Having looked into how the connectivity of mobile devices can be useful in providing flexible and diverse communication channels for those carrying out charity work, the following part of this article highlights the more interactive features that increase the functionality of the devices for both aid workers and disadvantaged individuals.
Cameras
A digital camera is now standard in the vast majority of portable or mobile devices and an increasing proportion can capture both photo and video. Coupled with the aforementioned connectivity of such devices, this provides many charity or health organisations with the ability to capture evidence and information on what is happening ‘in the field’ and share it almost immediately with their target audiences. For example, the visual aspects of symptoms can be recorded and reported by health professionals to their colleagues for further analysis; or evidence on the extent of disasters can be collated, shared and assessed to inform what actions should be taken next. Moreover, this evidence can be shared with the wider world to effectively communicate situations where aid action is required to the public, across the globe, in order to raise the profile and ultimately the funding for a cause. Even where charity or aid workers are not on the scene, the prevalence of portable devices with in-built cameras and connectivity means that the public’s attention can be drawn to those in need by witnesses with such devices documenting events.
Size
Arguably the second decisive factor in defining a device as portable is its size. Devices such as tablets and particularly smartphones can be carried and transported to any part of the world that people can get themselves to. As these devices are packed with computing power that would have, only a few years previously, been restricted to desktop PCs, plus connectivity that crosses boundaries, they are not only able to collect information but process it, analyse it, share it and report it wherever they are. Whether it’s individuals who require more assistance themselves, or people and organisations helping others, the fact that they are not tethered to a location means that they are able to deal with demands when and where they occur.
Touch Screen Displays
The development of a touch screen is fundamental to the existence of portable devices as it has allowed them to do away with both physical keyboards and mice to become handheld and pocket sized.
What’s more, however, touch screens provide a more intuitive way for some less able users to make the most out of their device. By generating possibilities around the creation of specific accessibility applications, they open up functionality to individuals with specific needs. Large, increasingly high resolution displays, for example, allow touch screen controls to be made as large as possible and well defined for those who have difficulties perceiving the usual small controls. Using software (see below), controls no longer need to be fixed and can be dynamically configured to suit the user’s needs. Button colours, keyboard layouts and languages, for example, can all be changed using software to benefit the device’s user.
Software
Finally the element that brings many of the hardware capabilities together, integrates them and leads to ingenious solutions to niche but demanding problems is the software. On each platform, solid and useful pre-packaged software is complemented by stores of 3rd party applications, developed by people ranging from global software companies to keen individuals building apps in their spare time. It is hard to find a problem too big or too small where someone hasn’t attempted to develop an app to deal with it. Therefore with mobile device processing power growing at an exponential rate and the physical capabilities of high connectivity, GPS and camera functions all on offer, the real potential mobile devices have in aiding good causes is the creativity of those developing solutions for them.
