“…Because I am taking… I took a three‐panel solar charger last year [P02].” P02 moves on to highlight an instance of power loss when one of his team “went two days without power at all. Mainly because he thought he'd switched his, one of his devices off, and he hadn't.” Our survey reveals that 78.4% of 2019 TGO participants carried a power bank, reflecting the power management concerns highlighted by Dhir et al (2012) and Rahmati et al (2007).…”

“…Rahmati, Qian, and Zhong (2007) found that 80% of mobile phone users take measures to increase battery lifetime and that a perception of the need to maximize battery life is a source of anxiety. Dhir, Kaur, Jere, and Albidewi (2012) investigated perceptions towards battery life via a series of focus groups and found evidence of similar battery life anxiety, with several participants experiencing significant frustration at running out of battery.…”

The popular outdoor pursuit of backpacking is profoundly changing as the community embraces contemporary information technologies. However, there is little empirical evidence on the adoption and use of consumer electronics by backpackers, nor the implications this has for their habits, practices, and interactions. We investigate long‐distance backpackers' articulations with mobile information technology during the TGO Challenge, a coast‐to‐coast crossing of the Scottish Highlands. By employing mixed methods, we explore how and why backpackers use such technology when planning and undertaking their journeys via a survey (n = 116), pre‐ and post‐challenge interviews with selected TGO participants, and daily in‐field video‐logs. Our results suggest many advantages to using technology in this context, including fluidity of communications and access, while noting that reliance on technology is leading to issues such as increased need for battery power management, and deskilling. The findings highlight implications for the juxtaposition between outdoor recreation, information behavior, and human computer interaction (HCI) and suggest future work in this area.

“…when mobile device's power demand and our dependence on them became arguably bigger), Ferreira et al [13] found that, from 12 smartphone participants, all experienced a period of time where the device was without power, and most displayed opportunistic charging behaviours [12]. Dhir et al [10] report similar battery life anxiety from a series of focus groups of 27 users in Alice, South Africa, with several participants experiencing significant frustration at running out of battery on their mobile phone and carrying around phone chargers to avoid this situation.…”

Current devices have limited battery life, typically lasting less than one day. This can lead to situations where critical tasks, such as making an emergency phone call, are not possible. Other devices, supporting different functionality, may have sufficient battery life to enable this task. We present PowerShake; an exploration of power as a shareable commodity between mobile (and wearable) devices. PowerShake enables users to control the balance of power levels in their own devices (intra-personal transactions) and to trade power with others (inter-personal transactions) according to their ongoing usage requirements. This paper demonstrates Wireless Power Transfer (WPT) between mobile devices. PowerShake is: simple to perform on-the-go; supports ongoing/continuous tasks (transferring at ~3.1W); fits in a small form factor; and is compliant with electromagnetic safety guidelines while providing charging efficiency similar to other standards (48.2% vs. 51.2% in Qi). Based on our proposed technical implementation, we run a series of workshops to derive candidate designs for PowerShake enabled devices and interactions, and to bring to light the social implications of power as a tradable asset.

“…Findings from the authors' prior fieldwork in rural Kenya revealed that charging handset batteries was a major problem for villagers [24,34], a dilemma populations in India, China, and South Africa also face [11]. The time and money required to "preserve the charge" then inhibited participants' mobile phone use by limiting how long they kept the device turned on and how long they spoke.…”

Can human-powered devices solve the electricity gap for the millions of rural Africans adopting mobile phones? Findings from our long-term evaluation of two personal crank-based charging systems in Kenya reveal that small hand and leg-powered devices do have potential to meet the needs of rural mobile phone users. Unfortunately, device breakage, theft and incompatibility with handsets, coupled with lack of consumer credit and poorly functioning markets for these goods mean these represent only a partial solution to the mobile phone charging problem. Drawing from our fieldwork, we motivate a HCI4D/ICTD design and evaluation agenda that better accounts for unique individuals' geographic, financial, and economic circumstances or their "human computer ecosystem". Key strategies for implementing this agenda are engaging with diverse users on their own terms and conducting long-term qualitative evaluations to reveal how acceptance and usability change over time.
