Learning and performance with gesture guides

Fraser Anderson, Walter F. Bischof
2013 Proceedings of the SIGCHI Conference on Human Factors in Computing Systems - CHI '13  
Next, we present two studies that help us better understand the role of visual feedback, finding that it has a dramatic effect on the degree to which gestures are learned.  ...  After decades of research, gestural interfaces are becoming increasingly commonplace in our interactions with modern devices.  ...  With these keyboards, users draw strokes directly over top of the desired letters to input text on touchscreen devices.  ...

Unmediated Interaction: Communicating with Computers and Embedded Devices as If They Are Not There

Brian Anthony Smith
Third, I introduce computationally optimized keyboard designs for touchscreen manual input that allow people to type on smartphones faster and with far fewer errors than currently possible.  ...  Last, I introduce the racing auditory display (RAD), an audio system that makes it possible for people who are blind to play the same types of racing games that sighted players can play, and with a similar  ...  The touchscreen keyboard optimized for gesture typing builds on existing stroke-based virtual keyboards (Section 2.6) and keyboard layout optimization work (Section 2.7).  ...

A Device-Independent Interaction Framework Towards the Implementation of Reduced Crew Operations

Millie Sterling
The results of this work were then applied to the construction of a mobile flight deck simulator to demonstrate the author's vision for reduced crew flight deck operations with multimodal interaction.  ...  The simulator depicts six realistic scenarios of a reduced crew flight with investigated interaction techniques.  ...  Input is any information about a physical environment that a machine can sense (e.g. movement of a mouse, stroke of a key on a keyboard, changes of light across a light sensor, sound waves into a microphone  ...
