This design paper describes the development of custom built interface between a force-replicating virtual reality (VR) haptic interface glove, and a user. The ability to convey haptic information – both kinematic and tactile – is a critical barrier in creating comprehensive simulations. Haptic interface gloves can convey haptic information, but oft...

Here instead of talking about the signs (that is just the application), I would talk more in general of two arbitrary positions.
The design of a five-fingered wristed robotic hand is discussed. The robot is capable of showing two signs with fingers using a kinematic synthesis technique and one revolute joint per finger.
The resulting candidate des...

... UX studies often involve advanced technologies and systems such as VR or AR. However, many of these studies aim at investigating the performance of such technologies (e.g., sense of presence and interactivity) rather than focusing on the represented product itself (Gaffary et al. 2017;Eroglu et al. 2018;Kwon et al. 2019;Shor et al. 2019;Kim et al. 2020) (hereinafter, issue instruments). ...
User experience (UX) application in the practice of engineering and product design is still limited. The present paper provides insights into research on UX design and recommendations for design practitioners by pointing out common criticalities. These outcomes are achieved through a literature review on how UX relates to design. First, issues in benefitting from UX understanding in design are identified with a specific focus on theoretical contributions. Second, experimental papers investigating UX and design are analysed in relation to previously identified issues. Although issues are present to some extent in all the contributions, the empirical studies dealing with UX in design are overall valid. The results highlight UX’s support in revealing design requirements, but its capability of steering design processes is arguable, as concrete guidelines for practitioners are not well described. Based on identified issues, the authors propose a checklist to make UX studies in design more reliable and their outcomes more comparable.
... However, it might still be quite hard to distinguish similar types of plastics and this technology does not yet allow to trigger all senses and experience all experiential levels, as for example, exploring the flexibility or softness of a certain material. Perhaps, the development of haptic gloves (Shor et al., 2018) can enable touch and tactile feedback in virtual reality, and as such, offer potential in experiential material characterization as well. ...
How do consumers experience the materials in products around them? And how can we capture these experiential qualities of materials into information for designers? These questions initiated this thesis. Over the past four years, we have explored how we can study materials experiences of different types of consumers, to support designers in their materials selection process by understanding the targeted users’ material desires for the designed product. We currently live in a world with an abundance of products and varieties on the market, which complicates the purchase decision for consumers. To satisfy demanding consumers, products must meet both functional requirements and hedonic user needs. A product should work well, safely and simply, plus it must also enhance the user’s life, provide satisfaction and pleasure. Without materials, no products can exist. Thus, materials form the visual and tactile interface with the world around us, and fulfil a part of the functional and hedonic needs. We interact with products through materials , and it is through our senses that we experience materials. In order to foster the user-centeredness of the product development discipline, materials should not be studied in isolation, but incorporate people and their relationship with materials. Central to this research was the exploration of experiential characterization of materials, integrating both the physical representation of materials and the segmentation of different types of consumers. The thesis consists of four major parts: (i) experiential characterization in product design, (ii) material demonstrator form, (iii) consumer segmentation, and (iv) guidelines for experiential material characterization, and theoretical and designerly conclusions. The first part offers insight in the world of experiential characterization studies in the materials and design domain, and the methodological challenges involved in studying materials experience. It reveals learnings on six needs for future research. The second part addresses one of these needs, and explores the appropriate physical representation of materials for experiential characterization studies. The third part focusses on the need of including extensive user aspects, and examines how consumers can be clustered in meaningful segments that prefer different material qualities. The fourth and final part includes guidelines on how to set-up experiential material characterization experiments based on the previous findings, as well as the theoretical and designerly conclusions of this thesis. It closes with future research perspectives and a future vision for design.
... A second limitation is that we only address a single submodality of haptic feedback, namely cutaneous feedback ignoring that the immersion and realism of haptic feedback are driven by the user's multimodal and cross-sensory engagement or stimulation [126]. Indeed, the combination of feedback demonstrated by morphing surfaces shows how augmentation or combination of multiple LoFi feedback can increase a haptic actuator's true fidelity. ...
After decades of research and development, haptic feedback is increasingly appearing in consumer products. While the prevalence of haptic feedback is increasing, the integration rarely offers increased fidelity to previous generations. We argue this is because of the tremendous complexity of successful haptic design engineering, but critically, also because of information saturation. With novel cutaneous feedback technologies and companies emerging almost daily, the multi-disciplinary nature of haptics and the marketing-driven terminology used to stand out in a crowded market makes it challenging to select and integrate actuators correctly. To manage this complexity and facilitate the interdisciplinary exchange of user requirements and material affordances, we introduce a novel classification criterion for haptic actuators focused on the bandwidth and fidelity of potential effects. We introduce vocabulary for describing the precise experience the actuators and corresponding systems should deliver. This same criterion and language can also prove valuable for steering near-future technology development of new and improved actuators and enabling novice and experienced practitioners to understand and integrate cutaneous feedback in their products.
Smart gloves have been under development during the last 40 years to support human-computer interaction based on hand and finger movement. Despite the many devoted efforts and the multiple advances in related areas, these devices have not become mainstream yet. Nevertheless, during recent years, new devices with improved features have appeared, being used for research purposes too. This paper provides a review of current commercial smart gloves focusing on three main capabilities: (i) hand and finger pose estimation and motion tracking, (ii) kinesthetic feedback, and (iii) tactile feedback. For the first capability, a detailed reference model of the hand and finger basic movements (known as degrees of freedom) is proposed. Based on the PRISMA guidelines for systematic reviews for the period 2015–2021, 24 commercial smart gloves have been identified, while many others have been discarded because they did not meet the inclusion criteria: currently active commercial and fully portable smart gloves providing some of the three main capabilities for the whole hand. The paper reviews the technologies involved, main applications and it discusses about the current state of development. Reference models to support end users and researchers comparing and selecting the most appropriate devices are identified as a key need.
