In a groundbreaking initiative, researcher Danqing Liu has secured €939,619 from the NWO Open Technology Programme (OTP) to advance haptic technology—specifically, enhancing human-machine interactions through the sense of touch. This project, titled Harmonizing Haptics: Liquid Crystal-Enhanced Human-Machine Interactions, aims to develop wearable devices that deliver tactile feedback using liquid-crystal polymers.
The primary goal is to assist blind and visually impaired individuals in navigating daily life more effectively. Liu's work involves collaboration with Ghislaine Vantomme, forming an interdisciplinary team within the Chemical Engineering and Chemistry department to push the boundaries of this innovative technology.
While modern technology often relies heavily on visual interfaces, Liu emphasizes the importance of touch, noting that the transition from physical controls to virtual screens has led to user dissatisfaction and even emotional distress. The proposed wearables, which can take the form of rings, bracelets, or necklaces, aim to restore intuitive interaction through tactile sensations.
These devices will leverage liquid crystal polymers, which possess unique properties that allow them to change shape in response to stimuli such as heat or electric current. For example, a wearable could provide a gentle tap when a cup is nearly full or alert the user to nearby obstacles.
Initially, Liu's research will focus on creating a prototype designed specifically for the visually impaired, with applications aimed at aiding navigation in complex environments like busy streets. 'With the support of the OTP grant, we will recruit PhDs and postdoctoral researchers to advance the development of innovative materials and create a functional demonstrator,' Liu stated.
Haptics, the science of touch, encompasses how humans perceive information through tactile stimuli, including textures, shapes, and movements. While touchscreens have made technology more accessible, they often lack the direct feedback that physical buttons provide. Liu's research group is dedicated to enhancing human interaction with technology through advanced materials, while Vantomme's group specializes in organic synthesis and molecular assembly.
'I am very excited by this grant, as it will strengthen our collaboration,' Vantomme remarked. 'Our groups bridge the gap between molecules and devices, and by combining our expertise, we can push the boundaries of applied scientific research further.'
The NWO Open Technology Programme funds applied research that transcends disciplinary boundaries, fostering collaborations with significant scientific and social impact. Liu's project represents a step forward in creating technology that not only connects but also empowers individuals with visual impairments.
