Abstract
Purpose
Multisensory stimulation is integral to experiential consumption. However, a gap persists between recognition of the importance of multisensory stimulation and the research techniques used to study the effects of such stimulation on consumption experiences. This article draws on sensory anthropology to narrow the gap.
Design/methodology/approach
Sensory anthropology has the potential to help consumer researchers understand multisensory stimulation and its effect on consumption experiences. To highlight this potential, ethnographic fieldwork is reported for two related experiential settings: yacht racing and adventure racing.
Findings
It is shown how consumer researchers can apply concepts and data collection techniques from sensory anthropology to derive powerful insights into consumption experiences. A set of guidelines and examples is derived from the embodied concepts associated with sensory anthropology, namely, kinaesthetic schema, bodily mimesis, the mindful body and local biology. These concepts are used to comprehend how consumers experience sensations phenomenologically, understand them culturally and re-enact them socially.
Practical implications
By acknowledging and engaging the senses, researchers can acquire embodied information that would not be evident from the conventional interview, survey or experimental data. Sensory anthropology adds to what is known from psychological, social and cultural sources to enable organisations to differentiate their offerings by means of the senses and sensory expressions, not only in yacht and adventure racing but potentially in many other experiential settings, such as travel, shopping, entertainment and immersive gaming.
Originality/value
This article offers distinct and original methodological insights for consumer researchers by focusing on concepts and data collection techniques that assist the study of experiential consumption from an embodied and corporeal perspective.

Abstract
Operation Vulcan is a survey of the state of the art in training for manual, craft or physical skills. This is the traditional area of training expertise: companies and countries usually take this aspect of training to a fairly advanced stage before they consider extending their inâcompany training activities into other fields such as management training and clerical training. Even today in Britain, this is the only form of training in which some companies engage. When small companies assemble together in group training schemes it is usually for the purpose of pooling their efforts in craft training. Historically craft training precedes technological and technician training by several decades. Here we have, then, the traditional training area. But it is important from another point of view: it is also the biggest training area in the sense that more people are trained in manual and physical skills than in other aspects. These facts make it all the more remarkable that the training revolution in physical skills has yet to happen. We have seen a revolution taking place in management training and, to a less extent, in commercial and clerical training, but in the sphere of physical skills things tend to jog along just as they ever did. We have, it is true, seen âSitting Next to Nellieâ giving way to offâtheâjob training workshops; we have the module system which enables the individual to build up his own unique personal repertoire of skills designed to meet his own needs. We have skills analysis, but this is only vaguelyâcomprehended and only partiallyâdigested. In no way, at present, is skills analysis seen as one of the indispensable fundamentals on which skill training should be built. A great deal of existing training in this field relies on getting yourself a good syllabus and then using this as the basis for instructing by telling and demonstrating. It is almost as though the sheer ponderous deadâweight of tradition linked with the huge scale of the problem has absorbed whatever electric shocks could be administered by the technical innovators and the reformers. And yet, all the components of a comprehensive, rational and analytical system of skill training exist at this moment. Operation Vulcan is an attempt to collect the scattered and random elements and assemble them in some coâordinated form.

Abstract
This paper analyzes the design of a forceâbased impedance control for a haptic interface system characterized by a parallel kinematics. By exploiting the features of parallel mechanisms, which perform better than the serial ones in terms of dynamic performance, stiffness and position accuracy, and by implementing a closedâloop force control, the transparency of a haptic master system and the fidelity of resultant force feedback can be consistently improved. Issues for design and control as well as aspects of performance evaluation of haptic interfaces are treated within the paper and some results of the experimental characterization of a haptic interface are presented.

Abstract
Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties â to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

Abstract
Purpose
To outline and present a generalised scheme for using âlayered methodsâ in foresight work.
Design/methodology/approach
A number of different approaches to âlayeringâ in futures studies and foresight work are examined and synthesised into a generalised scheme. The place of layered methods in foresight work is also examined, and the role of perceptual filters in interpretation is discussed.
Findings
A schema of four major âstrataâ, each potentially containing multiple subâlayers, is developed. The strata range from, for example, shortâterm trends in the shallowest level, through to longâterm macrohistorical forces at the deepest level.
Practical implications
The generalised scheme enables the practitioner to progressively move to greater levels of understanding as new layers of meaning are uncovered or constructed, as appropriate to the specific nature of the particular foresight engagement. The scheme also represents a template from which purposeâbuilt interpretive frameworks can be constructed, as needed, in foresight processes and work.
Originality/value
This paper provides a new, generalised and integrated approach to the use of interpretive frameworks in foresight work.

Abstract
Purpose
In this study, a new methodology to evaluate the performance of physics simulation engines (PSEs) when used in haptic virtual assembly applications is proposed. This methodology can be used to assess the performance of any physics engine. To prove the feasibility of the proposed methodology, two-third party PSEs â Bullet and PhysXtm â were evaluated. The paper aims to discuss these issues.
Design/methodology/approach
Eight assembly tests comprising variable geometric and dynamic complexity were conducted. The strengths and weaknesses of each simulation engine for haptic virtual assembly were identified by measuring different parameters such as task completion time, influence of weight perception and force feedback.
Findings
The proposed tests have led to the development of a standard methodology by which physics engines can be compared and evaluated. The results have shown that when the assembly comprises complex shapes, Bullet has better performance than PhysX. It was also observed that the assembly time is directly affected by the weight of virtual objects.
Research limitations/implications
A more comprehensive study must be carried out in order to evaluate and compare the performance of more PSEs. The influence of collision shape representation algorithms on the performance of haptic assembly must be considered in future analysis.
Originality/value
The performance of PSEs in haptic-enabled VR applications had been remained as an unknown issue. The main parameters of physics engines that affect the haptic virtual assembly process have been identified. All the tests performed in this study were carried out with the haptic rendering loop active and the objects manipulated through the haptic device.

Abstract
Purpose
Sensorless passive lead-through programming (LTP) is a promising physical human-robot interaction technology that enables manual trajectory demonstrations based on gravity and friction compensation. The major difficulty lies in static friction compensation during LTP start-up. Instead of static friction compensation, conventional methods only compensate for Coulomb friction after the joint velocity exceeds a threshold. Therefore, conventional start-up external torques must overcome static friction. When the static friction is considerable, it is difficult for conventional LTP to start up and make small movements. This paper aims to decrease the start-up external torque and improve the small movement performance.
Design/methodology/approach
This paper reveals a novel usage of a high-gain position-loop in industrial robot applications aimed at sensitively detecting external torque during start-up. Then, the static friction is partly compensated by Coulomb friction to facilitate start-up. In addition, a detailed transition method between the proposed start-up and conventional passive LTP is proposed based on a finite state machine.
Findings
Experiments are implemented on the ROKAE XB4 robot to verify the effectiveness of the proposed external torque detection. Compared with the conventional LTP method, the proposed LTP method significantly decreases the start-up external torque and facilitates small movements.
Originality/value
This paper proposes and verifies a novel start-up method of sensorless LTP based on a start-up external torque detection and a transition method between start-up and conventional LTP. This research improves the LTP start-up performance, especially for industrial robots with large static friction.

Abstract
Purpose
The working hypothesis, on which this paper is built, is that it is advantageous to look at protocols of robot rehabilitation in the general context of human-robot interaction in haptic dyads. The purpose of this paper is to propose a new method to detect and evaluate an index of active participation (AC index), underlying the performance of robot-assisted movements. This is important for avoiding the slacking phenomenon that affects robot therapy.
Design/methodology/approach
The evaluation of the AC index is based on a novel technique of assistance which does not use constant or elastic forces but trains of small force impulses, with amplitude adapted to the level of impairment and a frequency of 2âHz, which is suggested by recent results in the field of intermittent motor control. A preliminary feasibility test of the proposed method was carried out during a haptic reaching task in the absence of visual feedback, for a group of five stroke patients and an equal group of healthy subjects.
Findings
The AC index appears to be stable and sensitive to training in both populations of subjects.
Originality/value
The main original element of this study is the proposal of the new AC index of voluntary control associated with the new method of pulsed haptic interaction.
