For this assignment I decided to design the electric screwdriver with OXOs design practices in mind. Of the three options, I thought this one sounded the most exciting in terms of its features and shape. Once I gathered the necessary tools and information, I dove into the design process.
DesignI wanted to use OXOs design practices to design a screwdriver with a comfortable grip and intuitive control. I begun by drawing up some sketches using OXO devices like vegetable peelers and other simple handheld tools for reference. I wanted to emphasize the shape of the handle and make sure that the button locations were logical and quickly accessible.
. I came up with a variety designs thinking about the ways a user could interact with the device. Overall, most of my designs had the same shape but some of the features jumped around.
Once I settled on a design, I began to plan what materials Id need to build my first prototype. PrototypesI used thick paper and tape to create my first prototype for a quick and rough go at capturing the basic shape and visualizing the main features. I followed my sketches to try and form the handle shape.
Once the prototype was finished, I conducted a few informal user tests to determine what aspects could be changed. I noticed that it would be better to switch the placements of the LED screen and speed settings. This seemed like a more logical set up as the the setting buttons would be grouped together.
I created a couple more sketches thinking about changes I wanted to make and then set out to create a second prototype. Along with the placement swapping, I realized I should add an off option to the speed settings to avoid accidental activation.I also improved the fluidity of the screw head selector making it closer to the ideal way it should function.
In order to create a more accurate sense of the weight , I used foil and clay to build the device. I made my changes for the button and screen locations and used the clay to try and achieve the OXO like handle shape. This prototype was successfully weightier than the previous one.
AnalysisOnce the second prototype was completed I began critiquing and gathering feedback from my peers. One feature I noticed while evaluating was that the spin dial for the head selection could have been reversed: instead of spinning a selector to land on a head, one could spin on the heads and line one up with a static selector. This could have made the head selection process more streamlined and might have matched more users mental models but it is hard to tell without testing it.
Another interesting idea from critique was that the speed setting would mostly be the most commonly used setting making it more logical for that feature to be the main thumb control. This would then require the the power button to be on the reverses side of the device making it more like a trigger. I realized that I hadnt thought about the actual use of the speed settings and how they play a major role in giving the user control as they use the the device.
In my next iteration of the device, I would definitely take this into account.

An HOA member dug a hole in my yard saying it way a drainage basin, the water is crossing the road uphill from my house, what can I do to stop him?
Well, if the hole is already dug, then you cant stop him. Its done. Did the HOA send you a notice that work would be done on your property?
If so, then your time for doing something has long passed. If not, then you need to contact the HOA (in writing) and ask what is going on, why you werent notified, and how the HOA intends to compensate you for the use of your property for its drainage basin. You can also contact your city/county planning commission and ask whether the drainage basin was authorized and if not, what the commission can do about it.
