Abstract: A pressure detection device of detecting a forced state of a deformable object includes a body, an image sensor and a processor. The body is a deformable hollow structure. The body has an inner surface and an outer surface, and an identifiable vision feature is disposed on the inner surface. The image sensor is disposed inside the body and faces the inner surface of the body, and is adapted to capture a frame containing the identifiable vision feature on the inner surface. The processor is electrically connected with the image sensor, and adapted to analyze position variation of the identifiable vision feature within the captured frame for identifying a motion type of a gesture applied to the outer surface of the body.

Abstract: The disclosure is related to a method and a system for obstacle detection adapted to a self-guiding machine. The method is performed in the system including a controller for driving the system, a light emitter, a light sensor, an image processor and a central processor. The light emitter and the light sensor are set apart at a distance. When the light emitter emits an indicator light being projected onto a path the self-guiding machine travels toward, the light sensor senses the indicator light. An image containing the indicator light is generated. After analyzing the image, at least one feature of the indicator light being sensed can be obtained and used to obtain a spatial relationship between the self-guiding machine and an obstacle. The spatial relationship allows the system to determine if the self-guiding machine will collide with a wall or fall from a cliff.

Abstract: An optical detection device includes a substrate, a housing, an optical modulating component, an optical sensor and a cover. The housing is disposed on the substrate and includes a first aperture. The housing is unvaried due to inspection standard or design requirement of the optical detection device. The optical modulating component is disposed on the housing and aligning with the first aperture. The optical sensor is disposed on the substrate and adapted to receive an optical signal passing through the optical modulating component and the first aperture. The cover is disposed on the housing to cover the first aperture. The cover is replaceable for attaching the cover varied for the inspection standard or the design requirement to the unvaried housing in response to a surface of the cover opposite to the housing matched and engaged with a light penetrating area on the optical navigation apparatus.
