An apparatus and a method for providing a tactile sensation for a virtual image are disclosed. The disclosed apparatus includes: a display unit for displaying an image including a virtual image; an image acquisition unit for acquiring an image of a user body; a determiner unit for determining whether or not a user attempts an interaction with the virtual image by using an image acquired by the image acquisition unit; a content analyzer unit for acquiring a time at which a virtual image is shown and position information of the shown virtual image from a displayed content; a tactile-sensation provider unit for providing a tactile sensation to a preset body part of the user based on a determination result of the determiner unit; and a tactile-sensation provision controller for adjusting an ejector nozzle of the tactile-sensation provider unit based on a virtual image showing time and position acquired by the content analyzer unit. The disclosed apparatus can enable the user to interact with a virtual image with verisimilitude.

A method for wireless communication, and more particularly, a method for reducing the number of temporal connections in Bluetooth devices when obtaining neighboring Bluetooth device names is provided. The method for reducing temporal connections in Bluetooth devices comprises determining whether other Bluetooth devices are present, obtaining a name by temporally connecting to a Bluetooth device whose presence has been determined and determining whether other Bluetooth devices are present after a predetermined time has passed, and then obtaining a changed name through a temporal connection only to other Bluetooth device whose name has been changed. According to the above method, blocking temporal connections to Bluetooth devices whose name has not changed according to changes in the UNDEF field of FHS packets enables a reduction in the frequency of temporal connections.
