A detachable spectacles-mounted augmented reality (AR) device and clip-on unit wherein the device has a housing (31) configured for detachably supporting the clip-on unit, an exit window (30) and an entrance window (30′) in the housing through which the user observes a scene, a communications interface (71, 74) for coupling to a hand-held device, and a camera (37) inside the housing for imaging the scene observed by the user through a camera window (36) and configured to convey an image of the scene to the hand-held device. A line-of-sight guide unit (39) displays at least one marker at the user's field of view for directing a line of sight of the user toward a designated feature in the scene, and optics (40) within the housing projects the marker at a distance for superimposing on to the scene viewed by the user.
An optical accessory (10) attachable to a computing device (13) having a display screen (12) has a housing (24) configured for mechanically attaching to the display screen of the computing device regardless of geometry of the device while impeding mutual displacement of the accessory relative to the device after attachment. Viewing optics (14) images content displayed by the computing device within a portion (18) of the display screen operative to convey content to the optical accessory. Means (25) are operative after the accessory is attached to the computing device for identifying one or more points of the display screen and to which stored program code in the computing device is responsive for determining an active portion in which content is displayed whereby the content is displayed within an imaging field of view of the accessory without requiring that the accessory be attached in predetermined registration to the device.

Accessories and methods are disclosed for projecting content generated by a hand-held device (100) on reality. An accessory (2) includes a housing (102) configured for mechanically attaching to the hand-held device, and viewing optics (108) within the housing configured to project an image of content generated by the hand-held device on reality via a see through display (23). In some applications, the hand-held device is a smartphone.

An apparatus (15) for counting air particles includes a casing (22) and an illuminator (28, 29) inside the casing that substantially uniformly illuminates a slice (26) of air inside a volume of the casing located within a depth of focus of a camera, which simultaneously images particles (27) within the slice, allowing the image to be subsequently analyzed to count the number of particles. The apparatus may fit on to an external device such as a smartphone that includes the camera and whose flash may serve as a light source for the illuminator.
