This study discovered a phenomenon of choice overload in smartphone home screen and intended to shield users appropriately from underlying system complexity. We successively pro-posed two prototypes with effects of “prior disclosure icons” and “second priority disclosure icons”. Both prototypes highlight visual features of the prior disclosure icons by delaying disclosure of others. Research results: (1) Interface of progressive disclosure options effectively highlight the prior disclosure icons of recommendation options and significantly improve choice overload of searching home screen. Prior disclosure icons of high legibility rate on home screen is preferably 3. (2) The application of “second priority disclosure icons” increases high legibility rate icons, and the highly legible prior disclosure icons in 2000 ms time frame is 4 (present by 3 + 1) among older users.
