    Abstract: The invention provides an optical touch device, including a main body, a keyboard and a light emitting member. The keyboard, placed on the main body and having a first end portion and a second end portion, includes a supporting frame, a keycap and a stopping member. The keycap is connected to the supporting frame and moves between a first position and a second position. The stopping member is connected to the keycap and moves simultaneously with the keycap. The light emitting member generates a light beam to the keyboard. When the keycap is in the first position, the light beam passes through the first end portion to the second end portion, and when the keycap is in the second position, the light beam is terminated by the stopping member, such that the light does not reach the second end portion.

    Abstract: An input device is equipped with a cursor pointing unit including a mechanical control stick and an optical sensor. The optical sensor is mounted on the mechanical control stick and has a contact surface for sensing object motion thereon. A cursor signal is generated when the mechanical control stick is inclined by an exerted pressure. When the mechanical control stick is not inclined, a position frame of the object on the contact surface is retrieved as a reference frame. A real-time position frame of the object is retrieved when the object remains on the contact surface. A speed of the object is calculated according to the reference frame and the real-time position frame. When the speed does not exceed a threshold, a cursor position move is generated according to the speed; and when the speed exceeds the threshold, a switch signal is generated to initiate a gesture controlling mode.

    Abstract: A portable electrical device includes a tablet PC, a bottom plate, a support arm and a pivot portion. The tablet PC includes a breach and a first magnetic inducing member arranged inside the breach. One end of the support arm is pivoted to the bottom plate, and the other end of the support arm is pivoted to the pivot portion, and the other end of the pivot portion is with a second magnetic inducing member. When the second magnetic inducing member is moved into the breach to magnetize the first magnetic inducing member, the tablet PC is securely coupled with the pivot portion so that the tablet PC can be rotated; on the contrary, when the second magnetic inducing member is removed from the breach, the tablet PC can be totally independent to the support arm and the bottom plate.

    Abstract: A keyboard device includes an operation surface. One long side of the operation surface is referred to as a proximal side, which nears a user operating the keyboard device; and the other long side is referred to as a distal side. A key unit is positioned on the proximal side, wherein the key unit includes a plurality of keys. A camera module is positioned on the distal side. An angle between a border of a field of view of the light sensor and the operation surface is set at a particular angle thus user's hand lays outside the field of view of the light sensor when the user is manipulating the key unit.
