Question is: Based on the data inserted by the user, the tool renders a graph on the computer screen. The interactive drawing gives blind users the opportunity to draw graphs manually.
At the Army's National Automotive Center, the Simulation Throughout the Life Cycle program used haptics to test military ground vehicles under simulated battlefield conditions.
Haptic applications can be used to safely train aircraft and other complicated machinery operators.
Haptic technology allows users to receive haptic feedback while feeling the digital models, or picking up and placing objects such as chairs. Haptics Research Haptic research originates with the work of Heinrich Weber Prytherch, , a 19th century professor at the University of Leipzig. In Lederman and Klatzky Klatzky, , summarized four basic procedures for haptic exploration, each one eliciting a different set of object characteristics: The development of several haptic devices in the early s facilitated important experiments that involve human tactile perception, and improved the understanding of haptic human-computer interaction.
The increasing number of researchers in the haptics domain in the late s contributed to the appearance of a specialized Internet magazine. Haptics-e published haptics-related technical discussions and articles. Since the foundation of Haptics-e and Haptics International Society , numerous conferences, symposiums, and publications were organized, indicating the expansion of the haptics research community. Haptic Devices and Hardware Characteristics In this section we present the most novel haptic devices and we categorize the hardware device characteristics by comparing information from various manufacturers.
The Mimic Mantis has a different design compared to other haptic devices: The user interacts with the system through an integrated keyboard and a two-button grip, which can be changed to satisfy the application requirements.
It uses proprietary resistive bend-sensing technology to accurately transform hand and finger motions into real-time digital joint-angle data. Each of the incorporated sensors is extremely thin and flexible, being virtually undetectable in the lightweight elastic glove.
Figure 1: Figure 2b: Figure 3: The device has three arms that are gathered in a handgrip with programmable buttons.
The position and the forces rendered by each arm are updated times per second to create a real life experience for the user. Having developed a set of prototypes since , Carnegie Mellon University proposed in March an innovative haptic device based on magnets. The device figure 5 , built into a bowl-shaped cavity in a desk, includes a levitating bar that, grasped by the user, makes the magnets exert force on the bar. Missing the mechanical linkages, the system responds instantly due to no latencies from mechanical force- feedback.
The perception of very smooth movements of the bar up to microns permits the feel of differences between textures and subtle effects of friction. The disadvantage of the system is the limited range of motion for the joystick: Figure 4: Novint Falcon Figure 5: Magnetic levitation maglev The following characteristics, also known as performance measures, are common to all haptic devices Wall, Unlike continuous force, maximum force needs to be exerted only over a short period of time e.
Latency includes computation by the computer and therefore depends on the speed of the computer as well as the speed of the device. This should be as low as possible to minimize the impact of the device controller on rendered forces.
SensAble OpenHaptics Toolkit www. Reachin API www.
The API provides a base of pre-written code that allows for easy and rapid development of applications that target specific needs of the user.
UK Haptics, a newly established medical software development company, agreed to use Reachin API as the core haptic technology platform for their Virtual Veins application. Virtual Veins is a medical simulation package for training medical staff in catheter insertion. The Immersion API www.
It provides the code necessary for developers to design and incorporate haptic effects into their applications. Leading auto manufacturer, BMW, has licensed Immersion's TouchSense technology to create the automotive industry's first intuitive information and control system called iDrive. The iDrive features a single control dial mounted on the central console, which allows a driver to have instant and total control of every comfort element in the car through their sense of touch.
H3D API is designed mainly for users who want to develop haptics applications from scratch, rather than for those who want to add haptics to existing applications.

It allows users to focus their work on the behavior of the application and ignore the issues of haptics geometry rendering as well as synchronization of graphics and haptics.
The API is also extended with scripting capabilities, allowing the user to perform rapid prototyping using the Python scripting language.
Effectiveness of Simulation and Training With Haptic Feedback In a study Moody et al Moody, demonstrated the effect of a force feedback system in the training and assessment of surgeons. After the task was demonstrated and explained to each subject by the experimenter, each of the 20 participants performed two test sutures to familiarise themselves with the task and the experimental setting.No notes for slide.
Opportunities and Limitations of Haptic Technologies for Non-visual Access to 2D and 3D Graphics
Haptic Rendering: It is a process of applying forces to the user through a force-feedback device. In this course we will a compelling sense of tactile "realness.
These devices mainly consist of robotic manipulators that push back against a user with the forces that correspond to the environment that the virtual effector's is in.
These motors haptics in computer interface design goes beyond using need to operate at resonance and also have limited range of touch to simulate forces found in nature.
