User Error: Resisting Computer Culture

Resisting the tick box culture: refocusing medical education and training.

Resisting variables – service user/survivor perspectives on researching coercion

Coercion in psychiatry and the fight against forced treatment are two of the main topics in the mental health service user/psychiatric survivor movement worldwide. At the same time, our own user-led or survivor-controlled research in this field is almost nonexistent. This chapter explores some of the structural obstacles to including service user/survivor perspectives in psychiatric research on...

Resisting Tag Spam by Leveraging Implicit User Behaviors

Tagging systems are vulnerable to tag spam attacks. However, defending against tag spam has been challenging in practice, since adversaries can easily launch spam attacks in various ways and scales. To deeply understand users’ tagging behaviors and explore more effective defense, this paper first conducts measurement experiments on public datasets of two representative tagging systems: Del.icio...

Acoustic Correlates of User Response to Error in Human-computer Dialogues

Using tagged data from the DARPA Communicator Project, we investigate acoustic features of user responses to system errors. We measure acoustic parameters such as energy, fundamental frequency, sub-band energy, ratios of voiced, unvoiced and silent regions of speech, fundamental frequency slope, spectral slope, and spectral center of gravity. We investigate different types of user responses to ...

An Experimental Method Study of User Error Classification in Human-computer Interface

In the paper, we proposed an experimental analysis model of user error and established the error-cognition corresponding relationship according to the error collection-classification method. Through the design of error experiment, various errors in operation interface as well as reasonable and sufficient data were obtained. Based on the repeated experiments and user interviews, we classified er...
