1 Abstract The lack of force feedback in visual-only simulations may seriously hamper user proprioception, effectiveness and sense of immersion while manipulating virtual environments. Haptic rendering, the process of feeding back force to the user in response to interaction with the environment is sensitive to delay and can become unstable. In this paper we will describe various techniques to ...

While visual feedback is dominant in Virtual Environments, the use of other modalities like haptics and acoustics can enhance believability, immersion, and interaction performance. Haptic feedback is especially helpful for many interaction tasks like working with medical or precision tools. However, unlike visual and auditory feedback, haptic reproduction is often difficult to achieve due to ha...

Abstract. This paper addresses the stability of time-delayed force-reflecting displays used in virtual reality interactive systems. A novel predictive-like approach is proposed. The developed solution is stable and robust. Neither time delay estimation nor time delay behavior’s knowledge are required. The controller applies to constant or time-varying delays without any adaptation. In this rese...

This paper outlines the development and evaluation of a wearable haptic game interface. The device differs from many traditional haptic feedback implementation in that it combines vibrotactile feedback with gesture based input, thus becoming a two way conduit between the user and the virtual environment. The device is intended to challenge what is considered an “interface” and sets out to purpo...

The fingertips are one of the most important and sensitive parts of our body. They are the first stimulated areas of the hand when we interact with our environment. Providing haptic feedback to the fingertips in virtual reality could, thus, drastically improve perception and interaction with virtual environments. In this paper, we present a modular approach called HapTip to display such haptic ...

 The Organization Readiness of Engineering Project Management Based on Virtual Teams has been analyzed in an Iranian Engineering firm. Adapting and analyzing the latest readiness model, experts’ opinions were received by questionnaires and main criteria of the readiness have been identified. The considered readiness criteria are: Infrastructure, Deliverables (Drawings, Reports, Minutes of Meeti...

Modern computer-aided design (CAD) technology is widely used in the field of fashion design. Designers do not have to draw again every time they carry out template design, but can and change graphic drawings directly on computer using CAD technology. In this way, designer see fitting effect two-dimensional clothing three-dimensional human body real process garment results according pieces. Then...

Every major milestone in the history of science, technology and interaction design has stemmed from collision human nature (Katona, 2021). From original paper tape punching, it evolved to keyboard input, now touch operation, voice control, recognition, advanced gesture motion capture, eye recognition technologies, so on. In future, brain-computer interfaces mind will also be implemented. Each t...

The evolution of software engineering, multitasking environment, object oriented programming and symbolically assisted simulation methods have enable the creation of interactive simulation environments that come close to providing a virtual experience of the actual system. The initial attempts at utilizing this technology are impressive and yet the degree to which they achieve virtual status is...
