# A Hand Motor Skills Rehabilitation for the Injured Implemented on a Social Robot
## 4 Evaluation
### Qualitative Evaluation  
As mentioned before, surveys were handed to the hosts of the experiments in order to qualitatively evaluate HaReS as a whole system. The survey covered a range of different aspects, from the usability to the impact in the rehabilitation. The results are shown in Table 1. The score was averaged among the answers of both organizations and were in the range of 1-5, 1 being totally disagree and 5 being fully agree.  
\begin{table}
\begin{tabular}{c c} \hline \hline
**ID** & **Question** & **Score** \\ \hline
1 & The exercises implemented in HaReS overall helped to improve the motor skills of the patients & 4 \\ \hline
2 & The exercises implemented in HaReS helped to improve the adherence at home to the rehabilitation plan & 5 \\ \hline
3 & The exercises implemented in HaReS effectively cover a common rehabilitation plan & 3 \\ \hline
4 & The hand poses provided by the Leap Motion controller are accurate enough & 4.5 \\ \hline
5 & The HaReS interface is comprehensive and easy to use & 4 \\ \hline
6 & HaReS is a motivating factor for the therapists & 5 \\ \hline
7 & HaReS is a motivating factor for the patients & 5 \\ \hline
8 & The use of a social robot is critical in terms of motivation for the therapists & 2 \\ \hline
9 & The use of a social robot is critical in terms of motivation for the patients & 4 \\ \hline
10 & HaReS helped the therapists to provide a better service & 4 \\ \hline
11 & HaReS helped the therapists to provide service to more patients & 3 \\ \hline \hline \end{tabular}

Table 1: Questions and corresponding scores of the survey conducted in two different facilities for motor and cognitive rehabilitation.  
Regarding the results of the survey, the therapists and patients agreed that HaReS helped to improve the motivation of the two groups. Therapists remarked that HaReS indeed helped to improve the motor skills of the patients at the same level of the traditional rehabilitation methodology, and also stated that the proposal helped to provide services to more patients at the same time. For the patients, the use of a social robot was a motivation factor that improved the user experience and engagement. Nonetheless, the therapists stated that the robot had no effect in their motivation, nor on the results of the rehabilitation plan. Regarding the accuracy of the hand poses, the therapists stated that it was acceptable, and that it seldom lost track of the hands or depicted incorrect poses.  
In addition to the survey, the therapists also offered valuable feedback. The comments included that HaReS could benefit from more exercises. They also suggested to somehow involve gamification to further improve the adherence to the rehabilitation plan and to enhance the appeal of HaReS. Finally, they proposed the use of a virtual reality setup that provides a better immersion of the patients in order to further improve their experience and the efficiency of the functional exercises.  
As a conclusion, we can mention that HaReS indeed helped in the motivation of both therapists and patients, and that HaReS helped to optimize the time that the therapists used to provide services to more patients at the same time.
