Ways to charge a battery-research

there are mats

and there are ways to charge multiple things at once, WITHOUT physical contact

uses magnetic resonance vs electromagnetic induction, allowing for a more flexible range of transmitted energy

electromagnetic induction – the way some cordless phones work-short range of transmittance, receiver and transmitter MUST be aligned

magnetic resonance – based around a coil, can charge multiple things at once

power-mat, a smaller mat that you can use a USB device to plug into your lap top and charge it. made for phones

-last year Dell came out with a lap top that came with an electromagnetic induction pad –> so it could charge itself without a wire, but it doesn’t seem to be very successful-well known. a challenge in our design is making this technology user friendly and user-accepted.

but people don’t like it b/c it’s big, it’s not accessible, and it’s not more efficient than using a regular cord (note, fujitsu’s technology is more efficient, charging batteries 1/15th times faster)

we could also look at hand cranks/wind up methods of charging batteries.

Recharging notebook computers is one of the few tasks that requires such little power that a crank generator can adequately meet the power requirement. The smaller and more efficient the laptop, the easier it will be to charge. With a modified 12v drill as the hand-crank power source, your laptop can be up and ready to compute.

and there’s solar power
lap top bag with solar panels that can charge your lap top when you’re outside
“solar rolls” that you can plug your lap top into (often used on camping excursions)

Before your team begins your field research, I will suggest a few things. First of all take a look at the power point that I presented on Innovation: http://rand.gatech.edu/wp-content/uploads/2010/11/What-is-Innovation1.pdf. This will give your team a good idea of what type of information you want to gather through research. You can take a few approaches to this research. You can perform observational research, interviews, or document your own experiences, or as a group you can do a combination of all three.

To perform observational research, you would want to pick the right setting and the right time to go to an area and watch how people act and use the space. In doing this activity all you are doing is watching, taking pictures, and taking notes on what you see.

Your team could also interview some people. You can choose to interview people who are disabled, as well as experts. In interviewing people make sure that you use open ended questions, and focus on asking people questions about their experiences, try and stay away from asking them directly if they like your idea or asking them to provide you with a solution. Most people are not trying to solve the problem you are so they are not thinking about it all the time, and are not very good at articulating potential solutions. That is what you guys do as designers. The research should be used to identify the problems and learn more about the experiences people go through.

Lastly you can simply document your own experiences. Your team can plan an activity. Your team would then document your entire experience, pain points, things that worked well, ect.

Through the research, Capture what people do, how they behave, document other objects that are involved in the experience, document the environmental characteristics that affect the experience, document the messaging and signage that helps guide people, document the services if any that are being provided as part of the experience. Additionally document your own personal experiences, how did you feel, were you confused, stressed, where did you look for answers, ect

The more you document the more insights your group can gather which will lead better brainstorming and ideation.
