Abstract: There is provided an information processing apparatus including a projection control unit (150) that causes visual information to be projected onto a projection surface. The visual information corresponds to content that is provided to the projection surface and disposed on a first object. The content is identified on the basis of a recognition result of the first object and a recognition result of a second object. The second object is provided along with the first object.

Abstract: Provided is a portable electronic apparatus. The portable electronic apparatus includes a casing, an operation portion, and a finger placement portion. The casing includes a front surface and a back surface. The operation portion is disposed at a first position on the front surface and is operated with a first finger of a user for an input. The finger placement portion is disposed at a second position on the back surface. The second position corresponds to the first position. The finger placement portion guides a second finger of the user to be capable of being placed thereon.

Abstract: A telephone device that has a call subscriber telephone number detector, a memory for memorizing a plurality of call subscriber information audio signal in advance and which can memorize an arbitrary call subscriber telephone number in correspondence with a call subscriber information audio signal arbitrarily selected from the plurality of call subscriber information audio signals, a comparator for comparing whether a call subscriber telephone number detected by the call subscriber telephone number detector is coincident with a call subscriber telephone number memorized in the memory, upon coming-call, and an electroacoustic transducer to which a call subscriber information audio signal read out from the memory is supplied, wherein when it is detected by the comparator that a call subscriber telephone number detected by the call subscriber telephone number detector is coincident with a certain call subscriber telephone number memorized in the memory, a certain call subscriber information audio signal corre

Abstract: To enable the simple and satisfactory connection of a plurality of telephone sets, data communication devices and similar to a single telephone line. A telephone set comprises a telephone circuitry portion, connected to a telephone line via switching means; an external equipment terminal, connected to the telephone line via switching means; line capture detection means which detects capture of the telephone line by a device connected to the external equipment terminal; and control means, which causes the first switching means, to be disconnected while the line capture detection means detects line capture, causes the second switching means, to be disconnected while telephone line capture by the telephone circuitry portion is detected, and causes the switching means to all be in the connected state when neither line capture is detected.

Abstract: An automatically answerable telephone apparatus comprises a control unit having a rewritable memory for storing control data for automatically responding operation and operative to control a line signal processor and a recording and reproducing device, a writable non-volatile memory, a power source for supply a power supply voltage, a capacitor connected for holding the power supply voltage, and a power failure detector, wherein the control unit is operative, with the power supply voltage discharged by the capacitor to remove operating portion other than the control unit and the writable non-volatile memory from the power source and to transfer the control data for automatically responding operation from the rewritable memory to the writable non-volatile memory for preserving the control data when power failure occuring in the power source is detected by the power failure detector.
