Digital services for government agencies, public safety systems, and emergency response platforms.
Bilingual AI Tour Guide: A LINE Official Account for Multilingual Visitor Support
Motor vehicle offices handle a huge range of services. We built a bilingual (Chinese/English) AI guide on a LINE Official Account, using a Retrieval-Augmented Generation (RAG) architecture so foreign residents can ask questions freely in English and get instant guidance on the services they need.
Challenges
- ✕ Foreign residents ask about motor vehicle services in English, and front-desk staff often can't respond in real time, leading to inconsistent service quality
- ✕ Official information and forms are almost entirely in Traditional Chinese, leaving foreign residents unable to find the correct procedures and required documents on their own
- ✕ The knowledge base needs regular updates (regulation revisions, form changes) — using outdated information risks misleading the public
- ✕ Government agencies have compliance requirements for AI-generated answers: every response must be backed by an official source, never fabricated
Solutions
- ✓ A QR code on a LINE Official Account lets residents launch the bilingual AI guide with no app install — just scan and go
- ✓ Built on a RAG (Retrieval-Augmented Generation) architecture: before answering, the AI retrieves supporting content from an approved Traditional Chinese knowledge base, ensuring every answer is sourced, never guessed
- ✓ A Knowledge Asset Management (KAM) module supports version control — once an administrator updates a regulation document, it takes effect immediately, so the AI always works from the latest approved version
- ✓ An Answer Quality Governance (AQG) module lets staff rate and correct AI answers, forming a continuous feedback loop for improvement
- ✓ Full audit logging records every query, retrieval, and answer, meeting government compliance requirements
Outcomes
- 100% traceable answers Every AI response is backed by an official source
- Instant knowledge updates Regulation changes take effect immediately, no model retraining needed
- No download, instant use Scan the QR code and go — no app required
Chiayi DMAT Deployment Inventory System: Digitizing Disaster Relief Logistics
How much medical supply can there be? Not even a single needle can go unaccounted for! We built a three-phase deployment inventory system from the ground up for the Chiayi Disaster Medical Assistance Team (DMAT), integrating inventory in/out tracking, a packing module, deployment templates, and an offline version — dramatically cutting the pre-deployment prep time for the rescue team.
Challenges
- ✕ Supplies span many categories — instruments, consumables, items requiring inventory checks — all managed via paper logs, making pre-deployment searches slow
- ✕ Expiration dates for medications and consumables were hard to track systematically, leaving a persistent risk that expired items went unnoticed
- ✕ Different mission scenarios (earthquake, trauma care, infectious disease response) each required a different supply combination, manually cross-checked every single time
- ✕ Field network conditions during deployment are unreliable, so the system needed to work fully offline
Solutions
- ✓ Phase 1 built the core supply warehouse: inbound/outbound management, a label printing system (paired with a barcode scanner), quick search, history tracking, and tiered expiration alerts
- ✓ Phase 2 developed a packing module and deployment-event system, designing templates for scenarios like intubation kits, trauma response, and earthquake disaster relief — generating a full supply checklist with one click before deployment
- ✓ Phase 3 built a local-network offline version, packaged as a self-contained environment that runs fully on-site with no internet connection
- ✓ Ongoing annual maintenance, continuously refined and optimized based on the team's actual usage patterns
Outcomes
- Phased development Built and refined across three phases, getting more usable each time
- One-click deployment via modules Mission-scenario templates auto-generate the supply checklist
- Full offline operation in extreme conditions Fully functional even with zero on-site network access
Personnel Accountability System
The fundamental difference between public-safety systems and typical commercial applications. Built from scratch: an IP67-rated Beacon hardware device, iOS/Android on-scene personnel tracking apps, and a back-office system, integrated with the API of the National Fire Agency, Ministry of the Interior, and continuously maintained for over five years.
Challenges
- ✕ Personnel arrival, grouping, and entry into the fire scene involve many rapidly changing states, all of which need to be displayed as high-density information in a short amount of time
- ✕ The custom Beacon hardware had to pass NCC low-power radio-frequency device certification and IP67 water/dust resistance testing
- ✕ The system had to integrate with the existing 119 dispatch system, requiring multiple rounds of written back-and-forth to confirm the government API format
Solutions
- ✓ Built custom MIT Beacon hardware entirely from scratch (teardrop shape, glow-in-the-dark coating, hook-and-loop mounting, IP67 water/dust resistance)
- ✓ Developed dual-platform iOS/Android roll-call apps supporting three modes: in-vehicle roll call, on-scene tracking, and full-team wake-up broadcast
- ✓ Built a back-office management system providing a personnel roster, a real-time tracking dashboard, historical record lookup, and report export
- ✓ Got the beacon NCC-certified, successfully integrated with the 119 dispatch API, and passed government stress testing and final acceptance
Outcomes
- 100% MIT Beacon The only Taiwan-made Beacon built to fire-service specifications
- Adopted by fire departments in multiple counties/cities Proven under high-intensity usage conditions
- Visual personnel tracking Intuitive drag-and-drop grouping
Hear AED: Turning LINE into a Lifesaving Tool for Emergency Response
A complex set of requirements, delivered entirely through a LINE Official Account. Since 2022, Emson has worked to improve Taiwan's first-aid environment — from CPR/AED education to information integration — but they were missing an effective, continuously evolving digital tool.
Challenges
- ✕ AED data is scattered across the Ministry of Health and Welfare, the Ministry of Education, and various city/county governments, in inconsistent formats and not updated promptly — nearly 40% of registered locations have devices that are missing or broken
- ✕ Asking the public to download a dedicated first-aid app is itself a high barrier — when an emergency happens, it's nearly impossible for a bystander to already have it installed and know how to use it
- ✕ Verifying a responder's identity/certification involves factors like professional qualifications and certification validity periods, requiring a back office that can keep evolving with new features
Solutions
- ✓ The primary service runs on a LINE Official Account (88% penetration in Taiwan) — no download, no learning curve — leaving the standalone app only for advanced users with specific needs
- ✓ Designed a 'coverage area' and 'on-scene check-in' mechanism, which not only builds trust but also segments and reduces message volume by notifying responders precisely
- ✓ After the core system launched, continued rolling out features like automated tagging, identity verification, and IoT device integration, building out a powerful, highly customized back office
- ✓ Added case details and the 119 case number to notifications, resolving a trust issue and significantly raising response rates
Outcomes
- Lives saved 27 confirmed lives saved
- 19.3% AED bystander retrieval rate improved by more than 15 points
- 11,000+ First-aid cases handled
Mountaineering Safety Tracking Platform: Online Safety Monitoring for Hikers
Integrating the needs of hikers, stay-behind volunteers, and government agencies, using SMS overdue-alert notifications to watch over every person who enters the mountains — built in partnership with the Taiwan Emson Safety Promotion Association and the Taiwan Outdoor Safety Promotion Association.
Challenges
- ✕ Hikers, stay-behind volunteers (mostly middle-aged and older), and the government oversight agency have completely different needs, all of which need to be met within a single system
- ✕ Mountain route descriptions come in inconsistent formats, creating real trade-off pressure between building a standardized route database and hitting the launch timeline
- ✕ Once a stay-behind arrangement is active, the hiking itinerary is racing against time — how do you design an effective dynamic tracking mechanism?
Solutions
- ✓ Hikers fill out a complete itinerary form covering route, party members, emergency contacts, and clothing description, then receive an itinerary code they can share with family
- ✓ The back office automatically flags overdue itineraries in red, letting volunteers log contact status directly in the system — no more managing everything through messaging apps
- ✓ Once the expected return time passes, the system automatically triggers an SMS notification to the emergency contact, with a credit-monitoring mechanism ensuring notifications never silently stop
Outcomes
- Automated SMS alerts Calculated automatically from expected return time — triggers the moment it's overdue
- Dynamic tracking Overdue itineraries auto-flagged in red, so volunteers see status at a glance
- Fully auditable Complete records kept for every itinerary, contact, and alert
Time Tracker: Replacing Manual Clock-Ins with GPS Location Data
Medical institutions have a complex mix of staff — full-time, contract, shift-based — each with different work-hour tracking needs that a traditional clock-in app struggles to handle. This project built a dual-platform app that automatically logs work hours via background GPS, now live on both app stores.
Challenges
- ✕ Researchers' work-hour tracking relied on manual clock-ins and data organization, lacking accuracy and timeliness, and making reporting time-consuming
- ✕ For a typical clock-in app, iOS imposes strict limits on background execution, with complex GPS collection frequency and permission settings — the initial setup flow required guiding users through more than a dozen steps
- ✕ Manually closing the app or restarting the phone interrupts background data collection, often without the user even realizing it, resulting in gaps in work-hour data
- ✕ Development had to span both Android and iOS, while meeting government information-security and acceptance requirements
Solutions
- ✓ Developed a dual-platform Android and iOS app that, once a user logs in, automatically records GPS work-hour data in the background at a 10-minute interval
- ✓ Built a guided authorization flow into the app, walking users step-by-step through enabling 'Always Allow' GPS access and background execution, reducing setup errors
- ✓ A disconnection-detection push mechanism: when data collection is interrupted, the system proactively sends a push notification — tapping it to relaunch the app automatically restores authorization, with no need for a manual reset process
- ✓ A back-office dashboard integrates work-hour statistics, letting administrators look up each employee's GPS location history and background-execution status by account, with support for custom SQL queries
Outcomes
- Location tracking replaces clock-ins GPS automatically captured every 10 minutes
- Individual work-hour records Smart charting, easy to review and edit
- Disconnection-recovery mechanism No data lost on disconnect — a push notification restores syncing instantly
