Abstract: A method and system for a hydrological process that describes and characterises either statically or temporally, soil moisture variability within agricultural fields, specific to zone-based field recommendations. Surface and subsurface hydrological processes are combined with soil physical properties, electrical conductivity (EC), topography, soil moisture sensors and climate parameters from weather stations, to produce a zone-based soil moisture balance. This process facilitates in-season optimization of crop inputs such as water from irrigation, seed, nutrients, herbicides, or pesticides based on the soil moisture conditions throughout a field.

Abstract: A communication system and a method of communication is disclosed. The system includes a receiver for receiving a signal from a transmitter that is associated with an item, and a processor arranged to infer based on parameters of the received signal a user's psychological state with respect to the associated item. The communication system include a display to display a corresponding image in dependence on the inferred psychological state.

Abstract: A wearable computing device includes at least one processor, a display element configured to display augmented reality (AR) content to a wearer of the wearable computing device and presenting a field of view to the wearer, a location sensor providing location information associated with the wearable computing device, and an augmented reality (AR) engine. The AR engine is configured to identify a location of the wearable computing device and a location of a first device within the environment, receive an operating status of the first device, determine a first AR element associated with the first device based on the operating status of the first device and the location of the first device relative to the location of the wearable computing device, and display the first AR element using the display element, the first AR element is displayed at a display location approximately aligned with or proximate to the location of the first device within the field of view.

Abstract: Some embodiments of the present invention provide touch sensitive image display devices including: an image projector to project a displayed image onto a surface; a touch sensor light source to project a plane of light above the displayed image; a camera to capture a touch sense image from light scattered from the plane of light by an approaching object; and a signal processor to process the touch sense image to identify a location of the object. The light path to the touch sensor camera includes a keystone-distortion compensating topical element, in particular a convex curved aspherical minor.
