How technologies, design change the need to adopt a particular posture to complete an activity. Simple example? Cameras becoming small enough to use with one hand or even no hands. Binoculars in use below, camera above.
Perhaps more interesting are the emotions associated with a particular posture – the chalet owner scanning the snowline for ice-climbers in Grand Montet – with the sunset only an hour away their window of opportunity to descend was rapidly closing.
