An experimental study of speech/gesture interactions and distance encoding
Speech Communication (SPCO), Volume 55, Issue 4Pages 553–571https://doi.org/10.1016/j.specom.2012.11.003This paper explores the possible encoding of distance information in vocal and manual pointing and its relationship with the linguistic structure of deictic words, as well as speech/gesture cooperation within the process of deixis. Two experiments ...

Navigation by pointing to GPS locations
Personal and Ubiquitous Computing (PUC), Volume 16, Issue 8Pages 959–971https://doi.org/10.1007/s00779-011-0456-3This article deals with a method for interacting with a handheld navigation application, based on using the mobile device for pointing. When the user points the device in any direction, feedback will be provided based on if the user is aiming at the ...

Reaching the same point: Effects on consistency when pointing at objects in the physical environment without feedback
International Journal of Human-Computer Studies (IJHC), Volume 69, Issue 1-2Pages 9–18https://doi.org/10.1016/j.ijhcs.2010.10.003We present results from a study examining the impact of several human and technical factors on selection by pointing a handheld pointer at physical objects in a room without feedback. A basic mobile sensor assembly is used to demonstrate the feasibility ...

The Vibe: a versatile vision-to-audition sensory substitution device
We describe a sensory substitution scheme that converts a video stream into an audio stream in real-time. It was initially developed as a research tool for studying human ability to learn new ways of perceiving the world: the Vibe can give us the ...

A two visual systems approach to understanding voice and gestural interaction
Virtual Reality (VIRT), Volume 8, Issue 4Pages 231–241It is important to consider the physiological and behavioral mechanisms that allow users to physically interact with virtual environments. Inspired by a neuroanatomical model of perception and action known as the two visual systems hypothesis, we ...

Speed-accuracy tradeoff in Fitts' law tasks: on the equivalency of actual and nominal pointing precision
International Journal of Human-Computer Studies (IJHC), Volume 61, Issue 6Pages 823–856https://doi.org/10.1016/j.ijhcs.2004.09.007Pointing tasks in human-computer interaction obey certain speed-accuracy tradeoff rules. In general, the more accurate the task to be accomplished, the longer it takes and vice versa. Fitts' law models the speed-accuracy tradeoff effect in pointing as ...
