Augmented　Reality　(AR)　technology　provides　many　opportunities　to　enhance　people＇s　experience　in　interacting　with　data.　Midair　gesture,　a　natural　interaction　mode　in　AR,　interacts　with　virtual　elements　without　any　auxiliary　devices.　It　has　become　a　hot　topic　of　interest　for　researchers　with　the　development　of　gesture　recognition　technology.　From　the　perspective　of　user　experience,　the　types　of　midair　gesture,　gesture　recognition　technology,　applications　were　discussed.　The　challenges　of　air　gesture　interaction　from　two　aspects　of　user　experience　and　technology　were　analyzed,　and　the　importance　of　collaborative　gesture　and　low-cost　user　experience　in　the　future　were　emphasized.　Finally,　the　application　prospect　of　air　gesture　interaction　distance　education,　medical　health,　industry,　office,　and　so　on　is　discussed.
