Anti-Wandering System: Bluetooth Tracking and LINE Location Lookup for Seniors with Dementia
Estab-Zenith's patented Identity Recognition and Network-Based Location Joint Notification System, showcased through Chiayi City's 'Chiayi Guardian' program. This anti-wandering device and information system integrates BLE tags, a mobile app, a multi-function LINE Official Account rich menu, and a citywide network of checkpoint scanners to build a city-wide walking safety net.
Challenges
- ✕ Seniors with dementia often resist wearing GPS trackers or are reluctant to use them, and the devices require daily charging plus a monthly data plan — a poor fit for their daily habits
- ✕ The system had to serve three very different user groups at once — family members, volunteers, and care institutions — each with very different interface and feature expectations
- ✕ Using a Bluetooth-broadcasting tag for location tracking inherently requires supporting checkpoint devices, while relying solely on the public downloading an app set too high a barrier to adoption
Solutions
- ✓ Adopted a small BLE tag that can be clipped to a keychain, pinned to clothing, or slipped into an ID sleeve — low-power standby lasting 2–6 months, with a user-replaceable battery so there's no need to charge it
- ✓ Partnered with the Department of Transportation, Chiayi City Government to install checkpoint scanners inside traffic-light control boxes citywide, covering intersections across the city to build a citywide walking safety net
- ✓ Launched both an app and a LINE Official Account in parallel, so family members can look up location and receive wandering alerts without ever downloading the app
- ✓ Rolled out a smart roll-call process and a shared-tag SOP for care institutions, so facilities can issue and manage tags in bulk for group activities
Outcomes
- Citywide infrastructure 280+ checkpoint scanners deployed across the city
- Patented anti-wandering system Built a citywide safety net
- Three-layer protection Location, alerting, and search coordination, all integrated
新北幼幼歡樂多語影音秀: A Platform for Registration, Video Showcase, and Online Voting
Built for six consecutive years for the Education Department, New Taipei City Government, this annual event platform for 新北幼幼歡樂多語影音秀 brings together online registration, entry showcases, online voting, and a real-name verification system that prevents duplicate voting — letting the multilingual creations of preschool teachers and children across the city reach a much wider audience through a digital platform.
Challenges
- ✕ The event operates at city-wide scale, with participating teams spanning every preschool in the city — the online registration system needed to reliably handle heavy concurrent usage
- ✕ The voting mechanism needed to prevent vote manipulation to keep the popularity award fair, guarding against ever-evolving vote-rigging tactics
- ✕ The four language categories (Hoklo, Hakka, Indigenous, and English) each have independent judging and awards, requiring the platform to support category-based classification and display
- ✕ After each school year's event wraps up, the platform needs ongoing maintenance and content/feature updates for the following year, adapting to each year's plans
Solutions
- ✓ Built a complete event website with a homepage, online registration, entry showcase, and award-winners pages, fully responsive (RWD) across all devices
- ✓ Developed an anti-duplicate-voting mechanism to keep the popularity award's tally fair, with real-time statistics so organizers can track participation as it happens
- ✓ Built the entry showcase page with filtering by category, search, sorting, and sharing, so parents and judges can quickly find the entries they're looking for
- ✓ Designed the key visual illustrations and site-wide color scheme to capture a visual style that matches preschoolers' lively, playful tone
Outcomes
- City-wide popularity contest platform Uninterrupted registration, uploads, and vote tallying
- Real-name voting verification Effectively prevents duplicate votes and vote rigging
- Embedded video playback architecture Reduces platform bandwidth load and improves playback stability
Wunfu Elementary School: Green Mobility in the City — A Plastic-Reduction Guide Built by Students
High-quality low-carbon travel content, created by a group of elementary school students! The site brings together five student-designed routes, must-see stops, and a bilingual map of plastic-reduction-friendly businesses — blending local history and culture to turn classroom action into a public-facing digital platform.
Challenges
- ✕ The coursework produced a wealth of material — route plans, business-visit records, video content — but it was scattered across different media with no unified digital front door for the public
- ✕ Plastic-reduction-friendly business data needs ongoing long-term maintenance, so the site had to flexibly accommodate changes as that data evolved
- ✕ The site's audience includes international partner schools, so it needed bilingual Chinese-English presentation, with a visual style matching the lively, playful tone of the students' work
Solutions
- ✓ Adopted a Vue.js + Nuxt.js + Vuetify front-end framework with responsive (RWD) design, ensuring a consistent browsing experience across every device
- ✓ Integrated YouTube video embeds, student-shot photos, and route/attraction information, so every route comes with complete digital guide content
- ✓ Designed a bilingual Chinese-English plastic-reduction-friendly business map, with a back-office data update mechanism so business information can be adjusted directly whenever it changes
- ✓ Deployed on a Google Cloud Platform server in Taiwan, reliably handling traffic demands during the campaign's promotional period
Outcomes
- Travel video platform Five low-carbon routes, fully presented in video
- Interactive map 38 plastic-reduction-friendly businesses listed in Chinese and English
- Easy to maintain Clean data design supports Excel import
