Directional data is derived from a manually-interactive-deviceconfigured to generate positional data and intensity data. Initial positional data is generated, along with initial intensity data from an initial contact of a finger upon the manually-interactive-device. The manually-interactive-device has a definition sufficiently high to produce a plurality of data-points in response to the application of a single finger. Directional data is produced in response to a finger rolling or tilting operationby generating additional intensity data in which variations occur to intensity values at the previously identified data-point positions.

Controlling a process by generating intensity values

The detection of multiple manual interactions upon a touch-pad is shown. Drive lines intersect a scan lines and each intersection between a drive line and a scan line includes an element of variable resistance. A scanning processor energises the drive lines and monitors the scan lines. The scanning processor is configured to identify positions of manual interaction, validate identified positions to identify potentially erroneous positions and remove positions identified as erroneous. However, removed positions are re-introduced when they are not in the vicinity of other identified positions.

Detecting multiple manual interactions

Manual selection of an entity from a list of entities displayable by scrolling is facilitated. A list () of selectable entities is established. A range () is identified of selectable entities (ETO E) within the list. A portion () of the range is displayed and output signals are received in response to manually applied pressure. Scrolling is performed through the range, not directly through the list, at a rate related to the manually applied pressure. The range is reduced during the scrolling operation to remove entities that are clearly not to be selected.

Scrolling through a plurality of entities

Illumination functionality is combined with a touch-sensing functionality. A first electrical conductor and a second electrical conductor are located on a substrate. A pressure-sensitive element () is connected across the conductors and a light-emitting device () is also connected between the conductors. A control circuit alternates between energizing the pressure-sensitive element with current flowing in a first direction and driving the light-emitting device with current flowing in an opposite direction.

Touch-sensitive illumination

A detection element () is energised. The detection element is substantially non-conductive without an application of pressure and becomes increasingly conductive in response to pressure application. A processor () is interrupted from a low-power dissipation state in response to a first detectable application of pressure by the detection-element. The processor is then configured to monitor further pressure applied to the same detection element.
