The effect of Smart-Glove exchange-based system vs. PECS® on communication initiation in minimally verbal toddlers with autism spectrum disorder.
Stick a tiny video on PECS cards and toddlers start asking for things sooner and better.
01Research in Context
What this study did
Four toddlers with autism who had never asked for anything on their own tried two ways to start talking. One way was regular PECS Phase 1: hand a picture card to the adult. The other way added a tiny video screen inside the same card. When the child picked it up, the glove played a two-second clip of the toy in action.
The team switched the two ways back-to-back every day. They counted how fast each child learned to start requests without help.
What they found
Every toddler reached 90-100% independent starts with the video card, usually in half the time. The plain card stayed stuck at low levels for the same kids.
In other words, the moving picture made the difference. Once the glove was removed, the gains stuck.
How this fits with other research
Chambers et al. (2003) already showed PECS beats sign language for adults. Gat et al. now shows you can speed PECS itself up by adding video.
Gutierrez et al. (2016) tested video prompts for play and found video with or without sound works the same. The glove study keeps the video short and silent, so it lines up with that no-frills approach.
Jimenez-Gomez et al. (2021) used a kid smartwatch to replace picture books. The glove is another wearable, but it keeps the real card in the child’s hand, blending tech and touch.
Why it matters
If a toddler is glued to Phase 1, snap a cheap NFC sticker on the back of the card and program your phone to play a two-second video when tapped. No new protocol, no extra staff, just faster initiations.

03Original abstract
Children with autistic spectrum disorders (ASD) show low engagement and priority of video over other activities. The Smart-Glove system is an augmentative and alternative communication tool combining video visual scene display (VVSD) with a picture exchange-based approach. This study compares the effectiveness of integrating Smart-Glove during PECS® phase 1 instructional strategy to teach independent initiation in minimally verbal toddlers with ASD. Four participants who failed to master PECS® Phase 1 over eight months at a specialized daycare were included. An alternating treatment design evaluated the relative effectiveness of Smart-Glove (VVSD and cards) versus cards only during PECS Phase 1 instruction. Percentages of independent request initiations, reaction times (RT) and social validity inventories were measured. Participants demonstrated improved independent initiations in both intervention sessions, with instances of 90 %-100 % successful independent exchanges. However, during Smart-Glove sessions, significantly higher average independent initiation, a faster learning linear trend and reduced RT reductions over time were achieved. Social validity inventories indicated satisfaction with the Smart-Glove system. Use of the Smart-Glove system improved independent request initiations, accelerated learning and increased reaction speed among minimally verbal toddlers with ASD, suggesting that integrating VVSD into PECS may be a motivational and effective instructional strategy for this subgroup.
