When full automation of mobile robots is not possible or desirable, teleoperation constitutes an alternative. The human operator can be supported with direction cues to facilitate localization or navigation. These cues are presented typically in the auditory, haptic and/or visual modality. An experiment was conducted to evaluate systematically and empirically the (uni-modal and multi-modal) effects...
While there is an increased appreciation for integrating haptic feedback with audio-visual content, there is still a lack of understanding of how to quantify the added value of touch for a user's experience (UX) of multimedia content. Here we focus on three main concepts to measure this added value: UX, emotions, and expectations. We present a case study measuring the added value of haptic feedback...
Redirected walking allows users to explore a large virtual environment while there is a limitation of the room size. Previous works tried to present users straight path in a virtual environment while they walked on a curved path in reality. We expand a previous technique to present users a various curved path in a virtual environment while they walked on a particular curved path or a straight path...
Proper integration of sensory cues facilitates 3D user interaction within virtual environments (VEs). Studies showed that the integration of visual and haptic cues follows maximum likelihood estimation (MLE). Little effort focuses however on the mechanism of integrating force and vibrotactile cues. We thus investigated MLE's suitability for integrating these cues. Within a VE, human users undertook...
In this paper, a summary of various sensory technologies and interactions within them in wearable platforms is presented. In the first part of the paper, we discuss the way humans perceive various sensory inputs. Then, we review today's state of art sensor technologies for user interfaces, followed by discussions on opportunities uniquely enabled by the wearable form factor.
This paper presents an experimental evaluation of physical human-human interaction in lightweight condition using a one degree of freedom robotized setup. It explores possible origins of Physical Human-Human communication, more precisely, the hypothesis of a time based communication. To explore if the communication is correlated to time a, statistical state machine model based on physical Human-Human...
Robots could benefit from maps that represent haptic properties of their surroundings. By touching locations with tactile sensors, robots can infer haptic properties of their surroundings, but touching all locations would be prohibitive. We present an algorithm that uses touch and vision to efficiently produce a dense haptic map. Our approach assumes that surfaces near a robot that are visually similar...
When two partners perform a joint physical task, each of them experiences a force that sums together a component generated by the partner and another generated from the environment. To investigate whether subjects are able to distinguish these two components, we created a force perception task in which two partners indicate the direction of an external force applied to a rigid bar that they grasp...
Haptic guidance has previously been employed to improve human performance in control tasks. This paper presents an experiment to evaluate whether haptic feedback can be used to help humans learn a compensatory tracking task. In the experiment, participants were divided into two groups: the haptic group and the no-aid group. The haptic group performed a first training phase with haptic feedback and...
This paper introduces a unique type of mixed reality system based on passive-haptic feedback, which enables its user to manipulate real objects with bare hands while seeing its counterpart in the HMD with more information attached. The system provides users in MR systems with a more realistic sense of touch and costs less money comparing to the active force feedback devices. In this paper, accuracy...
Virtual/mixed reality leveraging an encountered type haptic display will suffer difficulty if virtual and real objects are spatially discrepant. We propose a new method for resolving this issue, visual guidance. The visual guidance algorithm is defined and described in detail, and contrasted with a previously explored approach. The feasibility of the proposed algorithm is experimentally verified.
Nowaday the mobile cell phone technology growing exponentially and it be a fundamaental element of our modern life style. This technology help users to explore and share their activities through various messaging systems regardless of location and time. Messaging via texting is the essence of mobile communication and connectivity. However, it become increasingly difficult for visually impaired to...
The use of multimodality in warning systems has proven to be more effective than any unimodal warning systems, as it lowers the visual workload and provides multiple channels in alerting users. Unfortunately, uni modality is found to be most commonly practiced in warning systems, instead. Literature suggests that audio and haptic multimodal warning systems is the most suitable to be implemented in...
Cardiac auscultation is a cost-effective medical procedure used to examine the heart and obtain information regarding the hearts rate, rhythm, location timing, intensity, quality, and shape. Relying on visual, audio and haptic cues, it is a difficult skill to master and with the availability of various new diagnostic techniques, the emphasis on cardiac auscultation is decreasing in both education...
Autonomous vehicles will significantly change the existing driver-vehicle relationship, since only a destination input from the human driver will suffice. However, reduced degree of human-control could result in lack of driving pleasure and excitement. Thus, we proposed a method to increase the flexibility in controlling of an autonomous vehicle by allowing the driver to control its lateral and longitudinal...
There has been significant research aimed at leveraging programmable robotic devices to provide haptic assistance or augmentation to a human user so that new motor skills can be trained efficiently and retained long after training has concluded. The success of these approaches has been varied, and retention of skill is typically not significantly better for groups exposed to these controllers during...
During the last decade significant advances have been made in vibrotactile actuator design that are leading to the development of novel haptic technologies. Similarly, important innovations have been made in the area of virtual reality for scene rendering and user tracking. However, the integration of these technologies has not been well explored. In this paper, we outline a broad design philosophy...
Multimedia has become an ordinary component of modern software and hardware. Sound, graphics, and animation are present at almost every application of both desktop and mobile platforms. However, human senses cover more than two media. Thus, the transition from Multimedia to Mulsemedia (MULtiple SEnsorial MEDIA) is quite natural. Mulsemedia enriches traditional multimedia content with new media objects,...
This research analyzes if and how the Head Related Transfer Function (HRTF) can be used to support effective Human-Computer Interaction when people in a Virtual Environment (VE) without visual feedback. If sounds can be located in a VE by using HRTF only, designing and developing considerably safer but diversified training environments might greatly benefit individuals with visual impairments. To...
