“…Using haptic technology in this context is especially valuable because it allows the feeling of touch and pressure to be recreated, so doctors or surgeons can realistically feel how a procedure would work. Haptic technology is also used in medicine in modern prosthetics that allow patients to "feel" different surfaces and shapes in a similar way to using a real limb; this naturally increases the usability of the prosthesis for the patient and allows precise activities that require a sense of pressure, surface or texture to be performed (Fortin et al, 2014). Haptic technology is also used as a simulation tool in military scenarios, particularly to increase the safety of soldiers in simulations of different activities that are difficult to perform in natural conditions (Meshram and Sahu, 2014).…”

Purpose The subject of the paper is haptic technology considered as a tool for improving the performance of libraries. The purpose of this paper is to determine the potential of this technology in the design of innovative library services. Specific goals include description of the ideas and features of haptic technology, identification of the main areas of application of haptic technology and outlining the possible uses of haptic technology in library services. Design/methodology/approach The method of analysis and criticism of literature was used. The state of research from the period 2008–2018 on the use of haptic technology in libraries was established based on a systematic search of selected sources, such as resources indexed by Google Scholar, the Worldcat catalogue and the LISTA database. Findings Haptic technology is a topic that should be covered more often in library and information science because it has a great potential to improve library services and make them more attractive. The two most important areas in which haptic technology could be applied in libraries are education and services, especially for disabled users that have special educational and service needs. Although it could be very helpful for disabled users, haptic technology can also be used in various contexts to provide more responsive and intuitive user interfaces for electronic library services. Research limitations/implications The purpose of this paper is not to exhaust the topic but to continue and complement the problems pointed out by P. Fernandez and to initiate further discussion on this topic. Practical implications The results can be widely used in practice as a framework for the implementation of haptic technology in libraries. Social implications The paper can help to facilitate the debate on the role of implementing new technologies in libraries. Originality/value The problem of haptic technology is very rarely addressed in the subject literature in the field of library and information science.

This paper presents a vibrotactile haptic feedback system for use under dynamic conditions, verifies its functionality, and shows how results may be affected by the amount of training that subjects receive. We hope that by using vibrotactile feedback to distinguish between different textures, upper-limb amputees may be able to partially regain the sense of touch. During a previous experiment (Motamedi et al., 2015) we noticed a correlation between how familiar the subjects were with haptic systems, and how well they were able to use the haptic system to accurately identify textures. This observation lead us to conduct a second experiment, the results of which are the main focus of this paper. We began with a group of subjects who were completely unfamiliar with haptic systems, and tracked the improvements in their accuracy over a period of four weeks. Although the subjects showed a 16% improvement in their ability to recognize textures, going from a 64% success rate after the first week to 80% after the fourth, perfect accuracy was not attained. A subsequent experiment, however, shows that this result should not diminish our perception of the haptic system's effectiveness. When we asked the same subjects to identify the textures using only their fingertips, we found that even humans cannot distinguish between near-identical textures with complete accuracy. The subjects' overall success rate when using their own hands was 91%, demonstrating that the proposed haptic system is not far from achieving the same texture recognition capabilities as the human sense of touch.
