A swapping utility enables directional commands from a graphic user interface and/or keyboard to be utilized to swap data items associated with lists, tables or other series of data items. Upon receipt of both a directional command, e.g. up, down, left, or right, and a swap command, the utility uses the current position of the cursor or a selected entity to identify a first data item to be swapped and the relative direction thereto to identify a second, adjacent data item to be swapped. If both identified data items are of the same data type, their respective contents are exchanged within the ordered list or table without the need to cut and paste the content. In alternative embodiments, multiple adjacent data items may be swapped, or, in an embodiment which utilizes multiple selection icons, single or multiple nonadjacent entities may be directly swapped.

Sensor fusion algorithm techniques are described. In one or more embodiments, behaviors of a host device and accessory devices are controlled based upon an orientation of the host device and accessory devices, relative to one another. A combined spatial position and/or orientation for the host device may be obtained based on raw measurements that are obtained from at least two different types of sensors. In addition, a spatial position and/or orientation for an accessory device is ascertained using one or more sensors of the accessory device.

A system and method for calibrating rigid and non-rigid arrays of 3-axis magnetometers as disclosed. Such arrays might be used to analyze structures containing ferromagnetic material. The calibration determines scale factor and bias parameters of each magnetometer in the array, and the relative orientation and position of each magnetometer in the array. Once the parameters are determined, the actual magnetic field value at the magnetometer location can be simply related to magnetometer measurements. The method and system can be used to calibrate an array of 3-axis magnetometers in aggregate as opposed to individual magnetometers. This is critical in large arrays to increasing reproducibility of the calibration procedure and decreasing time required to complete calibration procedure.
