The image transfer structure is configured to relay or transfer, above the touch-sensitive display, an optical display plane of an image displayed by the touch-sensitive display. Further, the capacitive marker is capacitively-recognizable by the touch-sensitive display such that the touch-sensitive display visually presents the image in alignment with the image transfer structure. ## Claims ### Claim 1 An accessory configured to be placed on a display surface of a touch-sensitive display, the accessory comprising: a base movable relative to the display surface; an image transfer structure configured to relay or transfer, above the display surface, an optical display plane of an image displayed by the touch-sensitive display; a gripping member moveable relative to the base, the gripping member forming an aperture at least partially filled by the image transfer structure; a logic device configured to derive user input information from a relative position of the gripping member and the base; and a communication interface configured to send the user input information to the touch-sensitive display. ### Claim 2 (depends on 1) The accessory of claim 1, wherein the gripping member is configured to rotate relative to the base, and wherein the logic device is configured to derive the user input information from a relative rotational position of the gripping member and the base. ### Claim 3 (depends on 1) The accessory of claim 1, wherein the gripping member is configured to translate relative to the base, and wherein the logic device is configured to derive the user input information from a relative translational position of the gripping member and the base. ### Claim 4 (depends on 1) The accessory of claim 1, wherein the gripping member is configured to rotate and translate relative to the base, and wherein the logic device is configured to derive the user input information from a relative translational position of the gripping member and the base and a relative rotational position of the gripping member and the base. ### Claim 5 (depends on 1) The accessory of claim 1, wherein the image transfer structure includes a view surface and an interface surface spaced apart from the view surface, wherein the interface surface is configured to be placed on the touch-sensitive display, and wherein the image transfer structure is configured to relay or transfer the display plane of the image to the view surface. ### Claim 6 (depends on 5) The accessory of claim 5, wherein the image transfer structure includes a fiber optic. ### Claim 7 (depends on 1) The accessory of claim 1, wherein the image transfer structure includes a projection surface and an interface surface spaced apart from the projection surface, wherein the interface surface is configured to be placed on the touch-sensitive display, and wherein the image transfer structure is configured to relay or transfer the display plane above the projection surface. ### Claim 8 (depends on 7) The accessory of claim 7, wherein the image transfer structure includes an array-based imaging sheet. ### Claim 9 (depends on 1) The accessory of claim 1, further comprising: a capacitive marker fixed relative to the base and capacitively-recognizable by the touch-sensitive display. ### Claim 10 (depends on 9) The accessory of claim 9, wherein the capacitive marker includes one or more features from which a rotational orientation of the accessory is recognizable by the touch-sensitive display. ### Claim 11 (depends on 1) The accessory of claim 1, further comprising: a capacitive touch indicator configured such that touch input on the capacitive touch indicator is capacitively-recognizable by the touch-sensitive display. ### Claim 12 An accessory configured to be placed on a display surface of a touch-sensitive display, the accessory comprising: a base movable relative to the display surface; a gripping member moveable relative to the base; and a capacitive marker fixed relative to the base and capacitively-recognizable by the touch-sensitive display; and wherein the accessory is configured to communicate, to the touch-sensitive display, user input information derived from a relative position of the gripping member and the base. ### Claim 13 (depends on 12) The accessory of claim 12, further comprising: a logic device configured to derive the user input information from the relative position of the gripping member and the base; and a communication interface configured to send the user input information to the touch-sensitive display. ### Claim 14 (depends on 13) The accessory of claim 13, wherein the gripping member is configured to rotate relative to the base, and wherein the logic device is configured to derive the user input information from a relative rotational position of the gripping member and the base. ### Claim 15 (depends on 13) The accessory of claim 13, wherein the gripping member is configured to translate relative to the base, and wherein the logic device is configured to derive the user input information from a relative translational position of the gripping member and the base. ### Claim 16 (depends on 13) The accessory of claim 13, wherein the gripping member is configured to rotate and translate relative to the base, and wherein the logic device is configured to derive the user input information from a relative translational position of the gripping member and the base and a relative rotational position of the gripping member and the base. ### Claim 17 (depends on 12) The accessory of claim 12, wherein the capacitive marker includes one or more features from which a rotational orientation of the accessory is recognizable by the touch-sensitive display. ### Claim 18 (depends on 12) The accessory of claim 12, further comprising: an image transfer structure configured to relay or transfer, above the touch-sensitive display, an optical display plane of an image displayed by the touch-sensitive display. ### Claim 19 An accessory configured to be placed on a display surface of a touch-sensitive display, the accessory comprising: a base movable relative to the display surface; a gripping member moveable relative to the base; a logic device configured to derive user input information from a relative position of the gripping member and the base; and a communication interface configured to send the user input information to the touch-sensitive display. ### Claim 20 (depends on 19) The accessory of claim 19, further comprising: an image transfer structure configured to relay or transfer, above the display surface, an optical display plane of an image displayed by the touch-sensitive display; and wherein the gripping member forms an aperture at least partially filled by the image transfer structure.
