Deep Learning-based Haptic Guidance

2020 - present

Haptic guidance (HG) improves users’ task performance through physical interaction between robots and users. We presented two types of HG: optimal action-based HG (OAHG), which assists users with an optimal action, and user prediction-based HG (UPHG), which assists users with their next predicted action. Deep learning-based approaches were applied, including a self-play-based reinforcement learning framework for OAHG and a meta-learning framework for UPHG. Through a user study, we validated the assisting performance of each HG for users conducting a haptic task and investigated how the user’s subjective evaluation difers for each HG.

Imaginary Rollout-based Robotic Guide Training

2017 - 2019

Training a robot that engages with people is challenging, because it is expensive to involve people in a robot training process requiring numerous data samples. We proposed a deep learning-based model that predict human path following a robot and an evolution strategy-baesd robot training method using "imaginary rollouts" generated by the human predictive model, which compensates for this sample inefficiency problem. We applied the proposed method to the training of a robotic guide for visually impaired people, which was designed to collect multimodal human response data and reflect such data when selecting the robot’s actions.

Study on the Effect of Haptic Information in Multitasking Process

2015 - 2016

We implemented a multimodal task interruption environment involving the simultaneous presentation of visual information and haptic stimuli in order to investigate how the combined stimuli affect the performance on the primary task (i.e., cost of interruption). A user test (n=21) indicated that, within a visuo-tactile task environment, redundant haptic information may not only increase accuracy on the primary task but also reduce the cost of interruption in terms of accuracy.
