ShearTouch - Towards a wearable tactile feedback device to provide continuous shear force sensation in real time (2020)
Presentation / Conference Contribution

Force feedback in current teleoperation systems typically only provides haptic/kinaesthetic feedback to operators in the form of normal forces. However, it is proposed in this paper that the introduction of shear (or lateral) force feedback to operat...

Towards establishing a 'cooperation' measure for coupled movement in close-proximity human-robot interaction (2020)
Presentation / Conference Contribution

To achieve safe close-proximity human-robot interaction , particularly for physically assitive tasks, robot motion planning needs to recognize and adapt to the behaviour of humans in the long-term. Generally, motion prediction with probabilistic conf... Read More about Towards establishing a 'cooperation' measure for coupled movement in close-proximity human-robot interaction.

The impact of affective verbal expressions in social robots (2020)
Presentation / Conference Contribution

This research investigates whether there is an ethical concern in robots misrepresenting their internal state through speech. Participants were asked to discuss their food preferences with a robot, where the robot would either respond through facts o...

The need for ethical principles and guidelines in social robots (2019)
Presentation / Conference Contribution

This paper stresses the importance of establishing ethical principles regarding possible (psychological) effects of interactions with (social) robots. It highlights existing principles and standards regarding artificial intelligence systems and robot... Read More about The need for ethical principles and guidelines in social robots.

Real-time electromagnetic tracking of orthopaedic pins for robot-assisted fracture surgery (2018)
Presentation / Conference Contribution

Tracking devices are an essential component in image guided surgery particularly when precise treatment or implant positioning are required. In this paper we explore the use of an electromagnetic tracking device (Polaris Aurora, NDI Inc.) as an alter...

Ethical considerations of (contextually) affective robot behaviour (2018)
Presentation / Conference Contribution

The use of social robots can bring many benefits, but raises ethical concerns as well. One of these concerns, emotional deception, was investigated in this research. First, affective robot behaviour is validated, followed by a user study to investiga... Read More about Ethical considerations of (contextually) affective robot behaviour.

Upper limb motion intent recognition using tactile sensing (2017)
Presentation / Conference Contribution

Focusing on upper limb rehabilitation of weak stroke patients, this pilot study explores how motion intent can be detected using force sensitive resistors (FSR). This is part of a bigger project which will see the actuation and control of an intent-d... Read More about Upper limb motion intent recognition using tactile sensing.

What's up?-Resolving interaction ambiguity through non-visual cues for a robotic dressing assistant (2017)
Presentation / Conference Contribution

© 2017 IEEE. Robots that can assist in activities of daily living (ADL) such as dressing assistance, need to be capable of intuitive and safe interaction. Vision systems are often used to provide information on the position and movement of the robot...

An assistive robot to support dressing-strategies for planning and error handling (2016)
Presentation / Conference Contribution

© 2016 IEEE. Assistive robots are emerging to address a social need due to changing demographic trends such as an ageing population. The main emphasis is to offer independence to those in need and to fill a potential labour gap in response to the inc...
