Dear Car Makers: Please Hire People Like This



Why should we care about it from the perspective of mobile interaction design?

Modern Cars: most expensive, massive, largest power supply, slow OS, poor UI -> dangerous
-current UI: build buttons on touch screen -> no muscle memory compared to previous physical button design
-voice control is expected to be more interactive in cars

A New Car UI: How touch screen controls in cars should work (Matthaeus Krenn)
-not perfect, still requiring users to learn/memorize interface controls

-new trend in UI design for touch screens: a move away from skeuomorphic interfaces

What’s this? 
Actually, the Dash is a “smart” wireless ear headphone in the world and the aim is to achieve a better understanding of your skills, abilities (performance tracking) and health (body sensors) while doing the things you like. The Dash its hardware is below:










  


What’s the laundry list of features?
1. Wireless (Bluetooth 4.0, with support for high quality Bluetooth aptX )
2. Touch control (left ear for tracking, right for sound)
3. 4GB onboard storage for media playback (or use your phone)
4. Audio training feedback
5. An accelerometer
6. Heart rate monitor
7. Oxygen saturation sensor
8. "Transparent" mode (so you can hear ambient sounds without removing)
9. Waterproof to one meter


Let’s see the video.

What's interesting about the news?
“All-in-One” – a pair of these super-powered headphones
Music plays an important role in our daily life and it can provide us motivation and joy. However, to listen to music with headphones still has some drawbacks, such as cables tangles and pull at the headphone. Also, if accessing online music from a Smartphone, users still need to carry this device all the time. It’s really painful. The Dash has wireless stereo earphones and will playback music through a Bluetooth connection (Online) or use the built-in music player to play the local stored music (offline). Users can enjoy a freedom and comfort of movement. Also, the Dash can track your movements, such as pace, steps, cadence and distance, but not just be limited to regular outdoor activities like golf, jogging, tennis. If you love water sports, such as swimming, snorkeling, the waterproof feature still can work fine. In addition, the Dash has sensors to measure heart rate, oxygen saturation and energy spent and also offers the function of real-time acoustic feedback and keeps users safe. It even works without an attached Smartphone. Everything is controlled through gestures near the ear buds or by tapping on them. This is awesome for those people love working out. The Dash could become a truly remarkable addition to our lives and also change many users’ behaviors. 

What can you currently do with the Dash? 

The Dash can adapt to many needs.

Why should we care about it from the perspective of mobile interaction design?
Hardware 
























From the design principles:
1. Consistency: for this part, users still need to spend some time to get used to these gestures because left/right sides have different functions, and some gestures are not consistent with user life knowledge and experience like Play/Pause/Take a Call
2. Shortcuts: the designers use a function “Select a Playlist”, so users can cut down on songs selection.
3. Feedback: I am not sure if the designers offer informative feedback. If not, the designers should indicate error message when users’ wrong behaviors.
4. Prevent Errors: I think that the designer may not provide recover mistaken input.
5. Increase short-term memory load: complicated gestures may increase the users’ burden.

Software
The Dash also provides an App on Android phone and iPhone. However, I still cannot find this app from the Google play store and app store.














Based on the pictures, we still can judge from the design principles:
1. High Visibility: In the main menu on the top of interface, each concise icon has “blue color” to inform a user about the current status.
2. Good Consistency: the interface design is internally consistent. All items are the same so that users can get the hang of it very soon.
3. Bad Mapping: Some icons are difficult for users to know their function. Ex: Music playback from phone, track your performance, Measure your body vitals.
4. No shortcuts: It seems the Dash has no shortcut to enable users to set ‘favorites’ function.
5. Expect concise and graphical interfaces instead of many texts.
