB on Raspberry Pi: Reading Indoor Coordinates with Python
GPS falls apart the moment you push a robot through a warehouse door. Satellite signals don’t get through roofing and steel, so the coordinate that looked solid in the parking lot starts drifting the second you go inside. Wi-Fi and BLE trilateration will hand you something, but it wanders by three to five meters. Fine […]
