Claim 0:
1. A method in an electronic device, the method comprising:
detecting, with one or more processors, a communication device electronically in communication with a content presentation companion device operating as a primary display for the electronic device using a content redirection feature where content presented on the content presentation companion device where content is received by one or more other processors of the electronic device from a remote electronic device and then redirected to the content presentation companion device for presentation and comprising a first ultra-wideband component;
determining, with a second ultra-wide component carried by the electronic device, a distance between the electronic device and the content presentation companion device using an ultra-wideband ranging process;
dynamically enhancing, with the one or more processors, a user interface of the content presentation companion device as a function of the distance between the electronic device and the content presentation companion device, the enhancing adjusting a user interface feature being presented on the content presentation companion device; and
causing, by the one or more processors, presentation of a magnification element magnifying a presentation characteristic of content situated within a perimeter of the magnification element as a function of the distance;
the user interface feature comprising a dynamic user interface feature and the magnification element comprising a virtual magnifying glass;
the dynamic user interface feature comprising a pointer size of a pointer being presented on the content presentation companion device; and
further comprising:
detecting, with a motion detector carried by the electronic device, an amount of motion of the electronic device in three-dimensional space;
in response to detecting the amount of motion of the electronic device;
adjusting, with the one or more processors, a speed of movement of the pointer as a combined function of the distance and the amount of motion of the electronic device in the three-dimensional space; and
causing motion of the virtual magnifying glass along the primary display as a function of the distance and in proportion to the motion of the electronic device in the three-dimensional space;

determining, with an antenna array carried by the electronic device, an angle of arrival at which signals delivered by the communication device to the content presentation companion device intersect a major face of the content presentation companion device; and
adjusting a movement sensitivity of the pointer along the content presentation companion device as a function of the angle of arrival; and
wherein a movement amount of the virtual magnifying glass relative to the motion of the electronic device in three-dimensional space is defined as a function of the angle of arrival.
