A science museum installed an interactive（交互式的）/ɪntər'æktɪv/ anatomy（解剖）/ə'nætəmɪ/ wall for a public health week. Visitors touched a bodily（整体地）/'bɒdɪlɪ/ region, completed a movement, and received a printed explanation. By opening day, however, the wall was issuing personal diagnoses from educational labels. Medical educator Rina Park stopped the printer and asked technicians to carry out（实施）/ˈkæri aʊt/ a review of the program in question（所涉及的）/ɪn ˈkwestʃən/. The team read each rule in light of（鉴于）/ɪn laɪt əv/ its source. No visitor result could leave the gallery until every rule had a defensible source.

The central diagram mixed anatomy with physiology（生理学）/,fɪzɪ'ɒlədʒɪ/. It correctly located the larynx（[解剖] 喉）/'lærɪŋks/, thyroid（甲状腺）/'θaɪrɒɪd/, spleen（脾脏）/spliːn/, bladder（膀胱）/'blædə/, intestine（内部的）/ɪn'testɪn/, navel（[解剖] 肚脐）/'neɪv(ə)l/, anus（[解剖] 肛门）/'eɪnəs/, and surrounding anal（[解剖] 肛门的）/'eɪn(ə)l/ region. Other layers showed a capillary（毛细管）/kə'pɪlərɪ/, tendon（[解剖] 腱）/'tendən/, ligament（韧带）/'lɪgəm(ə)nt/, cellular（细胞的）/'seljʊlə/ tissue, a chromosome（[遗][细胞][染料] 染色体（形容词chromosomal）/'krəʊməsəʊm/, an ovum（[细胞][组织] 卵）/'əʊvəm/, and hormone（[生理] 激素）/'hɔːməʊn/ signalling. A private adult module described prostate（前列腺的）/'prɒsteɪt/ conditions and impotence（[泌尿][中医] 阳萎）/'ɪmpətəns/ without attaching either to a person. The software nevertheless converted every opened label into a finding. Reading about a structure became evidence that the visitor had a disorder there.

Eye, skin, and dental panels required separate logic. Cornea（[解剖] 角膜）/'kɔːnɪə/, iris（[解剖] 虹膜）/'aɪrɪs/, and retina（[解剖] 视网膜）/'retɪnə/ were structures; cataract（[眼科] 白内障）/'kætərækt/ was a condition. A visitor might squint（眯眼看）/skwɪnt/ because the screen was glaring（耀眼的）/'gleərɪŋ/, not because an eye disease had been detected. The scalp（头皮）/skælp/ display distinguished scurf（头皮屑）/skɜːf/ from eczema（[皮肤] 湿疹）/'eksɪmə; 'ekzɪmə/. Fingernail（手指甲）/'fɪŋgəneɪl/ and toenail photographs included a minor hangnail（手指头的倒拉刺（指甲旁的逆刺皮））/'hæŋneɪl/, while dentistry（牙科学）/'dentɪstrɪ/ materials explained oral care. None of these images replaced examination. The panels offered no basis for（没有……的依据）/nəʊ ˈbeɪsɪs fɔː/ turning visual resemblance into diagnosis.

Movement stations created a second source of false alarms. One task asked visitors to extend a forearm（前臂）/'fɔːrɑːm/ and point with a forefinger（食指）/'fɔːfɪŋgə/; another tested a hamstring（腿筋）/'hæmstrɪŋ/, instep（脚背）/'ɪnstep/, and the nape（颈背）/neɪp/ of the neck. A headset（耳机）/'hedset/ delivered instructions, and an earplug（耳栓）/'ɪəplʌg/ reduced distracting noise. When a child began to goggle（眼珠转动）/'gɒg(ə)l/ at an animation or shifted posture, the camera marked abnormal movement. A surgical（外科的）/'sɜːdʒɪk(ə)l/ tray picture containing a scalpel（解剖刀）/'skælp(ə)l/ and forceps（[医] 钳子）/'fɔːseps; -sɪps/ also triggered a treatment code, although it was merely illustrating instruments. Percussion（[临床] 叩诊）/pə'kʌʃ(ə)n/ appeared as a clinical examination method, not an instruction to strike a visitor.

The risk library was even broader. Cards on cholera（[内科] 霍乱）/'kɒlərə/, influenza（[内科] 流行性感冒（简写flu））/ɪnflʊ'enzə/, malaria（[内科] 疟疾）/mə'leərɪə/, and measles（[内科] 麻疹）/'miːz(ə)lz/ taught transmission and prevention. Separate guidance contrasted heatstroke（[中医] 中暑）/'hiːtstrəʊk/ with sunstroke（中暑）/'sʌnstrəʊk/ and explained when a stricken（患病的）/'strɪk(ə)n/ person needed urgent care. Migraine（[内科] 偏头痛）/'miːgreɪn; 'maɪ-/, a sniffle（抽鼻涕）/'snɪf(ə)l/, and the tendency to snivel（流鼻涕）/'snɪv(ə)l/ were not interchangeable symptoms. A historical panel described a homeopath（同种疗法医师）/'həʊmɪəpæθ; 'hɒm-/ without endorsing the treatment. Another explained hereditary（遗传的）/hɪ'redɪt(ə)rɪ/ risk and heredity（遗传）/hɪ'redɪtɪ/ but did not predict disease by age（按年龄）/baɪ eɪdʒ/. The printer had combined every card viewed during one session as if curiosity were a medical history. Rina told the museum director, “An exhibit may help someone account for（解释）/əˈkaʊnt fɔː/ a symptom, but it cannot manufacture a patient from the pages they read.”

On that basis（据此）/ɒn ðæt ˈbeɪsɪs/, the museum removed diagnosis language and rebuilt the wall in accordance with（按照）/ɪn əˈkɔːdəns wɪð/ an educational purpose. At this stage（现阶段）/æt ðɪs steɪdʒ/, structure labels opened definitions, movement tasks returned only completion feedback, and disease cards linked to verified care guidance. The system no longer（不再）/nəʊ ˈlɒŋɡə/ stored a visitor’s route. Rina also replaced a cartoon animal snout（鼻子）/snaʊt/ with a labelled human nostril（鼻孔）/'nɒstr(ə)l/ so children would not confuse analogy with anatomy. The revised exhibit encouraged questions while directing actual health concerns to qualified clinicians.
