“…Consequently, this may have had an undesired effect on targeting performance when carrying the different types of objects since the indoor environment is much calmer than a real world setting therefore making the context less challenging for the user. However, Lin et al [7] suggested using an artificial route with obstacles to increase the user's cognitive workload to a level similar to walking in outdoor settings.…”

Abstract. This paper investigates the effects of encumbrance (holding different types of objects while using mobile devices) to understand the interaction difficulties that it causes. An experiment was conducted where participants performed a target acquisition task on a touchscreen mobile phone while carrying different types of bags and boxes. Mobility was also evaluated since people carry items from one place to another. Motion capture hardware was used to track hand and arm postures to examine how holding the different types of objects caused excessive movement and instability therefore resulting in performance to decline. The results showed encumbrance and mobility caused target accuracy to decrease although input while holding the box under the non-dominant arm was more accurate and exerted quicker targeting times than holding no objects. Encumbrance affected the dominant hand more than the non-dominant hand as targeting error significantly increased and caused greater hand instability. The issues caused by encumbrance suggest the topic requires more attention from researchers and users would benefit greatly if better interaction techniques and applications are developed to counteract the problems.

“…Research has been conducted on, for example, the impact that various mobility situations have on stylus-based tapping performance in PDAs (Lin et al 2007); on the effects that changes in motion, lighting and task type have on mobile-device users' performance and workload (Barnard et al 2007); and on the relationship between walking speed and text-input performance (Mizobuchi et al 2005). In particular, scholars have shown that walking affects interaction with mobile devices and have proposed systems for improving text entry on touchscreens while users are walking (e.g.…”

Mobile devices have been used for at least 5 years in the oil and gas industry. The interaction-design challenge is to develop a holistic view of operator-device interaction in hazardous areas to ensure that this mobile technology best serves the goals of both its end users and the oil and gas organizations. Introducing mobile devices can change the environment, the workers and even the industry's objectives. In this paper, we provided insights into work practices and mobile-device use at two Norwegian natural-gas processing plants. Using methods inspired by ethnographic and interaction-design research, we investigated how operators used their mobile equipment in the field, and we explored the extent to which mobile-device use improved procedures and satisfied users' needs. In contrast to many other studies on mobile-device use, this study drew upon empirical observations of real operations in hazardous environments.

“…The focus of many studies has been on SIID as a singular concept, and designing technology that improves performance by attempting to diminish the effects of SIID (Zhu, Ma, Feng, & Sears, 2009), (Lin, Goldman, Price, Sears, & Jacko, 2007;Goel, Findlater, & Wobbrock, 2012). Examples include Lin, et al, who showed that, while attempting data input onto a PDA with a stylus and walking through an obstacle course, participants reduced their walking speed by 36% and increased their error rate compared to walking on a treadmill (Lin, Goldman, Price, Sears, & Jacko, 2007).…”

Understanding Severely Constraining Situational Impairments When Accessing Mobile Technologies

My research aims to investigate ways to support mobile users facing "severely constraining situational impairments" (SCSI) where multiple channels of communication are restricted, overloaded or unavailable. An empirical study will initially be undertaken to identify the range of limitations faced by mobile device users when facing unpredictable situations (e.g. when receiving a text message while concentrating on the road when driving). Based on the findings, a second study will be developed to map feasible forms of technology to the impairments faced. A final study will then be conducted to evaluate the efficacy of the mappings, with the ultimate goal of producing a set of guidelines that will inform interface designers when developing tools to support individuals who are facing severely constraining situational impairments. The outcomes of this research will hopefully inform design of mobile technology in addressing SCSIs. Situational Impairments. SIID. Mobile HCI. Interface Modalities
