Cellulo is a tangible robot system capable of providing haptic feedback.

It has two primary application domains:

Assistance and rehabilitation

Upper arm rehabilitation for stroke patients (Ozgur et al., 2022). We invesitagted the effect of gamification (Guneysu Ozgur et al., 2020) (Guneysu Ozgur et al., 2020)
Collaborative task assistance for the visually impaired, including a gaming environment (Chibaudel et al., 2020) , and educational activities like teaching shapes and letters (Neto et al., 2020)

Education

Assessing learner behavior via eye-tracking analysis (Olsen et al., 2022)
Understanding how students collaborate while learning mathematical concepts(Khodr et al., 2020) (Johal et al., 2020)
Exploring orchestration of tangible interfaces (Johal et al., 2010)

Task-specific training constitutes a core element for evidence-based rehabilitation strategies targeted at improving upper extremity activity after stroke. Its combination with additional treatment strategies and neurotechnology-based solutions could further improve patients’ outcomes. Here, we studied the effect of gamified robot-assisted upper limb motor training on motor performance, skill learning, and transfer with respect to a non-gamified control condition with a group of chronic stroke survivors. The results suggest that a gamified training strategy results in more controlled motor performance during the training phase, which is characterized by a higher accuracy (lower deviance), higher smoothness (lower jerk), but slower speed. The responder analyses indicated that mildly impaired patients benefited most from the gamification approach. In conclusion, gamified robot-assisted motor training, which is personalized to the individual capabilities of a patient, constitutes a promising investigational strategy for further improving motor performance after a stroke.

Tangible User Interfaces (TUI) have been found to be relevant tools for collaborative learning by providing a shared workspace and enhancing joint visual attention. Researchers have explored the use of TUIs in a variety of curricular activities and found them particularly interesting for spatial exploration. However, very few studies have explored how TUIs could be used as a collaborative medium for people with visual impairments (VIs). In this study, we investigated the effect of tangible interaction (a small tangible robot) in a spatial collaborative task (a treasure hunt) involving two people with VIs. The aim was to evaluate the impact of the design of the TUI on the collaboration and the strategies used to perform the task. The experiment involved six dyads of people with VIs. The results showed that the collaboration was impacted by the interaction design and open interesting perspectives on the design of collaborative games for people with VIs.
