An interactive TV content creation tool imports video and other assets, including WebPages, Java script, etc., as a series of resources for interactive TV content creation for real time audience estimation and program ratings. A processing system embeds hyperlinks into one or more objects contained in a program frame as desired. Each hotlink has attributes. These attributes include shape, name, description and Z-order. The hotlink can have one of several shapes, including rectangle, ellipse and parallelogram. The hotlink types are included in an object tree which is displayed in a window to a creator. A hotlink type is selected in the hotlink tree, and a window displays a linked properties tab available for the selected object. There are several link types available; linking to a URL, another interactive TV content file, a video clip, an audio clip, an image, or a tracking action and transaction action. There are different parameters for different actions. One parameter is a tracking script. Another parameter is a tracking flag. The tracking flag can be set to follow different tracking modes. If the "enable global tracking" is chosen, a name/value pair "global=true" will be appended to the tracking script transmitted to the global tracking server through network. If the "enable local tracking" is chosen, a name/value pair "local=true" will be appended to the tracking script. The embedded tracking information can follow three multi-level tracking patterns (MTP): regular program viewing tracking, enhanced program viewing tracking, and per object granularity tracking. The viewer returns the script to a server which calculates audience estimation and program ratings for the interactive TV program.

An actuator device (2) includes a piezoelectric or electro-strictive solid state actuator element (6) that is elongated upon application of an electric voltage thereto, and a transmission mechanism (8) that amplifies the stroke displacement of the actuator element. The transmission mechanism (8) includes a plurality of rigid frame members (12), including unitary frame members (12.1, 12.2) and divided frame members (12.3), and elastically flexible joints (10) that respectively interconnect the frame members. Each one of the divided frame members (12.3) is made up of a plurality of separate parallel link rods (16). Each flexible joint (10) is made up of a plurality of individual parallel hinge members (18) that respectively connect an end of each one of the link rods (16) to the adjacent unitary frame member (12.1, 12.2). By this division of the flexible joints and of the divided frame members into parallel sub-components, the cross-sectional thickness of each individual hinge member is reduced, and thereby the bending stiffness and the outer fiber strain of the material of the hinge members is significantly reduced while providing the same total tensile strength and tensile stiffness. The link rods of each divided frame member effectively form a parallelogram linkage for moving and guiding the output members (12.1) in a parallel manner.
