recent years boom different natural interaction paradigms touch tangible gesturebased interfaces make better use humans innate skills rather imposing new learning processes however work reported systematically evaluates interfaces influence users performance regard level digital literacy even age furthermore also important understand interaction paradigms impact performing basic operations data selection insertion manipulation interface could efficient task paper reports first step exploratory evaluation relationship different interaction paradigms specific targetaudiences dealing selection task conducted experiment 60 subjects evaluate different interfaces may influence performance specific groups users four input modalities evaluated selection task results different user groups reported terms performance efficacy error rate user preference group users determined statistically significant difference mean time taken complete task interface also one input modality every user accustomed computer mouse one showed discrepancy regarding performance groups believe study raises new issues future research
