Despite having numerous platforms to promote coronavirus awareness, a part of the population is not well informed about the basic knowledge related to the pandemic. This inspired us to design and implement a free-to-play game, Unlock Me , to help people learn about coronavirus easily yet effectively. A user-centric approach to designing the game has helped us understand the challenges people face and eventually to deliver an interactive game. We conducted an evaluation study across multiple age groups to understand the impact of Unlock Me to enhance COVID-19 learning of the player and to evaluate the quality of the game. The results are obtained by studying the player behavior and performing comparative analysis with Model for the Evaluation of Educational Games (MEEGA+), a standard game evaluation model. Our evaluation shows that there has been an increase in the awareness of players by 53% compared to pre-game awareness. 52.40% of the players found the game to be usable with a good player experience and learning.

The number of dementia patients has been increasing worldwide. With a busy schedule nowadays, family members do not have the time to assist and help a member with dementia in their family. The dementia patients must take care of themselves and improve their cognitive abilities. Hence, a fun and interactive platform needs to be developed. This paper presents the design, development, and evaluation of a gamebased approach to improve cognitive and physical abilities. With the help of User-Centric Design(UCD) and Human computer Interaction(HCI) principles, a usable and interactive game has been developed to help people fight dementia
