<p>The invention concerns a tiltable board. The board comprises a platform having a first surface (21), a second surface (22) and an outer edge defining a shape. The platform further comprises a supporting element (24), mounted on the second surface of the platform, the supporting element including a pivoting means to allow tilting of the platform from a starting orientation by a user manipulating the platform at least one of a plurality of locations; wherein the shape of the platform results in the platform having differing degrees of maximum tilt relative to the starting orientation depending on the choosen location of manipulation of the platform by the user. The invention further concerns a sensor assembly (28) to be used in conjunction with a tiltable board having a platform able to be manipulated by a user from a starting orientation. The sensor includes a housing; and a sensor, mounted within the housing and operable to produce a sensed output, wherein the sensed output is indicative of the degree of tilt of the platform relative to the starting orientation.</p> |
