Capture Techniques

Motion-capture techniques are rarely based on orientation measurements for two main reasons: (1) optical motion-capture systems are designed for tracking object position rather than their orientation (which can be deduced from several trackers), (2) known animation techniques, like inverse kinematics or geometric algorithms, require position targets constantly, but orientation inputs only occasionally. We propose a complete human motion-capture technique based essentially on orientation measurements. The position measurement is used only for recovering the global position of the performer. This method allows fast tracking of human gestures for interactive applications as well as high rate recording. Several motion-capture optimizations, including the multijoint technique, improve the posture realism. This work is well suited for magnetic-based systems that rely more on orientation registration (in our environment) than position measurements that necessitate difficult system calibration.

This chapter analyzes the slow “sorrowful” (de jale) tunes that Roma often associate with crying. Three musical parameters characterize this repertoire: (1) the rhythmic and temporal structure (irregular aksak or unmeasured rhythm); (2) the slight asynchronies between the melody and the harmonic accompaniment, which creates a swinging effect; and (3) the complex elaboration of the melodic line, in particular the addition of ornaments and passing notes to create an effect that is known locally as “sweetness.” The analysis is supported by empirical measurements of timing durations, obtained by tracking the musician’s bow’s movements with motion capture techniques.

Live Action

This article aims to outline the distributed agency within the creation of computer-generated characters for live-action movies that use Motion Capture techniques. This technique requires a tight interplay between human actors, technical artefacts and digital processes. With the help of ANT the relationships within this heterogeneous collective can be presented more precisely in order to assign agency to human and non-human participants. Considerations concerning a combined interplay of humans and computer-driven actions result in the figure of the hybrid actor. Gollum, a computer-generated character from Peter Jackson's adaptation of the Lord of the Rings, serves as case example to carve out the attributes of this composite agent. The aim of the article is to show how these types of agents tackle the film industry's inherent ontology revolving around human actors and their products. The article contributes an insight how the mentioned network reacts to the emerging problem of crediting in the context of Motion Capture as technical innovation and how the involved community preserves their notion of artistry.

Motion Capture Systems

This paper, describes the development of a motion capture system with novel features for biped robots. In general, motion capture is effectively utilized in the field of computer animation. In the field of humanoid robotics, the number of studies attempting to design human-like gaits by using expensive optical motion capture systems is increasing. The optical motion capture systems used in these studies have involved a large number of cameras because such systems use small-sized ball markers; hence the position accuracy of the markers and the system calibration are very significant. However, since the human walking gait is a simple periodic motion rather than a complex motion, we have developed a specialized motion capture system for this study using dual video cameras and large band-type markers without high-level system calibration in order to capture the human walking gait. In addition to its lower complexity, the proposed capture method requires only a low-cost system and has high space efficiency. An image processing algorithm is also proposed for deriving the human gait data. Finally, we verify the reliability and accuracy of our system by comparing a zero moment point (ZMP) trajectory calculated by the motion captured data with a ZMP trajectory measured by foot force sensors.

The Impact

We investigated the impact of Nordic walking (NW) on gait patterns in individuals with Parkinson’s disease (PD) following a 6-week NW familiarization. Twelve participants with PD and 12 healthy older adults took part in a gait analysis walking with and without poles (NP). Results showed larger knee power (knee extensor: K2) on the most affected leg in NW compared to NP (P = .01). On the less affected side, larger power absorption (knee extensor: K3) was found during preswing (K3) compared to older adults in both NP and NW (P = 0.01). NW showed longer stride length and single support time (P < .01) compared to NP. Walking with poles improved gait spatial–temporal characteristics and power profiles at the knee joint both on the less and most affected sides in individuals with PD. NW could be beneficial to help regain a more functional gait pattern in PD.
