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. An orientation (or position) of the accessory device relative to the host computing device may then be computed based on the combined spatial position/orientation for the host computing device and the ascertained spatial position/orientation for the accessory device. The relative orientation that is computed may then be used in various ways to control behaviors of the host computing device and/or accessory device.

A switch is constituted by a movable conductive portion and a pair of fixed conductive portions. The fixed conductive portions are arranged on a substrate, and are each constituted by at least one strip member. A first main conductive pattern and a second main conductive pattern are arranged on the substrate in correspondence with the fixed conductive portions. The movable conductive portion electrically shorts the pair of fixed conductive portions upon coming into contact with both of them. The strip members that constitute the fixed conductive portions each have a first end portion and a second end portion in the extending direction, and the end portions are electrically connected to the corresponding main conductive patterns.

A key input device includes keys and a member having surfaces parallel to each other, the surfaces each having at least one first through hole among first through holes. The keys are inserted to the corresponding first through holes. The member has a first end side, a second end side, a third end side, and a fourth end side, the first end side being opposite the second end side, the third end side being perpendicular to the first end side and opposite the fourth end side. The surfaces of the member are flat from the first end side toward the second end side. The member has a step between a surface on the third end side and a surface on the fourth end side among the surfaces.
