In　the　process　of　modernization,　the　rights　and　needs　of　children　in　community　public　spaces　have　increasingly　become　a　focal　point　of　societal　attention.　The　design　of　children’s　public　spaces　reflects　the　overall　fairness　and　harmony　of　the　community.　However,　with　the　rapid　development　of　cities,　the　distribution　of　spatial　resources　may　exhibit　inequities,　directly　affecting　the　quality　of　life　for　different　social　groups.　Therefore,　it　is　necessary　to　conduct　in-depth　research　on　the　design　of　community　children’s　public　spaces　from　the　perspective　of　fairness,　integrating　the　TAM　model　to　explore　the　interaction　design　issues　of　public　spaces.　This　will　help　to　reasonably　enhance　the　quality　of　spatial　provision,　optimize　residents’　living　environments,　and　promote　the　realization　of　social　equity.　This　study　focuses　on　community　children’s　public　spaces　in　Xiamen,　Fujian　Province,　aiming　to　transform　traditional　communities　into　child-friendly　environments.　Based　on　the　principle　of　fairness,　three　dimensions　are　proposed　for　spatial　design:　social　fairness,　resource　fairness,　and　opportunity　fairness.　The　TAM　model　is　used　to　identify　the　key　attributes　that　drive　users’　satisfaction　with　the　community　environment,　thereby　constructing　a　model　for　the　usage　intentions　of　community　children’s　public　spaces.　Through　surveys　and　interviews,　specific　opinions　and　suggestions　from　residents　regarding　space　usage　are　collected,　providing　foundational　data　for　improving　interaction　design.　The　study　focuses　on　human-computer　interaction　elements,　exploring　how　interaction　design　can　enhance　user　experience.　Based　on　a　systematic　analysis　of　public　space　satisfaction　evaluation　results,　scientific　design　strategies　are　proposed.　The　aim　of　this　study　is　to　chart　a　path　for　the　future　development　of　child-friendly　communities,　providing　scientific　support　for　the　planning　and　management　of　children’s　public　spaces,　and　offering　data-driven　directions　for　their　evolution　and　improvement.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG　2025.
