Indirect multi-touch interaction is described. In an embodiment, a user interface is controlled using a cursor and a touch region comprising a representation of one or more digits of a user. The cursor and the touch region are moved together in the user interface in accordance with data received from a cursor control device, such that the relative location of the touch region and the cursor is maintained. The representations of the digits of the user are moved in the touch region in accordance with data describing movement of the user's digits. In another embodiment, a user interface is controlled in a first mode of operation using an aggregate cursor, and switched to a second mode of operation in which the aggregate cursor is divided into separate portions, each of which can be independently controlled by the user.

A pointing device with independently movable portions is described. In an embodiment, a pointing device comprises a base unit and a satellite portion. The base unit is arranged to be located under a palm of a user's hand and be movable over a supporting surface. The satellite portion is arranged to be located under a digit of the user's hand and be independently movable over the supporting surface relative to the base unit. In embodiments, data from at least one sensing device is read, and movement of both the base unit and the independently movable satellite portion of the pointing device is calculated from the data. The movement of the base unit and the satellite portion is analyzed to detect a user gesture.

A pointing device using proximity sensing is described. In an embodiment, a pointing device comprises a movement sensor and a proximity sensor. The movement sensor generates a first data sequence relating to sensed movement of the pointing device relative to a surface. The proximity sensor generates a second data sequence relating to sensed movement relative to the pointing device of one or more objects in proximity to the pointing device. In embodiments, data from the movement sensor of the pointing device is read and the movement of the pointing device relative to the surface is determined. Data from the proximity sensor is also read, and a sequence of sensor images of one or more objects in proximity to the pointing device are generated. The sensor images are analyzed to determine the movement of the one or more objects relative to the pointing device.

Multi-touch user interface interaction is described. In an embodiment, an object in a user interface (UI) is manipulated by a cursor and a representation of a plurality of digits of a user. At least one parameter, which comprises the cursor location in the UI, is used to determine that multi-touch input is to be provided to the object. Responsive to this, the relative movement of the digits is analyzed and the object manipulated accordingly. In another embodiment, an object in a UI is manipulated by a representation of a plurality of digits of a user. Movement of each digit by the user moves the corresponding representation in the UI, and the movement velocity of the representation is a non-linear function of the digit's velocity. After determining that multi-touch input is to be provided to the object, the relative movement of the representations is analyzed and the object manipulated accordingly.
