Hong Kong Case Study · AI Interaction Wall
A school corridor becomes a trilingual AI speaking wall
In Tai Po, a Hong Kong primary school converted an ordinary corridor into its 「普通話學習廊」 — a Mandarin learning corridor: one 55-inch AI digital human flanked by nine customised hexagonal frames. Pupils ask in Cantonese; the wall answers in Mandarin or English. Delivered on site by Decatron, WEEEMAKE’s Hong Kong integration partner.

01 · Hong Kong at a glance
Five schools, six wall environments, one modular system
The same hexagonal system has been re-skinned for very different rooms: a language corridor, two AI exploration stations, a computer room, a darkened science lab feature wall and a blue science zone. What changes between sites is the wall graphic, the frame mix and the content language — not the hardware.
The local constraint
Three spoken languages, two written ones. Hong Kong pupils think in Cantonese, read Traditional Chinese and study English as a core subject. Every frame on this wall therefore runs a Traditional Chinese interface and can answer in Mandarin or English while accepting Cantonese questions.
Off-the-shelf English-only AI exhibits do not survive this requirement — localisation is the real work.
How it ships
Manufacturer plus local integrator. WEEEMAKE supplies the hexagonal interactive frames and the AI content platform; Decatron handles the wall graphic design, the on-site installation, content localisation, in-school AI lessons and after-sales support.
Schools coordinate with one local team instead of chasing an overseas supplier across a time zone.

Project scope names follow how each school and Decatron describe the installed work. Two of these sites are STEM or joinery walls rather than AI language walls, and they are labelled as such: the featured AI language wall is the Tai Po project below.
02 · The featured case
From a spare corridor to the school’s Mandarin speaking lab
The project brief states the core idea plainly: get pupils talking on their own initiative, inside a relaxed game-like atmosphere. Every frame accepts a spoken question and answers aloud, so speaking practice happens during break time, not only in timetabled lessons.

01
Brand the wall, do not just mount screens
The graphic is a deep-blue tech treatment built for this school: binary digits, circuit-board texture, a line drawing of the school building, the school’s glowing “TPOMPSPC” lettering and its mascot characters. Pupils recognise the wall as theirs before they touch it.
02
Use the corridor you already have
No room was sacrificed. A circulation space became a self-service learning environment that stays open during breaks, parents’ days and open days — which is where a STEM purchase gets justified in the eyes of the rest of the staff.
03
Make the content owned by the school
The digital-human avatar, the knowledge bases and the quiz banks are all school-editable through the backend. One frame is dedicated to school history and Tai Po district culture, so the wall grows with the school instead of ageing out of the curriculum.
03 · Anatomy of the wall
A “1 + 9” layout: one presenter, nine exhibits
The nine frames are mounted in honeycomb clusters of three on both sides of the central screen. Each frame carries its own display, microphone, speaker and RGB light border, and works independently — a pupil can be mid-conversation with the digital human while two others run a quiz at the far end of the wall.

AI
Voice AI large-model frames
The core of the wall. Pupils ask freely in Cantonese, Mandarin or English about the frame’s theme; a large language model answers aloud in Mandarin or English. Real objects and models are displayed inside the frame, so an abstract answer has something physical next to it: a Tiangong station model, movable-type blocks, real butterfly specimens.
MAP
Voice smart-map frame
A world-map display combined with voice interaction. Pupils ask where a country is, what language is spoken there, and about its culture — which turns geography into language practice, because the answer comes back as spoken Mandarin or English.
QZ
Science quiz frames
The teacher writes the question and four options in the backend; pupils answer on four physical buttons — red, blue, green and white for A, B, C, D. Two modes are built in: a study-practice mode for self-paced exploration, and a speed-challenge mode used for inter-class competitions and activity days.
04 · The nine frames
School-based themes, not a catalogue drop-in
None of these nine frames is a stock theme. The school chose the mix and the content was built around its campus, its curriculum and its district — which is the difference between a purchased exhibit and a space pupils claim as their own.
| Frame | Type | What is inside, and what pupils do with it |
|---|---|---|
| Voice smart map語音智能地圖 | Voice smart map | World-map interface. Voice queries about the location, languages and culture of countries and regions, so geography is practised in spoken Mandarin or English. |
| Tiangong space station天宮太空站 | Voice AI large model | A model of the Tiangong station sits inside the frame; pupils ask about China’s space programme and orbital science. |
| Dinosaurs and palaeontology恐龍古生物 | Science quiz | Four-option dinosaur quiz answered on the physical A/B/C/D buttons; the question bank is teacher-editable. |
| Movable-type printing活字印刷 | Voice AI large model | Type blocks on display, with voice Q&A about the Four Great Inventions and Chinese writing culture. |
| Sichuan opera face-changing川劇變臉 | Voice AI large model | A face-changing puppet behind a transparent display cover, with voice Q&A on traditional Chinese opera. |
| School and Tai Po culture學校及大埔文化 | Science quiz | A school-based bank covering school history, campus life and the history and culture of Tai Po district. The frame that makes this wall untransferable. |
| Butterfly life cycle蝴蝶生活史 | Voice AI large model | Real butterfly specimens, with voice Q&A on complete metamorphosis and insect life cycles. |
| Fossil specimens化石標本 | Voice AI large model | Real fossils, with voice Q&A on Earth history and evolution. |
| General science quiz科普 | Science quiz | An open four-option bank the teacher can refresh at any time, used for daily self-study and inter-class speed challenges. |
Hardware common to every frame: anodised aluminium-alloy housing, its own display, microphone and speaker, RGB light border, built-in high-brightness LED. A single wall can carry up to 68+ individual frames, and 20 interactive designs are documented in the standard library (section 07).
05 · Central focus
The 55-inch AI digital human is the school’s own mascot
A 55-inch vertical touchscreen runs the AI digital-human solution. The school supplied its own mascot image, so the avatar stands in a virtual campus built from the school’s own building and the presenter the pupils talk to belongs to their school. Pupils switch the Chinese or English interface on screen and ask by voice; the avatar replies and broadcasts the answer aloud.
- Custom avatar
- Digital-human avatar built from an image supplied by the school: a mascot, a logo character or a real person.
- 2D presenter clone
- One customised and trained 2D real-person presenter; end-to-end optimised chain from speech input to avatar broadcast in no more than 3 seconds.
- Lip-sync training
- Deep-learning, speech-driven mouth movement matched to the broadcast content, closer to natural speech than traditional mouth-shape libraries.
- Voice cloning
- Small sample sets reproduce a target voice; the cloned voice is usable for live interaction and content broadcast.
- Speech recognition
- Built-in enterprise ASR engines for real-time recognition of multiple spoken commands.
- LLM knowledge base
- Can connect a large language model to build a school knowledge-base Q&A system for enquiry and teaching support.
- Voice synthesis
- Built-in TTS engine with no fewer than 40 broadcast voices for multi-language, multi-scenario output.
- Backend management
- Content, knowledge bases and question banks are maintained by the school through the management console.
Specification figures are the solution’s published design targets, not an on-site benchmark of this installation. Language switching covers Mandarin, English and Cantonese; the large-language-model service is configured according to each school’s requirements and network environment.
06 · In use
Break time is the real teaching slot
Because the wall lives in a corridor rather than a booked special room, most interaction happens in forty-second bursts between lessons. That is the design intent: language production needs repetition, and repetition needs a low-stakes moment rather than a timetable.
Ask out loud
A pupil walks up and speaks to a frame in Cantonese, Mandarin or English. No typing, no queue, no teacher required.
Answer in the target language
Speech recognition hands the question to that frame’s knowledge base; the reply is spoken back in Mandarin or English through the frame’s own speaker.
Look at the physical evidence
The object inside the frame — space-station model, butterfly specimens, fossil, type blocks — turns an abstract spoken answer into something a pupil can point at.
Turn it into a contest
The teacher adds questions in the backend and the same frame becomes a four-button quiz: study-practice mode for self-study, speed-challenge mode for class competitions.
Speaking practice without audience risk
Pupils listen and answer repeatedly in a game setting, which lowers the hesitation barrier around speaking Mandarin and English aloud.
Cross-subject coverage
Themes run across language, general studies, science, Chinese culture, geography and space, so different departments can each find a hook in the same wall.
Content the school owns
The avatar, knowledge bases and quiz banks are school-editable, so the wall can be updated as the curriculum changes instead of becoming decoration.
AI literacy by contact
Speech recognition, large language models, speech synthesis and digital humans are experienced directly rather than described on a poster.
Uses beyond the lesson
Lesson extension, free exploration at break, parents’ day and open-day displays, plus school-wide quiz challenges.
What we do not claim
No usage counts, test scores or survey results have been published for this installation. The points above are the project’s stated teaching scope, not measured outcomes.
07 · Module library
Twenty documented frame designs, up to 68+ frames on one wall
The nine frames above were built for this school. The standard library is what a school picks from when it wants a faster specification: large-model Q&A, voice and gesture interaction, and instrument-style science exhibits, all in the same anodised aluminium housing with its own display, microphone, speaker and RGB border.
| Frame | Core interaction | Where schools put it |
|---|---|---|
| Universal AI LLM | Voice Q&A, image recognition, text answers | STEAM room, library, feature wall |
| AI science interactive display | Custom knowledge base, voice Q&A | School history room, library, science room |
| Voice Q&A waste sorting | Voice recognition, AI classification, eco education | STEAM room, corridor feature wall |
| Advanced AI pose detection | Skeleton pose tracking in real time | STEAM room, gym |
| AI robotic hand | Depth-camera hand recognition, motion mirroring | STEAM room, school history room |
| Smart weather station | Voice weather query, multi-sensor live data | Science room, STEAM room |

08 · Delivery model
