2)    Controlled by phone, able to stream from phone

3)    Allow subscription to subscription based content providers

4)    Controlled by voice and integrated with google-maps. Automatically start a kids program based on time left to destination

5)    Connectivity with Bluetooth headphones for kids

2,3: Difficult to control while driving. Having to select from many options can cause overhead

6: Good to have feature, but might have low frequency usage  

Conclusion: Implement 1,4,5


7.     Summarize

I would recommend building a car TV that could be attached over the backseat of the car. It would be integrated with google-maps. It will be voice-controlled and automatically start a kids show based on time-to-destination. It will be equipped with Bluetooth connectivity to kids headphones.

This will be beneficial to the user, since they can decide on using the product on the fly while driving or when they sense the kids edginess. Its minimalist selection approach will free the user from making choices when in a hurry or driving. It will result in hassle-free road-trips.

Answer : You can design as you wish. This TV is sold both as a standalone unit 

Assumption: Driving rules still require driver of the car to not be distracted so usage allowed primarily in passenger seats.

Goal: Is the goal marketshare, revenueAssume goal is to capture marketshare considering numerous players already in this space.

Users: Car TV are generally used by people during long distance travel. Typical users are

  1. Families with kids (30-45 age group): Parents wants to entertain the kids during long travel. During short travel /local commute they do not wants kids to spend additional screen time
  2. Group travelers (20-35) : Friends travelling together on long distance rides
  3. Riders of driverless car: As self driving cars will become more prominent and main stream, car TV will be useful in keeping the riders entertained

I would select my primary user as families with kids  as they still need a way to keep their kids entertained on long rides. 

Use cases:

1. As a user, I would like a rich and wide selection of content  TV shows, movies, music, games (Impact  H, Complexity: M)

2. As a user, I should be able to easily and quickly search and select the content of interest (Impact H, Complexity H)

3. As a parent, I would like to control the content that kids can see (Impact H, Complexity L)

4. As a parent, I would like to set a time limit for viewing (Impact L, Complexity L)

5. As a parent, I would also like educational topics for kids so that they can learn as well as be entertained (Impact H, Complexity H)

6. Ability to play single or multi user games (Impact M, Complexity H)

7. I would like the capability to cast my phone's screen on the TV so that passengers can acess phone content such as yelp, maps, points of inetrest etc during travel (Impact M, Complexity L)

For this design I would like to focus on 1,2,3,5,7


1. This will be an android TV with integration of content from major players such  as Youtube, Hulu, Netflix, Spotify, Pandora, Show the grid view so users can easily select the content. There will be a companion app so parents can also select and control the content on TV from the app 

2. Integrate with Google voice assistance for one to be able to easity search and select the content.

3. Provide parental control settings so parents can control the content viewing from their app. They can prconfigure the selection on the app and only those channels are viewable on screen

4.Have a "education and fun channel". Parents should be able to add the age settings for chindren. The topics will then be populated based on age setting. These will be fun how to, do you know videos.

5. Based on age settings, one can explore single or multi user games such as word quiz, scrabble chess etc and play while they travel

Question: Design a TV for car

Context: Customers and Needs 

Who needs TVs in their cars? When do they need it? What kind of content?

- Families with your kids to keep them entertained on long drives in cars, RVs, private buses

- Luxury cab drivers to offer their passengers a experience to charge a premium.

- Drivers such as Truck Drivers needing a break and follow their favorite sports team.

- Drivers needing to use the TV for communication, coordination on the go with their customers

My role - as a TV vendor, who is wanting to release a new product in the marketplace, giving people a choice. Considering the current landscape, there is a TV viewing experience on family cars for kids. For them, a basic viewing and listening experience controlled by an adult would be interesting. For luxury cab drivers, a premium experience is key and the TV experience contributes to it as well. For majority of the truck drivers, they are usually riding solo and they are employed drivers. For them, the key is to catch up on events and tune into special events, 

Considering the above, if my goal is to increase expansion of my current TV product to fulfill the needs of new customers, expand the served segment, I would like to focus on making a TV for the luxury cabs or sedans. As a user, many times, I am stuck in traffic and have nothing better to do but it would be nice to catch up with favorite team. AFAIK, the car ride companies also make most of their margin on luxury makes and it would help shore up that margin.

User Cases & Prioritization: 

1.  As a user, I need to see my favorites on the go.  Such as a favorite sports team or yesterday night's big game. Frequency of Usage: High

2. I want to have a good viewing experience - I am willing to pay an extra dollar, good video quality, good sound quality - eliminate road noise, vehicle noise Frequency of Usage: High

3. I am buckled in but want to be able to make choices easily  Frequency of usage: High- 

4. I want to continue where I left off : Frequency of usage: High

5. I want to photos, videos, on a bigger screen some times since the ride may not be very long. : Frequency of usage: Medium

6. I want to catch up on news : Frequency of usage: Medium

7. I want to watch pay per view episodes: Frequency of usage: Low



Solution 1:

1. TV designed to work with a mobile phone so that mobile content can be cast on the TV screen. 

2. TV has accompanying head sets with noise cancellation speakers to eliminate road noise. 

3. Mobile video content provider of cjhoice providers their own choice - a movie/episode/podcast catalog 

4. Mobile apps cast on TV - provide all familiar controls, continue existing viewing habits

5. TV designed to fit within the car and work in both daylight and nightime - so light adaptive brightness control particularly important

6. Considering this is a mobile device, over the air updates to keep device healthy/update is important.

 Solution 2:

1. Provide a VR like head set instread of TV screen.

2. Accompanying mobile app allows theater like experience for existing content.

3. Provide link up to popular cable/broadcast channels to show 


Considering that this is first version and that there are lots of uncertainties, recommend #1 to gauge interest. Further, the TV could be a general purpose tablet with popular video content providers available for viewing, popular programs shared via rider profile.

Success Metric: Percent of cars activated with TV in area of launch, Percent of users watching TV per ride, % return users

Question: Design a TV for a car

C--> Comprehend the situation

  1. What is it? -- A TV that can be used in your car
  2. Who is it for? - Could be the driver (manual or self driven car) or the passenger (front seat/backseat) or both. Within the passenger realm, it could be families or commercial clients (such as taxi service or uber/lyft)
  3. Why do they need it? -
    • Drivers could use the TV to house all controls including GPS, engine health in the TV portal instead
    • Families on a long trip, esp with kids, need a TV to keep them entertained
    • Commercial clients on long trips could use it for entertainment/news on the go.
  4. How does it work?
    • Located inside the car and powered through the car's battery/engine
    • Space is at a premium so we want something compact and user friendly.


I --> Identify the customer

Assuming the interviewer has not given any particular direction, I would like to go ahead with the 

  • User persona bio - Families traveling in their car with their kids.
  • Reasoning - Higher market share (need to tease this out further)
  • Pain points/Motivations - Long family trips can be arduous and boring and it can be a challenge to keep kids occupied and busy for these long stretches
  • Goals - Be able to provide a source of entertainment for their kids, be able to choose/control the type of content that the kids

R --> Report the customer's needs

  • As a parent, I want a way to provide engaging and approrpriate content to my kids so that they are not bored during long road trips in the car.

C --> Cut through priortization

Top Customer needs:

  1. I want to provide educational content to my kids during road trips
  2. I want to set time limits on how long the content can be viewed by my kids
  3. I want a seamless way to control the settings of the TV from the front seat.

L ---> List solutions

  1. The TV should support integrations with various streaming/non-cable services 
  2. The TV should be able to support casting directly from a mobile device
  3. The TV should have a mobile integration with controls such as time limit, age limit etc for the parents to use.
  4. The TV should be able to support internet integration/support
  5. The TV should be able to support offline play from streaming services
  6. The TV should be able to support other engaging content such as educational games

E ---> Evaluate Tradeoffs

1MHMBSolution 2 solves for this in a way
2MHMAMost people have their streaming apps on their phones
3HMMAAn Android/iOS app will be the least invasive way to manage TV controls because existing integrations can be leveraged
4HHHCInternet support for moving vehicles is difficult because of lack of coverage in certain stretches
5HMHBSolution 2 could solve for this in a way but is definitely a nice to have
6HMHCThis is related to diversification of content which would require further exploration.

Thus I recommend moving ahead with Solution 2 and 3 with Priority A


S --> Summarize recommendations:

I would recommend that we built TV in a car to cater to the needs of families that use cars for long road trips. This TV should be fitted in front of the backseat for easy viewing access for the kids and should use a touch screen interface as space is limited and the controls such as brightness/volume can be managed directly from the screen and also allow headphone jacks and bluetooths support for the kids to listen to the content. 


The TV should have a mobile app integration that allows parents to remotely control the content displayed on the TV and allow them to set preferences on the type of content that is presented on the TV. They should also be able to set time limits on how long the TV can be viewed for. TheTV should also allow parents/kids themselves to cast content from their phones. Using the phone is a great way as these integrations already exist for mainstream TVs and the cost to build will be minimal and we can leverage existing integrations.
