Abstract: A method for mapping an input device to a virtual object in virtual space displayed on a display device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include, based at least in part on the gaze direction being directed to a virtual object in virtual space displayed on a display device, modifying an action to be taken by one or more processors in response to receiving a first input from an input device. The method may further include, thereafter, in response to receiving the input from the input device, causing the action to occur, wherein the action correlates the first input to an interaction with the virtual object.

Abstract: The present invention relates to a highly porous magnesium carbonate and method of production thereof. The method according to the invention provides a way to control the average pore size of the highly porous magnesium carbonate by controlling the agglomeration of CO2 in a powder formation step in a sol-gel based production process. The method makes it possible to adapt the average pore size to a second material, for example a pharmaceutical compound, to be loaded into highly porous magnesium carbonate. The highly porous magnesium carbonate according to the invention comprises mesopores with an average size in the range 10-30 nm.
