Apraxic patients are known for deficits in producing and comprehending skilled movements. Two experiments tested their implicit and explicit knowledge about manipulable objects in order to examine whether such deficits accompany impairment in the conceptual representation of manipulation features. An eyetracking method was used to test implicit knowledge (Experiment 1): participants viewed a vi...

in this study, it was intended to investigate the persian native speakers’ perception of gerunds by three different elicitation techniques i.e., written, audio, and pictorial through translation. eighty intermediate learners of english were asked to select persian translation of the gerund formsin these elicitation techniques. they were asked to choose one option from a pair of written first la...

The visual analysis of human manipulation actions is of interest for e.g. human-robot interaction applications where a robot learns how to perform a task by watching a human. In this paper, a method for classifying manipulation actions in the context of the objects manipulated, and classifying objects in the context of the actions used to manipulate them is presented. Hand and object features a...

In the field of deformable object manipulation, planning and manipulation methods have long been studied separately. Yet, to put together these methods to implement one whole manipulation system, a variety of implementational problems need to be solved. This work presents a new approach to implement a knot tying system. For the planning phase, we used the Knot Planning from Observation (KPO) pa...

This paper focuses on the fundamental deformation effect of soft fingertips as applied in soft-fingered object manipulations. In order to analyze the deformation effect, we first describe the dynamic relation of a two-fingered object manipulation using soft fingertips. From the dynamic relation, we show that the fundamental deformation effect of soft fingertips is essential for soft-fingered ma...

Present techniques for manipulation with an AIBO involve specialized routines written for specific object shapes and domains, such as ball manipulation in RoboSoccer, where fixed sets of key-frames or fixed motion sequences have often been used, which the AIBO performs without feedback, similar to acting out a pre-defined script. This approach is difficult to generalize, and thus the AIBO is un...

In order for a robot to manipulate an articulated object, it needs to know its state (i.e. its pose); that is to say: where and in which configuration it is. The result of the object’s state estimation is to be provided as a feedback to the control to compute appropriate robot motion and achieve the desired manipulation outcome. This is the main topic of this thesis, where articulated object st...

Cartoon animation techniques have previously been used to enhance the illusion of direct manipulation in 2D graphical user interfaces. In particular, animation may be used to convey a feeling of substance to the objects being manipulated by the user. This paper presents an expansion of this concept to 3D graphical object manipulation. A standard set of 3D direct manipulation operations have bee...

This paper addresses issue of flexible object manipulation by using robot arms. The main objective is to establish a suitable control system of the robot for performing flexible object manipulation tasks. A force sensor equipped at the wrist of the robot arm is used to measure the vibration of the flexible object. A vibration control scheme is designed based on linear feedback of vibration meas...

We present an interactive perceptual skill for segmenting, tracking, and kinematic modeling of 3D articulated objects. This skill is a prerequisite for general manipulation in unstructured environments. Robot-environment interaction is used to move an unknown object, creating a perceptual signal that reveals the kinematic properties of the object. The resulting perceptual information can then i...
