TLDR
A modular solution to mobile usability labs is presented, allowing both belt- and backpack-worn configurations and flexible division of equipment between the user, the moderator, and the environment, without sacrificing data quality, operational duration, or light weight.Abstract:
The main challenges for mobile usability labs, as measurement instruments, lay not so much on being able to record what happens on the user interface, but capturing the interactional relationship between the user and the environment. An ideal mobile usability lab would enable recording, with sufficient accuracy and reliability, the user's deployment of gaze, the hands, the near bodyspace, proximate and distant objects of interest, as well as abrupt environmental events. An inherent complication is that the equipment will affect these events and is affected by them. We argue that a balance between coverage and obtrusiveness must be found on a per case basis.
We present a modular solution to mobile usability labs, allowing both belt- and backpack-worn configurations and flexible division of equipment between the user, the moderator, and the environment. These benefits were achieved without sacrificing data quality, operational duration, or light weight. We describe system design rationale and report first experiences from a field experiment. Current work concentrates on simplifying the system to improve cost-efficiency.read more

Was it worth the hassle?: ten years of mobile HCI research discussions on lab and field evaluations
Jesper Kjeldskov,Mikael B. Skov +1 more
TL;DR: It is suggested that the real question is not if -- but when and how -- to go into the field, and to engage with field studies that are truly in-the-wild, and longitudinal.

A Hybrid Method for Quality Evaluation in the Context of Use for Mobile (3D) Television
TL;DR: A hybrid method is proposed to complement conventional quantitative quality evaluation with concrete tools to identify factors that surround the assessment in the context of use and measure and understand the user-centered quality of experience.

Rethinking Experimental Designs for Field Evaluations
TL;DR: Field studies challenge us to design evaluations as quasi-experiments that don't assume perfect control and randomization, and there are ways to reduce costs.

Mobile Interactions in Context: A Designerly Way Toward Digital Ecology
TL;DR: The design of mobile interactions proposed in this book transcends existing approaches by using the ensemble of form and context as its central unit of analysis and promotes a designerly way of achieving convergence between form and co text through a contextually grounded, wholeness sensitive, and continually unfolding process of design.

Is It Worth the Hassle? Exploring the Added Value of Evaluating the Usability of Context-Aware Mobile Systems in the Field
TL;DR: The results show that the added value of conducting usability evaluations in the field is very little and that recreating central aspects of the use context in a laboratory setting enables the identification of the same usability problem list.

Embodied interaction with a 3D versus 2D mobile map
TL;DR: 2D maps direct users into using reliable and ubiquitous environmental cues like street names and crossings, and 2D better affords the use of pre-knowledge and bodily action to reduce cognitive workload, so some 3D users learned to shift to 2D-like strategies and could thereby improve performance.
