The paper I chose was Scott Hudson\u2019s paper \u201cWhack Gestures: Inexact and Inattentive Interaction with Mobile Devices\u201d (2011). It introduced the concept of \u201cwhack gestures\u201d as a new form of interaction with mobile devices. Rather than relying on more precise and deliberate touch inputs, whack gestures allowed for a means of interaction that require only minimal user attention. This approach is intended for situations where users need to interact quickly and with little focus. An example of such usage was quickly responding to (e.g. silencing) a ringing phone.<\/p>\n\n\n\n
Hudson discusses the development and use of interfaces that accommodate these inexact gestures. He emphasizes the importance of building systems that can recognize and respond to uncertain or incomplete user input while maintaining accuracy. User testing of the effectiveness of their implementation demonstrated that it is possible to design a system that achieves both high accuracy and low false positive rates. <\/p>\n\n\n\n
Both in this paper and in Hudson\u2019s talk \u201cThe Future is Not What it Used to Be,\u201d the concepts of uncertainty and ubiquitous computing are important considerations for future human-computer interactions. In his talk, Hudson discussed the uncertainty involved in natural interaction with gesture, speech etc. and using recognizers to decipher inputs. He then described Julia Schwarz\u2019s approach to addressing the uncertainty with Monte Carlo probability representations and a particle filtering approach. He also proposed the possibility of zero (or negative) latency interfaces that arise when interactions are handled in this way. Ultimately, both the paper and the talk reflect technology adapting to human behavior despite how inexact and inattentive the behavior might be.<\/p>\n\n\n\n
