- The use of game modes to promote engagement and social involvement in multi-user serious games: a within-person randomized trial with stroke survivorsPublication . Pereira, Fábio; Bermúdez i Badia, Sergi; Jorge, Carolina; Cameirão, Mónica S.Serious games are promising for stroke rehabilitation, with studies showing a positive impact on reducing motor and cognitive defcits. However, most of the evidence is in the context of single-user rehabilitation, and little is known concerning the impact in multi-user settings. This study evaluates the impact that diferent game modes can have on engagement and social involvement during a two-user game. Specifcally, we want to under stand the benefts of game modalities based on competition, co-activation, and collaboration and analyze the infu ence of diferent motor and cognitive defcits and personality traits. Methods: We developed a two-player setup—using tangible objects and a large screen interactive table—for upper limb rehabilitation purposes. We implemented a game that, while keeping the same basic mechanics, can be played in the three diferent modes (Competitive, Co-active, and Collaborative). We ran a within-person randomized study with 21 stroke survivors that were paired and played the game in its three versions. We used the Game Experi ence Questionnaire—Core Module to assess engagement and the Social Presence Module to assess Social Involve ment. For personality, motor, and cognitive function, users answered the International Personality Item Pool (short version), Fugl-Meyer Assessment—Upper Extremity, Modifed Ashworth Scale, and Montreal Cognitive Assessment, respectively. Results: The Collaborative mode promoted signifcantly more Behavioral Involvement. The Competitive mode pro moted more Flow and Challenge than the Co-active mode with participants with better cognitive performance, with low extraversion, or with higher motor skills. Participants with higher cognitive defcits reported more Competence with the Co-active mode. Conclusions: Our results indicate that, for multi-user motor rehabilitation settings, the collaborative mode is the more appropriate gaming approach to promote social involvement, showing a high potential for increasing adher ence and efectiveness of therapy. Additionally, we show that a player’s motor and cognitive ability and personality should be considered when designing personalized tasks for multiplayer settings.
- Impact of game mode in multi-user serious games for upper limb rehabilitation: a within-person randomized trial on engagement and social involvementPublication . Pereira, Fábio; Bermúdez i Badia, Sergi; Ornelas, Rúben; Cameirão, Mónica S.Background: Serious games have been increasingly used for motor rehabilitation. However, it is not well known how different game features can be used to impact specific skills properly. Here, we study how the mode (competitive, co-active, collaborative) in which a multi-user game is presented impacts engagement and social involvement. Methods: We collected data from 20 pairs of community-dwelling older adults (71.5 ± 8.7 years) in a study following a within-persons design. The participants performed a two-player upper limb rehabilitation game with three conditions (Competitive, Co-active, and Collaborative modes). Engagement and social involvement were assessed through the Core Module and Social Presence Module, respectively, from the Game Experience Questionnaire. To infer the impact of personality and cognitive function, users answered the International Personality Item Pool (short version) and the Montreal Cognitive Assessment, respectively. Results: Results show that the Collaborative game mode promotes more social involvement when compared to Competitive and Co-active modes. This result is mostly explained by those participants with higher cognitive skills, and those that are more extrovert. Extrovert participants feel more empathy and are behaviorally more involved when playing the Collaborative mode. Also, the Collaborative mode is shown to be appropriate to promote interaction with participants that previously had a distant relationship, while the Competitive mode seems to be more beneficial to promote empathy between players with a closer relationship. Conclusions: The Collaborative game mode elicited significantly higher social involvement in terms of Empathy, Positive Affect, and Behavioral Involvement. Hence, this game mode seems to be the most adequate choice to be used in multiplayer rehabilitation settings, where social interaction is intended.
