  • Patent number: 7103571
    Abstract: Even goods of a low price can be handled at a virtual shop and services to the user side are improved. When a payment instruction of certain goods is issued from a user's terminal 1, a paying method presenting unit (21) of a virtual shop (2) presents a paying method using a prepaid type electronic money by the sale on a network (6). When the payment instruction by the prepaid type electronic money is issued from the user's terminal, an electronic money purchasing unit (22) purchases the prepaid type electronic money by using a settlement unit on the network, subtracts a payment money amount of the goods from a money amount of the purchased prepaid type electronic money, and notifies the user's terminal of a balance.

  • Patent number: 7031940
    Abstract: A system which improves convenience on the user side and contributes to a cost reduction on the sales shop side is provided. A sales shop 2 manages requested contents to the users by a notice information management unit (22) in correspondence to a URL provided for each user. A requested contents notice unit (23) notifies the user of the requested contents managed by the notice information management unit (22) and the user's URL by Email. When there is an access to the URL in the Email from the user and a paying instruction is issued with respect to the requested contents, a settlement unit (24) makes a settlement on a network (5).

  • Publication number: 20060004724
    Abstract: An information-processing system includes a phrase category processing unit, a first hypertext document generating unit, a first correlation management unit, a second correlation management unit that manages a correlation between one or a plurality of action categories and the locations of application function units and a selection accepting unit. As a user specifies a phrase in a first hypertext document, the first correlation management unit is engaged to search for an action category corresponding to the phrase category of the phrase. As the user selects an action by using a dialogue component in a second hypertext document provided by the selection accepting unit, the application function unit corresponding to the action category of the action is started up by engaging the second correlation management unit to search for the location of the application function unit.

  • Patent number: 6359602
    Abstract: In a head-mounted display device, image display light emitted from a display device is directed towards the eye of an observer by changing the light path thereof by means of an optical system. The display device, optical system and a drive signal generating device for the display device are worn on the head of the observer by means of a holding member. This optical system is positioned in front of the display device emitting display light in a forward direction from a position separated radially from the visual axis of the observer when looking straight ahead. The drive signal generating device is located in a position separated radially from the visual axis with an interval from the display device and optical system.
