UX of ITV: The User Experience and Interactive TV (or Let's Stamp Out Bad Remote Controls)

I prefer to watch our flat-panel HDTV in the dark, and usually I watch something I've DVR'd.  Because of the nature of my remote control, I often have to interrupt the immersive experience, turn on the light, poke at the buttons, and start over again.


Not long ago, I had the flu and I thought I'd try out the interactive channel from my satellite TV provider.  My interactive experience was about the same as interacting with the DVR!

What the satellite TV company offered was not really ITV.  It was BIRC.  Bad Interactive Remote Control.  You know what I'm talking about.  In the era of the WiiMote, most of us still have to interact with our TV systems as if were 1982.

There is hope!
A good number of researchers are working hard to make the UX of ITV, including mobile TV, a reality.   If you are reading this post, you most likely will appreciate some of the articles and links below:

There is too much to summarize, so here is a copy of the press release, from Steaming Media:

WebTaps Releases HDTV Web Browser

WebTaps announces the availability of the first HDTV web browser with integrated intelligent virtual keyboard and screen scaling technology


Rockville, Maryland (December 17, 2009) -

WebTaps, a developer of web browsing software for HDTVs and touch screen PCs, today announced the availability of the WebTaps HDTV Web Browser. The browser is designed to be used from across the room in a TV viewing environment to augment or replace the content otherwise available on the HDTV. WebTaps offers the only HDTV web browser that automatically scales web content to the full size of the HDTV screen and includes a truly intelligent virtual keyboard. The patent-pending intelligent virtual keyboard knows when and where to appear on-screen so that text can be easily entered while watching from across the room.

"WebTaps has finally brought the full internet, including access to every website, to the biggest and best screen in the home - the HDTV," said Scott Lincke, CEO of WebTaps. "WebTaps enables people to sit back and comfortably access great sites like Hulu.com, Facebook, YouTube, and Google. They can easily find content and sit back to watch together with their friends and family instead of staring at a laptop screen. WebTaps really transforms how people can use their HDTV by bringing an infinite supply of content, unlimited by their cable company or over-the-air TV signal."


To get started, users of PC-connected HDTVs download the free software installer from www.WebTaps.com. No user signup is required. The user simply selects their country and language and the software is ready to use. A localized content guide is presented, showing great content sites. Alternately, users can enter any web address or search any of the leading search engines.

WebTaps plans to distribute its products through retailers and PC OEMs in 2010. "We are pleased by the reaction to our products," said Scott Lincke. "Web browsing on HDTVs saves people money spent on premium services and they tell us that it gives them even more functionality than their DVR since they don't have to think ahead about what they want to record. Suddenly anything available on the web can be watched on their big screen TV."


WebTaps HDTV Web Browser product evaluation kits are available for qualified press personnel. In addition, WebTaps will have representatives available to answer further questions at the Consumer Electronics Show in January, 2010. Please contact WebTaps at pr@WebTaps.com for more information.

HDMI Version 1.4, 3D HDTV, and Wireless HD

My husband surprised me with a new HD TV to replace the old non-HD "clunker" that was taking up space in an armoire in our bedroom.  I went to attach my HD video camera to the new TV, and realized that three-foot HDMI cable was much too small.   Knowing how fast everything changes with technology, I decided I should research HDMI before setting out to purchase a longer cable.  

There is more to know about HDMI than I thought!   Here's what I found so far:

There is an organization dedicated to HDMI standards, HDMI Licensing, LLC that provides a wealth of information about HDMI.  It's worth taking the time to review the information contained on HDMI website, specifically, the following two links:

• FAQ for HDMI 1.4

• HDMI 1.4 Specification Features (pdf)   (Steve Venuti, HDMI LLC 2009)

Key points about HDMI 1.4 from the HDMI website and the Specification Features overview:

• Consolidation of HD Video, audio, and data in a single cable.
• Enables high-speed bidirectional communication.
• Enables IP-based applications over HDMI. (Ethernet)
• Transfer speeds up to 100Mbps.
• Supports audio return channel.
• Can support up to 10.2 gigabits per second of bandwidth transmission
• HDMI 1.4 is the latest standard. It includes definitions for common 3D formats and resolutions, up to 1080p.
• HDMI 1.4 supports 4K x 2K resolution, which is the resolution of state-of-the art digital theaters and up to 4 times the resolution of 1080p.
• Allows for the optimization of picture settings based on type of content.
• Supports digital still camera-specific colors.
• Allows for smaller HDMI connectors, ideal for portable devices.
• Provides "High Definition Everywhere" support, with an automotive connection system designed to work effectively in vehicles.

About HDMI Version Numbers (from the HDMI website)

"HDMI version numbers are used by manufacturers to identify a set of features. To help you shop for the features you want in a cable, the HDMI licensing authority has created standardized names for certain key features. Here are a few:

• Deep Color refers to monitors that can display a greater number of colors than traditional TVs, billions or trillions of colors rather than millions.
• x.v.Color refers to an expanded, "wider" color gamut that includes colors not traditionally available in TVs. The x.v.Color space incorporates a much larger portion of the visible color spectrum than the older RGB color model.
• Standard and High Speed refer to two grades of HDMI cable, tested to different performance metrics. A Standard cable can transmit a 1080i signal for 15 meters (49 feet) or more, while a High Speed HDMI cable can transmit a 1080p signal for at least 7.5 meters (25 feet)."

Podcasts about HDMI

The podcasts focus on HDMI 1.3, but also provides information about HDMI for the future

• An Insider's Guide to HDMI, Part 1
• An Insider's Guide to HDMI, Part 2

The podcasts feature interviews with Jeff Park and Steve Venuti from HDMI Licensing, via  Dolby Labs "Dolby cast".  Topics covered include HD devices, HDMI feature sets, capabilities, and HDMI versions.  The podcast also touches upon previous problems with firmware deployment, as well as wireless HD, which is not part of the HDMI specifications.

Philipp Geist: Blending the Physical with the Digital; Google TV/Leanback, Vimeo's new Couch Mode, oh...and ViewSonic's 3D (glasses-less) pocket camcorder...

I'm thinking about getting one of the new "internet ready" TVs.  I have a serious reason to do this. I'm working on some interactive video projects, and a couple of my projects are geared for teens and young adults who have autism.*   My hunch is that many of my students would like to watch- and interact with-content optimized for Google TV and Vimeo's Couch Mode.  The content is designed to look good on larger high-resolution flat-screen displays, and I'm sure it would be great on my school's newer SMARTBoards.  I need to learn more about  developing applications for this purpose.

(Currently I use my HP 22-inch TouchSmart PC to view web-based video content, and to evaluate websites that provide "touchable" and interactive content that might work well on interactive whiteboards.)

At any rate,  I've been looking for great videos that have the potential for use at work with older students who have autism. I'm also looking for effective ways that the students can use to interact with multimedia and video content. This is important, since the students have minimal verbal communication skills, have limited reading ability- if they can read at all.  They learn about their world through visual means, and are capable of learning much more - but not through traditional means.

Since our school is focusing on globalization and learning about the cultures of other countries, I've been on the lookout for some interesting videos that might appeal to our students.  

Today I came across a great find- Philipp Geist.  Who is Philipp Geist?  According to his bio, Philipp works internationally as a light and multi-media artist in the mediums of video, performance, photography and painting. Some of his work focuses on architecture, history, and cultural heritage.  A good example of his work is the installation he created for a festival in Thailand in 2009:

Bangkok / Thailand 4D Light & Sound Installation by Philipp Geist (23Min) from Philipp Geist | Videogeist on Vimeo.

"The one-hour show is the central part of the celebrations and will be seen by thousands of visitors.  It interprets artistically the king's life and his work dedicated to public welfare. The art installation combines images of the kings and his social projects in the past and present with 3D animations of Thai natural and cultural heritage and abstract painterly passages." (from the Vimeo site)

HIGH-RES MULTIMEDIA WEB CONTENT ON LARGE PANEL HD TV!

This might boost holiday gift sales and in turn, give a little jolt to the economy. To do my duty for my country, I will continue to research Internet TV as I narrow down my selection for my new Internet-ready TV.... Below is some Information about Google TV, Google Leanback, and Vimeo's Couch mode that I've recently gathered to share with my IMT followers:

GOOGLE TV:  "The web is now a channel"

"With Google Chrome and Adobe Flash Player 10.1, Google TV lets you access everything on the web. Watch your favorite web videos, view photos, play games, check fantasy scores, chat with friends, and do everything else you're accustomed to doing online. Plus, the world's best websites are now being perfected for television -- check out our Spotlight gallery for examples."  "The worlds' favorite websites are being tweaked and perfected for the television." -Google TV

I'm not too excited about the design of the application that transforms your Android phone or iPhone into a remote control.  I hate most remote controls.  According to Google TV, multiple phones can control the same TV, and you can use your voice to search, which seems like it would be a good thing...  I wonder if they tested this out with real families, not just families of Google TV techies .

GOOGLE LEANBACK Video (Integrated into GoogleTV)

Google Leanback 
When I visited the Leanback website, I encountered the following screen with a suggestion that I type in what I was looking for.  I typed in "lynnvm", the name of my YouTube channel.  Apparently Google provides you with a randomly generated featured video that appears in the background that has nothing to do with what you are looking for.  


In this screen shot, my YouTube channel offerings are in the foreground. "Maleficent Halloween Tutorial" is what played in the background: 

VIMEO INTRODUCES COUCH MODE: Vimeo's version of Google's Leanback is Couch Mode.  It is optimized for use on Google TV, so that makes things less complicated in the world of videoviewingland.   According to Ryan Hefner's article on the Vimeo staff blog, "Couch Mode is a special new section of Vimeo that allows you to watch collections of videos (such as Staff Picks, your inbox, your videos, etc.) completely uninterrupted like a TV channel."
Couch Mode works on computers, but since it relies on HTML5 and CSS3, without Flash, it only works with Chrome and Safari browsers.  For more information, see the video below:

MeeGenius If you are a teacher, parent, kid, or lover of children's books, visit this interactive website ASAP. It is optimized for Google TV and works nicely on touch-enabled screens and devices.

As I was wrapping up this post, I came across information about Viewsonic's new 3D, glassesless pocket camcorder.  I'll update information about this new gadget when I have a chance to learn more about it. !

Comment: The idea of developing interactive multimedia apps in 3D intrigues me. At this point, the technology is too new for an "armchair technologist" like me to pursue with my incredibly busy work obligations.  I don't have the money to buy a 3D video camera.  But I might try this out, if it is true that it only costs $238.00!

* About me:  
I presently work full time as a school psychologist at a high school and at a program for students with more severe disabilities, including autism.  The students I work with have made amazing gains through the use of interactive multimedia applications, and also have responded well to video presented on the large IWB screens.   


I went back to school to take computer courses, initially so I could make interactive multimedia applications and games. I continue to blog about interactive multimedia,  emerging/ new technologies, and topics related to post-WIMP HCI/UX/ID/IA.  Although my "spare time" is limited,  I try to keep up my technical skills whenever I can by working on projects that can support the students I work with.
