A plurality of magnets are positioned at respective relative locations on one of the album portion or the plurality of pages. A plurality of magnetic field sensor means, such as Hall effect sensors, are positioned at respective relative locations on the other of the album portion or the plurality of pages which substantially match the respective locations of the plurality of magnets for sensing the position of each page relative to the other portion. ## Claims ### Claim 1 An album comprising a plurality of pages and another portion, is characterized by: a plurality of magnets positioned at respective relative locations on one of said portion or said plurality of pages; and a plurality of magnetic field sensor means positioned at respective relative locations on the other of said portion or said plurality of pages which substantially match the respective locations of the plurality of magnets for sensing the position of each page relative to the other portion. ### Claim 2 (depends on 1) The album of claim 1, wherein said other portion includes a front cover of the album. ### Claim 3 (depends on 1) The album of claim 1, wherein said other portion includes a back cover of the album. ### Claim 4 (depends on 1) The album of claim 1, wherein said other portion includes a front and back cover of the album. ### Claim 5 (depends on 1) The album of claim 1, wherein said other portion includes a binder for joining a front and back cover of the album together. ### Claim 6 (depends on 1) The album of claim 1, wherein said magnets are permanent magnets. ### Claim 7 (depends on 1) The album of claim 1, wherein said magnets are positioned on said pages. ### Claim 8 (depends on 1) The album of claim 1, further comprising: means for storing and playing back sound recordings associated with images to be secured to the pages; means for determining, based on an output signal from the magnetic field sensors, which images in the album are being presented to a viewer of the album; and means for causing the storing and playing means to play back a sound recording associated with the presented images. ### Claim 9 An album page for presenting one or more images comprises a base sheet for supporting the images, means for securing images to the base sheet, and means for securing the base sheet to an album, is characterized by: a permanent magnet attached to the base sheet in a predetermined position, such that when the base sheet is secured to an album having a magnetic field sensor, the base sheet can be moved to at least one position where a magnetic field from the permanent magnet can be sensed by the magnetic field sensor and at least one position where the magnetic field from the permanent magnet cannot be sensed by the magnetic field sensor, such that the position of the base sheet in the album relative to the magnetic field sensor can be determined. ### Claim 10 An album, comprising: a plurality of magnetic field sensor means positioned at respective relative locations on a portion of the album such that when a plurality of pages are secured to the album, each page having a permanent magnet positioned at a respective relative location on the page which substantially matches the respective location of one of the magnetic field sensors, the position of each page relative to the portion of the album can be sensed. ### Claim 11 (depends on 10) The album of claim 10, wherein said album portion includes a front cover of the album. ### Claim 12 (depends on 10) The album of claim 10, wherein said album portion includes a back cover of the album. ### Claim 13 (depends on 10) The album of claim 10, wherein said album portion includes a front and back cover of the album. ### Claim 14 (depends on 10) The album of claim 10, wherein said album portion includes a binder for joining a front and back cover of the album together. ### Claim 15 (depends on 10) The album of claim 10, further comprising: means for storing and playing back sound recordings associated with images to be secured on the pages; means for determining, based on an output signal from the magnetic field sensors, which images in the album are being presented to a viewer of the album; and means for causing the storing and playing means to play back a sound recording associated with the presented images.
