Abstract
Games possess “the power to stimulate intellectual curiosity” and “the power to captivate people”, making them
crucial elements to consider in serious game development. On the other hand, applying this power could enhance the appeal
of everyday apps. Therefore, aiming to elucidate methods for applying these capabilities to such apps, we prototyped LHS
3.0 using a Life History Support System currently under development by our team and accumulated trial experience from
over 200 users. This paper reports findings from fieldwork conducted within a community of families sharing common goals
and values. Over approximately one year, 42 individuals recorded and viewed 433 topics using LHS 3.0. The findings are
systematized and presented to inform the development of the next version.
