Design Exercise: bus stop UX

In Dan Saffer's "Designing for Interaction" he lists several real-world opportunities for improvement in UX. One of these examples is "waiting at the bus stop with no idea when the next buss will arrive." Well, as I was waiting at the bus stop, with no idea when my bus was supposed to arrive when I came up with an idea: A bus stop kiosk (obelisk) of sorts. Basically the idea is to replace the current road-side signs and replace them with solar powered towers that notify people how soon their bus should be arriving.


How it would work
As the bus passes each stop on its scheduled run, it sends a geolocation signal the next several stops informing them of the bus's current location. This would pair with data taken on average travel time from stop to stop. The result is a system that can produce meaningful information to passengers.

Implementation
  • Each bus would need to be equipped with a device that allows digital signaling between stop and bus

  • Each bus stop would need to be equipped with a similar device, and a power source (ideally solar)








The Rules
  • Depending on the distance the bus is to the actual stop, the light matching the bus number will begin to pulse more rapidly on the corresponding panel

  • Any stop the bus passes will reset to a default signal (dim light and very slow pulse)

  • A route which is not in service for that day (or at certain times of the day) would show no light at all at each applicable stop




So maybe the execution isn't perfect, but the idea is there. I took a stab at this challenge in an afternoon: what would you do differently? What did I miss?

Video Games won't need controllers soon

Skinput



Project Natal



And then this dude





The future of gaming is bright. These UI could serve so many more users beyond entertainment. The Nintendo Wii has already gotten a lot of praise from physical rehabilitation centers: what about motion controlled training for sports events? What if Agoraphobics could practice driving a car using Google Earth data? Soldiers could experience close quarters combat without risk. Rich experiences ahead!

Design Exercise: Nutrition fact labeling

I am not a fan of the current FDA regulated Nutrition labeling. Counting calories is difficult enough but what about the people interested in measuring their daily protein intake? The problem is that nutrition labeling is an overly complicated and insufficient means of 'being informed' about what you are actually eating. Serving Sizes are always unique and never quite accurate as some self serve drinks in cold cases contain 2 servings. Let's think about this for one second. You're at Target, you reach into a cold case for something like a Snapple but never bother to check the nutrition label because you assume that it's healthy. I mean, just look at it, graphics of fruit and labeling like "contains REAL fruit juice"! The sad truth is that these products usually contain a second serving and consuming an entire bottle spikes your blood sugar levels and then before you know it you've consumed the same calories you could've had by eating a healthy snack that would have made you less hungry for a longer period of time.

Below is an exercise (definitely not THE solution) in labeling 4 different foods nutrition levels calories for calorie. Regardless of serving size, for every nibble, bite or entire package you consume-your nutrition level is reflected. The formula follows the FDA recommended intake of Carbs, protein and fats per calorie.
Where 2000 calories = 65gFat(585calories) + 300gCarbs(1200calories) + 50gProtein(200calories)


First we have a nice juicy-carcinogen-filled big mac.
Carbs are slightly low, protein is very high and fat also very high. If you ate Big Macs for breakfast lunch and dinner your cholesterol levels would rise from the fat and proteins but no energy to maintain a healthy heart without carbohydrates. Of course, we already know what happens when you live off of McDonald's food...


Our next contestant is Oreos. Chocolate + lard. YUM.
Oreos are a staple of the vegan diet because they contain so many synthetics they don't include any organic ingredients derived from animals. Oreos are a nice fit for the carbohydrate intake but imagine how weak you would be and overweight...Now think about obesity in American children and diabetes. Any relationship? Also, I read that sales of double stuffed Oreos far surpass regular Oreos nowadays.


One potential problem with this design system is that foods which are generally acknowledged as 'healthy' might have readings which seem off the chart or unhealthy. Below is an example of how Almonds would rate.
There is possibility that a parent shopping for their child might see the high amount of fats as unhealthy. In reality a huge percentage of the fats in almonds are great for maintaining cholesterol levels. Ideally a diet including almonds would necessitate the rest of foods eaten throughout the day being low in fat, high in carbohydrates, and stable protein levels....Wait that sounds like Fruits, Vegetables and Dairy products....


Finally we have Apples.
You can clearly see that apples are a bit higher than the FDAs recommended carbohydrate intake-severely low in protein and fat. This is why you should not sustain yourself on Apples alone. Again, a well balanced diet is key.

What I've learned from this design quickie is that nutrition labeling is no easy task: but it isn't impossible. There just has to be a more effective way of communicating nutrition levels for consumers. My concept excludes the important information regarding Vitamin and Mineral intake so a subsystem dedicated to those would need to be implemented. Additionally I haven't listed a caloric intake so people counting their calories would be in distress! Whole Foods has implemented their ANDI nutrition rating but I'm not a proponent of their rating system. I have to give a huge shout-out to the Nuval Rating system for their work done so far. I'd like to see their identity system flushed out a tiny bit more but their heads are in the right places.
