Identifying Kinematic Cues for Action Style Recognition
نویسنده
چکیده
Recognition of emotional states from other’s actions is one of key capability for smooth social interaction. The present study provides a computational-theory-level analysis on which feature may take a crucial role in recognition of emotional attributes in human actions represented as point-light display. Lead by the previous theoretical works and empirical findings, the velocity and acceleration profile was investigated as a major feature of emotional attributes classification. The results showed that emotional attributes in actions as well as action types could be identified by covariance of velocity profiles among multiple body parts. Since, despite different velocity profiles in different actions, these features for emotional attributes were found commonly in multiple different actions, it suggests that the action styles may be mediated by an information channel parallel to action types per se.

Narrative versus Style: Effect of Genre Typical Events versus Genre Typical Filmic Realizations on Film Viewers' Genre Recognition
This study investigated whether film viewers recognize four basic genres (comic, drama, action and nonfiction) on the basis of genre-typical event cues or of genretypical filmic realization cues of events. Event cues are similar to the narrative content of a film sequence, while filmic realization cues are similar to stylistic surface cues of a film sequence. It was predicted that genre recogni...
متن کاملSensorimotor Coarticulation in the Execution and Recognition of Intentional Actions
Humans excel at recognizing (or inferring) another's distal intentions, and recent experiments suggest that this may be possible using only subtle kinematic cues elicited during early phases of movement. Still, the cognitive and computational mechanisms underlying the recognition of intentional (sequential) actions are incompletely known and it is unclear whether kinematic cues alone are suffic...

The purpose of this investigation was to examine the differences between novice and skilled baseball players to anticipate the type of ball being pitched and to specify the players’ dependence on distributed or local kinematic spatial cues. Male baseball players (N= 15; Mage: 27.73 ± 6.28 years; baseball experience: 7.90 ± 5.69 years) and novices (N= 15; Mage: 23.10 ± 5.68 years; no playing exp...
متن کاملSurgical Gesture Segmentation and Recognition
Automatic surgical gesture segmentation and recognition can provide useful feedback for surgical training in robotic surgery. Most prior work in this field relies on the robot's kinematic data. Although recent work [1,2] shows that the robot's video data can be equally effective for surgical gesture recognition, the segmentation of the video into gestures is assumed to be known. In this paper, ...
متن کاملMultisensory perception of action in posterior temporal and parietal cortices.
Environmental events produce many sensory cues for identifying the action that evoked the event, the agent that performed the action, and the object targeted by the action. The cues for identifying environmental events are usually distributed across multiple sensory systems. Thus, to understand how environmental events are recognized requires an understanding of the fundamental cognitive and ne...
