TL;DR: A wearable system to provide situational awareness for blind and visually impaired people using techniques from computer vision and motion planning to identify walkable space, plan step-by-step a safe motion trajectory in the space, and recognize and locate certain types of objects.
Abstract: This work introduces a wearable system to provide situational awareness for blind and visually impaired people. The system includes a camera, an embedded computer and a haptic device to provide feedback when an obstacle is detected. The system uses techniques from computer vision and motion planning to (1) identify walkable space; (2) plan step-by-step a safe motion trajectory in the space, and (3) recognize and locate certain types of objects, for example the location of an empty chair. These descriptions are communicated to the person wearing the device through vibrations. We present results from user studies with low- and high-level tasks, including walking through a maze without collisions, locating a chair, and walking through a crowded environment while avoiding people.

TL;DR: This paper will investigate how nonlinear mass/spring/damper virtual environments can be designed to guarantee the absence of oscillations and other chaotic behavior in the signal presented to the human operator.
Abstract: Design of haptic systems that guarantee stable interaction is a challenging task. Virtual environments are typically highly nonlinear-resulting in a nonpassive discrete-time model. This paper will investigate how nonlinear mass/spring/damper virtual environments can be designed to guarantee the absence of oscillations and other chaotic behavior in the signal presented to the human operator. In particular, delayed and nondelayed implementation of the mass/spring/damper virtual environment is considered, revealing a nonintuitive result with regard to the allowable local stiffness.

TL;DR: A tele-nanorobotics system using an atomic force microscope (AFM) as the nanorobot and a bilateral teleoperation control system with virtual impedance approach has been introduced for feeling the nano forces.
Abstract: A tele-nanorobotics system using an atomic force microscope (AFM) as the nanorobot has been proposed. Modeling and control of the AFM cantilever, and modeling of nanometer scale forces have been realized for telemanipulation applications. Besides 3-D virtual reality visual feedback in the user interface, a 1 DOF haptic device has been constructed for nano scale haptic sensing. For feeling the nano forces, a bilateral teleoperation control system with virtual impedance approach has been introduced. Initial experiments and simulations on the AFM and teleoperation system show that the system can be utilized for different tele-nanomanipulation applications such as 2-D nano particle assembly or biological object manipulation.

TL;DR: The results show that the best repartition of control in terms of cooperation between human and machine can be identified through an analysis of the steering wheel reversal rate, the steering effort and the mean lateral position of the vehicle.
Abstract: This study investigated human-machine cooperation when driving with different degrees of a shared control system. By means of a direct intervention on the steering wheel, shared control systems partially correct the vehicle's trajectory and, at the same time, provide continuous haptic guidance to the driver. A crucial point is to determine the optimal level of steering assistance for effective cooperation between the two agents. Five system settings were compared with a condition in which no assistance was present. In addition, road visibility was manipulated by means of additional fog or self-controlled visual occlusions. Several performance indicators and subjective assessments were analyzed. The results show that the best repartition of control in terms of cooperation between human and machine can be identified through an analysis of the steering wheel reversal rate, the steering effort and the mean lateral position of the vehicle. The best cooperation was achieved with systems of relatively low-level haptic authority, although more intervention may be preferable in poor visibility conditions. Increasing haptic authority did not yield higher benefits in terms of steering behavior, visual demand or subjective feeling.

TL;DR: A glove is developed that transforms visual information into haptic feedback using small pager motors attached to the tip of each finger that allows a blind player to play Guitar Hero.
Abstract: Very few video games have been designed or adapted to allow people with vision impairment to play. Music/rhythm games however are particularly suitable for such people as they are perfectly capable of perceiving audio signals. Guitar Hero is a popular rhythm game yet it is not accessible to the visually impaired as it relies on visual stimuli. This paper explores replacing visual stimuli with haptic stimuli as a viable strategy to make games accessible. We developed a glove that transforms visual information into haptic feedback using small pager motors attached to the tip of each finger. This allows a blind player to play Guitar Hero. Several tests have been conducted and despite minor changes to the gameplay, visually impaired players are able to play the game successfully and enjoy the challenge the game provides. The results of the study also give valuable insights on how to make mainstream games blind-accessible.
