Haptic-audio interfaces allow haptic exploration of statistical line graphs accompanied by sound or speech, thus providing access to exploration by visually impaired people. Verbally assisted haptic graph exploration can be seen as a task-oriented collaborative activity between two partners, a haptic explorer and an observing assistant, who are disposed to individual preferences for using reference frames. The experimental findings reveal that haptic explorers' spatial reference frames are mostly induced by hand movements, leading to action perspective instead of conventionally left-to-right spatiotemporal perspective. Moreover, the communicational goal may result in a switch in perspective.

Switching reference-frame preferences during verbally assisted haptic-graph comprehension Alacam, Ozge; Christopher, Habel; Cengiz, Acarturk (2015-09-01) Haptic–audio interfaces allow haptic exploration of statistical line graphs accompanied by sound or speech, thus providing access to exploration by visually impaired people. Verbally assisted haptic graph exploration can be seen as a task-oriented collaborative activity between two partners, a haptic explorer and an observing assistant, who are disposed to individual preferences for using reference frames.

Haptic exploration patterns in virtual line graph comprehension DENİZ, OZAN; MEHMETCAN, FAL; Acartürk, Cengiz (2015-08-07) Multi-modal interfaces that provide haptic access to statistical line graphs combined with verbal assistance are proposed as an effective tool to fulfill the needs of visually impaired people. Graphs do not only present data, they also provide and elicit the extraction of second order entities (such as maxima or trends), which are closely linked to shape properties of the graphs. In an experimental study, we investigated collaborative joint activities between haptic explorers of graphs and verbal assistants...
Investigation of haptic line graph comprehension through co production of gesture and language Deniz, Ozan; Mehmetcan, Fal; Acartürk, Cengiz (null; 2013-06-30) In communication settings, statistical graphs accompany language by providing visual access to various aspects of domain entities, such as conveying information about trends. A similar and comparable means for providing perceptual access is to provide haptic graphs for blind people. In this study, we present the results of an experimental study that aimed to investigate visual line graphs and haptic line graphs in time domain by means of gesture production as an indicator of event conceptualization. The par...
Gestures in communication through line graphs Özge, Alaçam; Christopher, Habel; Acartürk, Cengiz (null; 2012-08-31) Line graphs are widely used in communication settings, for conveying information about states and processes that unfold in time. The communication is achieved by the contribution of other modalities than graphs, such as language and gestures. In a set of experimental investigations, we analyzed the production and comprehension of gestures during communication through line graphs. The findings reveal a systematic use of gestures as well as the limitations of cognitive resources due to the split of attention ...
Deep Hierarchies in the Primate Visual Cortex: What Can We Learn for Computer Vision? KRÜGER, Norbert; JANSSEN, Peter; Kalkan, Sinan; LAPPE, Markus; LEONARDİS, Ales; PİATER, Justus; Rodriguez-Sanchez, Antonio J.; WİSKOTT, Laurenz (Institute of Electrical and Electronics Engineers (IEEE), 2013-08-01) Computational modeling of the primate visual system yields insights of potential relevance to some of the challenges that computer vision is facing, such as object recognition and categorization, motion detection and activity recognition, or vision-based navigation and manipulation. This paper reviews some functional principles and structures that are generally thought to underlie the primate visual cortex, and attempts to extract biological principles that could further advance computer vision research.
