The idea here is simple, I'm writing a near-future story and want to accurately represent how technology will progress. I'm looking at the current smart phone and want to expand its use to represent the realistic future. I'm looking for a general idea as to how the devices will be used, with a particular look at how they will interact with each other; i.e. how person A and person B may use their smart-devices to trade information and communicate even when standing in close proximity.
Presume a few basic things:
This is set in the near future, a generation or so. I want to stay true to the non-centralized/non-regulated nature of internet of today. Many things in this future integrate together by now, but only because people came to adopt standards that they agreed were worth using. Interactions that require a monopoly to dictate all decisions about interoperability to be created won't be common.
reliable high speed wireless internet is now considered a universal utility and is provided free by governments.
smart devices are cheaper and battery life is quite long. Generally it's safe to assume almost everyone is going to have a working device on them.
Many third party tools can be connected to with your device and this is the most common way to interact with them. You pay for something at the store using your device, you instruct your smart car where to drive with your device, You make reservations at a restaurant with your device and it buzzes when your seat is ready etc.
devices allow lots of customization that a more tech-savy generation uses semi often, one of the reason other things interface with your device by default is so they can check what your preferences are. Everything uses your preferred language, knows rather to use metric or English units and preferred currency etc. by querying your device when you walk up to it. Every gas station can tell what quality of gas your want if you set it on your device etc.
for now assume the device deactivates or switches to some restricted mode if someone other then its owner uses it and generally hacking and use of stolen devices is not much more of a threat then today. Also no government is monitoring people through their device, I'll tackle these issues later.
The devices are sill small enough to fit on your person, which limits how we can interact with them. If your using a computer for awhile you still sit in front of a monitor and keyboard. I'm probably going to have everyone have a cloud based VM so rather then having a laptop you have a docking station at home, work, etc. that can connect to 'your' computer.
Given this I'm trying to accurately depict how people will be using these devices to feel realistic to new technology rather then just putting a shiny coating onto or existing capability. For that I'm looking for anything I may fail to realize about the use and function the devices will have, and how their daily use will look. What other features will be integrated into them? what other sensors might they have to support additional functionality? Will we blur the lines between personal computer, cloud, and smart device? How will the constant communication between personal device and other tools/tech, as well as two people sending data back and forth on their devices, be done in a quicker and convenient manner?
