Polyester sheets were screen-printed with 16 different patterns formed from one of two types polymer-based ink. The arrays bumps or pockets pitch and per cent coverage People stroked their fingers over the reported resulting feelings in terms 15 prechosen word pairs, ranging psycho-physical smooth-coarse to more impressionable affective artificial-natural happy-sad. It has been possible partially relate printed surfaces' roughnesses sliding friction coefficients against a fingertip. But...
The feel of films, wrapping paper, cardboards, and other packaging materials are important to the commercial success foods. It is known from people's self-report studies that different surfaces provoke subjective responses. There several mechanical parameters, including friction, roughness, compliance, thermal properties, which sensory feel. This paper describes design, construction, use a multi-sensory measurement system for tactile sensation can be used evaluate materials. experiments were...
Surface texture sensation is significant for business success, in particular solid surfaces most of the materials; including foods. Mechanisms roughness perception are still unknown, especially under different conditions such as lubricants with varying viscosities, temperatures, or force loads during observation surface. This work aims to determine effect those unknown factors, applied sensory tests on 62 healthy participants. Roughness fingertip was tested water and diluted syrup solutions...
Tools for eliciting and managing product requirements are now well-established in some fields of engineering. These tools primarily focus on linking objective, functional customer to the product’s properties. Whilst there have been advances identifying human factors requirements, elicitation customers’ subjective a remains challenge. This article reports comprehensive case study use affective engineering elicit moisturizer packaging. The methodology uses groups surveys requirements. results...
Purpose The purpose of this paper is to describe the Kansei engineering toolkit that has been developed provide a set tools and techniques support better packaging design. Design/methodology/approach its foundations in but work extended scope increased reliability results by: including structured linkages designers; replacing “highest level ” from type 1 with brand values; introducing more process for elicitation 2 selection pack physical properties; reducing complexity semantic differential...
Old age is associated with reduced mobility of the hand. To investigate related decline when reaching-to-lift an object we used sophisticated kinematic apparatus to record reaches carried out by healthy older and younger participants. Three objects different widths were placed at three distances, having either a high or low friction surface (i.e. rough slippery). Older participants showed quantitative differences their counterparts – movements slower peak speed did not scale distance. There...
A process for the design and manufacture of 3D tactile textures with predefined affective properties was developed. Twenty four were manufactured. Texture measures from domain machine vision used to characterize digital representations textures. To obtain ratings, touched, unseen, by 107 participants who scored them against natural, warm, elegant, rough, simple, like, on a semantic differential scale. The texture correlated participants' ratings using novel feature subset evaluation method...
Many manufacturers wish to relate the physical properties of their products customers' affective responses so that they can improve design products. Rasch measurement theory is a novel approach in this context could offer business benefits over other approaches. The aim research was determine whether support construction scale measure impression moisturiser cream elicited by compliance moisturiser's packaging. compliances packaging used develop for contents previous were measured. New...
In this work we present a flexible Electrostatic Tactile (ET) surface/display realized by using new emerging material graphene. The graphene is transparent conductor which successfully replaces previous solution based on indium-thin oxide (ITO) and delivers more reliable for bendable displays. electrostatic tactile surface capable of delivering programmable, location specific textures. ET device has an area 25 cm2, consists 130 μm thin optically (>76%) mechanically structure overlaid...
Reach-to-grasp movements change quantitatively in a lawful (i.e. predictable) manner with changes object properties. We explored whether altering texture would produce qualitative the form of precontact movement patterns. Twelve participants reached to lift objects from tabletop. Nine were produced, each one three grip surface textures (high-friction, medium-friction and low-friction) widths (50 mm, 70 mm 90 mm). Each was placed at distances (100 300 500 mm), representing total 27 trial...
Contrasting adjectives have been a common approach for measuring affective responses to products and design elements, but this has often introduced various sources of inaccuracy. Such inaccuracies yield non-linear scales their statistical procedures can present shortcomings. A different is use the Rasch model. The application model as measurement features novel. Thus, research aimed determine whether data from some fit diverse group participants assessed specialness four pieces wrapped...
This paper investigates the effect of maximum indentation force and depth on people's ability to accurately discriminate compliance using indirect visual information only. Participants took part in two psychophysical experiments which they were asked choose `softest' sample out a series presented pairs. In experiments, participants observed computer-actuated tip indent pairs one conditions; (10mm) or (4N). process simulates tool operated palpation laparoscopic surgery. Results used plot...
Our world is filled with texture. For the human visual system, this an important source of information for assessing environmental and material properties. Indeed – presumably reason– system has regions dedicated to processing textures. Despite their abundance apparent relevance, only recently relationships between texture features high-level judgments have captured interest mainstream science, despite long-standing indications such relationships. In study, we explore relationships, as these...
Abstract The Adaptive Neuro‐Fuzzy Inference System (ANFIS) is proposed to simulate and analyze the mapping between physical properties of tactile textures people's affective responses. People were asked rate feeling 37 against six pairs adjectives on a semantic differential questionnaire. friction coefficient, average roughness, compliance, thermal parameter each texture measured. ANFIS models built predict responses textures. resulting demonstrated good match predicted actual responses,...
Abstract We describe a fully programmable Electrostatic Tactile (ET) feedback system that delivers range of tactile textures to mobile display. The ET is robust, thin, and optically transparent structure can be overlaid unobtrusively on top display screen. exploits the phenomenon electrovibration create controllable frictional force between user's fingertip surface. enables realization localized information delivered skin directly, without moving parts. A image formed in accordance with...
