Research has maintained that playing games via internet or video games can be utilized as a major leisure activity among the elderly and help improve their certain cognitive functions such as memory, concentration, a sense of vitality, etc. Korea is one of the rapidly aging societies, and a serious game for the elderly named 멠aldokangsan2?has been developed in Korea in 2012 as the next version of 멠aldokangsan 1?which was a walking game for two people using controllers of armrests and footboards with PC. As for 'Paldokangsan 2', walking while remembering/choosing healthy food was implemented as game activities in the same game prototype of 멠aldokangsan 1?
