Error related negativity in observing interactive tasks

Abstract

Error Related Negativity is triggered when a user either makes a mistake or the application behaves differently from their expectation. It can also appear while observing another user making a mistake. This paper investigates ERN in collaborative settings where observing another user (the executer) perform a task is typical and then explores its applicability to HCI. We first show that ERN can be detected on signals captured by commodity EEG headsets like an Emotiv headset when observing another person perform a typical multiple-choice reaction time task. We then investigate the anticipation effects by detecting ERN in the time interval when an executer is reaching towards an answer. We show that we can detect this signal with both a clinical EEG device and with an Emotiv headset. Our results show that online single trial detection is possible using both headsets during tasks that are typical of collaborative interactive applications. However there is a trade-off between the detection speed and the quality/prices of the headsets. Based on the results, we discuss and present several HCI scenarios for use of ERN in observing tasks and collaborative settings.

Iteratively Adapting Avatars using Task-Integrated Optimisation

“…Physiological data may also be used to infer non-movement properties of the body. Electroencephalographic estimations of emotional state [5] or error related negativity [33] are also examples of features which the optimiser could be directed by.…”

EEG-based Evaluation of Cognitive Workload Induced by Acoustic Parameters for Data Sonification

“…Several previous works have investigated Event Related Potentials (ERPs) for human-centric decision tasks like emotion recognition [4], image annotation [17] and error identification [25]. These markers act as a bridge between neuroscience and behavioral studies, facilitating better understanding of the structural and functional relevance of neural activity to the task on hand, and validation of the EEG data.…”

Detecting Swipe Errors on Touchscreens using Grip Modulation

“…have used off-the-shelf EEG headset to detect error-related negativity (ErrN) when a user makes a mistake [28]. Using a similar headset, the ErrN signals present when observing someone else making a mistake are described in [29].…”

“…Besides BCI spelling applications, ErrN also has been used to detect errors in diverse interactive tasks [28] [29]. These studies used a commercially available EEG headset to capture ErrN signals triggered from Flanker, button selection and pointing tasks.…”
