The revolution of technology brings many benefits towards diverse population. Digital game is one of the digital technologies that has potential to facilitate older adults' daily routine. However, some of them faces challenges to adopt the usage of digital games in their daily lives, one of which is that most commercial games are not suitable for older people. This paper discusses the investigation into the challenges associated with the older adults' adoption of digital games, their interaction, and experiences with digital games and specifically explores the andragogical perspectives, and game design attributes. A set of questionnaires consisted of open-ended and close-ended questions were distributed, targeting the older adults across Malaysia, using online and non-probability sampling technique. 81 respondents were recruited, and 56 respondents (n=56) were eligible in this study. Four participants were recruited for informal interview session. The analysis of the results indicates that the older adults' perception of digital games and game design aspects are the major factors influencing their digital game adoption. Game designs are important to attract many older adults to experience and interact with digital games.
The use of low power sensor nodes to collect useful sensing information effectively is critical for any wireless sensor network (WSN) application to last longer. To increase network lifetime, energy consumption is considered as one of an essential performance metric. Most of the current proposed routing protocols proposed to reduce the amount of energy consumed and to increase the network lifetime. The common pioneer hierarchical routing protocol for wsn such as Low Energy Adaptive Cluster Hierarchical Routing (LEACH) is also proposed to improve the energy efficiency of WSN. LEACH is a cluster based routing protocol in which sensor nodes are combined together to form separate clusters and every cluster has a leader node named cluster head (CH). In this paper, we have done the analytical study of LEACH protocol to identify to what extent LEACH protocol can perform in terms of average energy consumption and packet loss for different data rate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
