Gestures within Human-Technology Choreographies for Interaction Design
In the traditional use-oriented approach, only a fraction of gestures are taken as relevant to interaction. In this paper we argue that gestures should not be handled only as isolated objects of application use, but they should rather be understood as dynamic moments of embodied presence belonging to an experiential chain of different movements which has its own significance as a whole. In the current study, we call the embodied, experiential continuum of human action choreography. We assume that choreography is a fruitful theoretical concept in understanding interaction design because by choreography we can understand gestures as building up a chain of a bigger whole. The dynamic formulati…
Designing Gesture-Based Control for Factory Automation
We report the development and evaluation of a gesture-based interaction prototype for controlling the loading station of a factory automation system. In this context, gesture-based interaction has the potential to free users from the tedious physical controls but it must also account for safety considerations and users’ perceptions. We evaluated the gesture interaction concept in the field to understand its applicability to industrial settings. Our findings suggest that gesture-based interaction is an emotional, physically charged experience that has the potential to enhance the work process. Participants’ feedback also highlighted challenges related to the reliability of gesture recognitio…
Applying Finite State Process Algebra to Formally Specify a Computational Model of Security Requirements in the Key2phone-Mobile Access Solution
Key2phone is a mobile access solution which turns mobile phone into a key for electronic locks, doors and gates. In this paper, we elicit and analyse the essential and necessary safety and security requirements that need to be considered for the Key2phone interaction system. The paper elaborates on suggestions/solutions for the realisation of safety and security concerns considering the Internet of Things (IoT) infrastructure. The authors structure these requirements and illustrate particular computational solutions by deploying the Labelled Transition System Analyser (LTSA), a modelling tool that supports a process algebra notation called Finite State Process (FSP). While determining an in…
