"It Is Not the Robot Who Learns, It Is Me." Treating Severe Dysgraphia Using Child-Robot Interaction.

Area of Science:

• Human-Computer Interaction
• Developmental Psychology
• Assistive Technology

Background:

• Writing disorders, particularly severe dysgraphia, significantly impair children's academic and daily functioning.
• Traditional interventions for dysgraphia have limited success, highlighting the need for innovative therapeutic approaches.
• Social robots offer potential for engaging and personalized interventions to enhance motivation and skill acquisition in children.

Purpose of the Study:

• To investigate the feasibility and efficacy of a child-robot interaction scenario (Co-writer) for improving severe dysgraphia.
• To assess the impact of robot-assisted writing therapy on a child's motivation, behavior, and handwriting quality.
• To explore the potential of tailored games within the Co-writer system to train specific writing controls (pressure, tilt, speed, letter liaison).

Main Methods:

• A 10-year-old boy with severe dysgraphia and complex neurodevelopmental disorders participated in the Co-writer scenario.
• The intervention involved the child teaching a social robot to write via tablet demonstration, complemented by specific training games.
• The setup was implemented over 20 consecutive weekly occupational therapy sessions.

Main Results:

• Significant improvements were observed in the child's motivation, with a disappearance of avoidance behaviors during therapy and at school.
• Marked enhancements in handwriting quality and postural control were documented.
• The child's participation in classroom activities improved due to better writing abilities.

Conclusions:

• Child-robot interaction, specifically the Co-writer scenario, is a feasible and effective method for treating severe dysgraphia.
• This approach can restore motivation, reduce avoidance, and dramatically improve handwriting and posture in children with writing impairments.
• Further clinical studies are warranted to validate these findings and confirm the broader benefits for children with dysgraphia.
