With　a　growing　population　of　elderly　people,　more　Web　pages　designed　for　the　elderly　appear.　The　design　of　Web　pages　not　only　is　required　to　meet　the　physical　characteristics　of　the　elderly,　but　also　needs　to　meet　the　characteristics　of　elderly　visual　behaviors.　This　study　aims　to　investigate　the　strategy　of　elderly　people　in　visual　search　and　browse　on　Web　pages　using　eye-tracking.　The　experimental　results　showed　that,　in　visual　search,　the　elderly　people　were　under　a　higher　mental　load,　and　more　likely　to　pay　attention　to　the　peripheral　area;　whereas　in　visual　browse,　their　mental　load　is　lower,　and　more　likely　to　pay　attention　to　central　area.　The　results　indicate　that,　the　Web　pages　designed　for　the　elderly　should　try　to　put　the　title　with　the　hyperlink　feature　on　the　peripheral　area,　and　put　the　main　information　content　on　the　central　area.　Furthermore,　it　should　take　measures　to　reduce　the　mental　stress　of　the　elderly　in　visual　search　on　Web　pages.
