Disclosed herein are systems and methods for tracking facial expressions efficiently. In one embodiment, a system includes a non-contact head-mounted electro-optical sensor (e.g., an inward-facing head-mounted camera), which measures reflections from a region on a user's head, which are indicative of facial expressions of the user. The system also includes a computer that detects, based on the reflections, a type of facial expression expressed by the user, which belongs to a group comprising neutral facial expressions and non-neutral facial expressions. The computer uses this detection to determine how to proceed to read the electro-optical sensor: the computer reads the electro-optical sensor at a first average bitrate (b) when the user expresses a facial expression from among the neutral facial expressions, and reads the electro-optical sensor at a second average bitrate (b) when the user expresses a facial expression from among the non-neutral facial expressions, where b>b.

Controlling reading of a head-mounted sensor according to facial expressions

Disclosed herein is robust detection of facial expressions that accounts for interferences on the face. In one embodiment, a system includes a head-mounted device that comprises (i) light sources configured to emit light towards a first region on a user's face, and (ii) discrete photosensors, spread over more than 2 cm, which take measurements of reflections of the light from the first region. Additionally, the system includes a head-mounted camera that captures images of a second region on the face. A computer calculates, based on the images, an extent of presence of hair over a portion of the first region. Optionally, the computer calculates extents of other interferences such as perspiration, applied makeup, and skin infection. The computer then detects facial expressions of the user based on the measurements of the reflections and the calculated extent of the hair and/or other interferences.

A novel design for untethered smartglasses with wireless connectivity in which electronic components and electric wiring are mounted in a manner than enables at least a portion of temples of the smartglasses to be bent around the ear to improve the smartglasses' fit. In one embodiment, the smartglasses include a front element that supports lenses and two temples, coupled to the front element through hinges that enable folding and unfolding. At least one of the temples includes: a first portion coupled to the front element with first electronic components, a second portion coupled to the first portion with electric wires, and a third portion coupled to the second portion with second electronic components. The second portion is designed to be bent around a human ear to improve the smartglasses' fit, and the first and third portions are not designed to be bent to improve the smartglasses' fit.

Smartglasses with bendable temples

A safety system that provides specific warnings to an occupant of a vehicle engaged in a certain activity that can cause an adverse outcome in an event of a Sudden Decrease in Ride Smoothness (an SDRS event). The safety system includes a sensor that takes measurements of the vehicle compartment, and a computer that estimates, based on the measurements, whether the occupant of the vehicle is engaged in a certain activity that can lead to an adverse outcome in case of an SDRS event. Responsive to receiving an indication indicative of an imminent SDRS event and estimating that the occupant is engaged in the certain activity, the computer provides a specific warning to the occupant. The specific warning describes a specific action related to the certain activity, which the occupant should take.

Provide specific warnings to vehicle occupants before intense movements

A safety system for an autonomous vehicle that may be used to warn an occupant engaged in a certain activity that involves handling an object that can harm the occupant in an event of a Sudden Decrease in Ride Smoothness (an SDRS event). The safety system includes a camera that takes images of the occupant and a computer that estimates, based on the images, whether the occupant is engaged in the certain activity. The computer receives from an autonomous-driving control system an indication of whether an SDRS event is imminent. Responsive to both receiving an indication of an imminent SDRS event and estimating that the occupant is engaged in the certain activity, the computer commands a user interface to warn the occupant shortly before the SDRS event.
