The present disclosure relates to methods and apparatuses for identifying an object of interest of a user. One example method includes obtaining information about a line-of-sight-gazed region of the user and an environment image corresponding to the user, obtaining information about a first gaze region of the user in the environment image based on the environment image, where the first gaze region is used to indicate a sensitive region determined by using a physical feature of a human body, and obtaining a target gaze region of the user based on the information about the line-of-sight-gazed region and the information about the first gaze region. The gaze region is used to indicate a region in which a target object gazed by the user in the environment image is located.

A head up display system, a control method thereof and a vehicle are provided. The head up display system includes an imaging device group, a concave reflective element, a directional imaging device and a processor, the imaging device group includes at least one single-layer imaging device; the directional imaging device includes a light source device, a direction control element, a diffusing element and a light modulating layer; the processor is respectively connected with the directional imaging device and the at least one single-layer imaging device in the imaging device group.

A method for fault detection is adapted for a vehicle display fault detection system. The vehicle display fault detection system includes a vehicle system and a display system. The method for fault detection includes following steps: detecting whether a first state of the display system is abnormal or not; when the first state is abnormal, the display system is configured to generate a fault detection signal; classifying to generate a control signal according to the fault detection signal; and adjusting the first state of the display system to a second state.

In accordance with an exemplary embodiment, a system is provided that includes one or more first sensors, one or more second sensors, and a processor. The one or more first sensors are of a first sensor modality configured to obtain first sensor data pertaining to an occupancy status of one or more seats of a vehicle. The one or more second sensors are of a second sensor modality, different from the first sensor modality, configured to obtain second sensor data pertaining to the occupancy status of the one or more seats of the vehicle. The processor is coupled to the one or more first sensors and the one or more second sensors, and is configured to at least facilitate determining the occupancy status of the one or more seats of the vehicle based on a fusion of the first sensor data and the second sensor data.

Displaced haptic feedback can be provided to a person providing an input on a user interface. The user interface can be operatively connected to a processor. The processor can be configured to receive an input signal from the user interface. Responsive to receiving the input signal, the processor can be further configured to cause a haptic device to be activated. The haptic device can be physically separated from the user interface. The haptic device can provides a haptic feedback to a user interacting with the user interface.

A display system for a vehicle includes a display unit mounted to the vehicle and is selectively operable in a first mode as a holographic display and in a second mode as a mirror. Holographic images may include rear view images obtained from a camera or computer generated graphics. Holographic images are displayed at a virtual image plane behind the display to reduce the operator's eyes accommodation.
