  • Patent number: 10838581
    Abstract: Electronic equipment is controlled with a touching-type signal input device. An inputted navigator-calling request that specifies a user request to navigate among a set of previously-opened application views of different applications is received. A request mode of the inputted navigator-calling request is compared with a predefined request mode associated with navigation among the set of previously-opened application views of the different applications. It is determined whether the request mode of the inputted navigator-calling request matches with the predefined request mode. An open-views navigator is displayed in response to determining there is a match. The open-views navigator has a set of open-views tabs distributed on at least part of a closed structure that each allow selective navigation to a previously-opened application view of one of the different applications.
