Patent number: 8890814Abstract: An input device enabling a computer user to provide a range of inputs. The device comprises a body made up of a lower portion and an upper portion; an output interface; and a plurality of movement detectors arranged with the body to detect movements of the input device and based thereon to generate input signals for a computer or other device coupled to the output interface. The movement detectors are arranged to detect rotation about first and second axes defined by rotational movement of the upper portion relative to the lower portion, and movement of a actuatable element carried on one of the lower portion and the upper portion and actuatable independently of the other of the lower portion and the upper portion. The input device further comprises translational movement detectors, enabling a user to further provide three translational inputs.Type: GrantFiled: January 12, 2011Date of Patent: November 18, 2014Assignee: Worthington Sharpe LimitedInventors: Samuel Worthington, David Sharpe
