Benefits of technology

[0004]Technology is described to provide a wearable food nutrition feedback system. The feedback system includes a see-through, near-eye, head mounted display having a plurality of sensors detecting information in a field of view of the apparatus. Food items are detected in the field of view and various types of feedback are provided to the wearer of the device. Feedback can include warnings based on personal wearer needs, general nutrition information, food consumption tracking and social interactions. The system includes one or more processing devices in communication with display and the sensors

embodiment 300

[0050]In general, FIG. 3A shows is a flowchart of a method embodiment 300 for aligning a see-through, near-eye, display with an IPD. In step 301, one or more processors of the control circuitry 136, automatically determines whether a see-through, near-eye, display device is aligned with an IPD of a wearer in accordance with an alignment criteria. If not, in step 302, the one or more processors cause adjustment of the display device by at least one display adjustment mechanism for bringing the device into alignment with the wearer IPD. If it is determined the see-through, near-eye, display device is in alignment with a wearer IPD, optionally, in step 303 an IPD data set is stored for the wearer. In some embodiments, a display device 2 may automatically determine whether there is IPD alignment every time anyone puts on the display device 2. However, as IPD data is generally fixed for adults, due to the confines of the human skull, an IPD data set may be determined typically once and s...

third embodiment

[0081]FIG. 5C is a top view of a movable display optical system of a see-through, near-eye, device including an arrangement of gaze detection elements. The display optical system 14 has a similar arrangement of gaze detection elements including IR illuminators 153 and photodetectors 152, and a light sensor 134r located on the frame 115 or lens 118 below or above optical axis 142. In this example, the display optical system 14 includes a light guide optical element 112 as the reflective element for directing the images into the wearer's eye and is situated between an additional see-through lens 116 and see-through lens 118. As reflecting element 124 is within the lightguide optical element and moves with the element 112, an embodiment of a microdisplay assembly 173 is attached on the temple 102 in this example to a display adjustment mechanism 203 for the display optical system 14 embodied as a set of three axis mechanism 203 with shafts 205 include at least one for moving the microd...

fourth embodiment

[0084]FIG. 5D is a top view of a movable display optical system of a see-through, near-eye, device including an arrangement of gaze detection elements. This embodiment is similar to FIG. 5C's embodiment including a light guide optical element 112. However, the only light detectors are the IR photodetectors 152, so this embodiment relies on glint detection only for gaze detection as discussed in the examples below.

[0085]In the embodiments of FIGS. 5A-5D, the positions of the gaze detection elements, e.g. the detection area 139 and the illuminators 153 and photodetectors 152 are fixed with respect to each other. In these examples, they are also fixed in relation to the optical axis of the display optical system 14.

[0086]In the embodiments above, the specific number of lenses shown are just examples. Other numbers and configurations of lenses operating on the same principles may be used. Additionally, in the examples above, only the right side of the see-through, near-eye, head mounted...

Abstract

A see-through, head mounted display and sensing devices cooperating to provide feedback on food items detected in the device field of view. Feedback can include warnings based on personal wearer needs, general nutrition information, food consumption tracking and social interactions. The system includes one or more processing devices in communication with display and the sensors which identify food items proximate to the apparatus, determine feedback information relevant to a wearer of the apparatus; and render feedback information in the display.

Description

PRIORITY CLAIM[0001]This application is a continuation of and claims priority to U.S. patent application Ser. No. 13 / 689,293, filed Nov. 29, 2012, which is incorporated herein by reference.BACKGROUND[0002]People are generally not aware of the nutritional information on food items they consume. While people may have general knowledge of the food items, calorie content, ingredients, and the benefits and consequences of the food they are presented with, tracking consumption and nutritional information for each meal is tedious. Providing nutritional information is advantageous for people trying to watch their weight, people with allergy restrictions, or strict dietary needs.[0003]Mixed reality displays allow virtual imagery to be mixed with a real world physical environment in a display. Systems for mixed reality may include, for example, see through head mounted displays or smart phones with built in cameras that detect the area within a field of view of a wearer. Such systems typicall...
