The 2013 International Consumer Electronics Show will kick off at the Las Vegas Convention Center Tuesday, and several Minnesota companies will vie for attention at the world’s largest technology trade show.

Maplewood-based 3M Company will showcase an 84-inch touchscreen table prototype that can respond to different touch inputs at a time. While the device is not out on the market yet, the company expects several businesses, including museums, retailers, casinos, and restaurants, to be interested in it.
 
In addition to 3M and other big names, such as Best Buy, Imation, Polaroid, and UnitedHealth Group, the following smaller local companies will showcase products and services:

• Afinia (Chanhassen): Offers 3-D printers geared towards consumers and beginners that are said to be easier to use and set up than 3-D printers built for industrial use.

• Canopy Company (Minneapolis): Its Sensus iPhone case has touch sensors built into its back and allows users to control the phone from the rear.

• Finder Codes (Minneapolis): Developed a digital lost-and-found system that uses QR codes to help recover lost items, such as electronic gadgets. The system includes physical tags that can be attached to phones, computers, and other devices. If someone finds a lost object, he or she can scan the QR code on the tags to get in contact with the owner.

• Ergotron (St. Paul): Its line of interactive TV mounts only require a light tap to tilt and swivel in order to provide the best viewing angle.

• Sanus (Eden Prairie): Also designs and builds TV and audio/video system mounts that can extend, retract, tilt, and swivel to provide the best viewing angle.

• Wadia Digital (Plymouth): Offers a wide range of audio playback products, including the iTransport iPod docking cradle, which specializes in retrieving music signals from iPods to be played on high-end audio systems for “CD-quality” playback.

 
Some local companies that participated last year are making appearances this year as well. Among them are Edina-based Bracketron, which provides mounting solutions and accessories for various mobile and handheld technologies; Rochester-based Noetic, which offers products and accessories designed to seamlessly integrate computers and consumer electronics into users’ living rooms, cars, and on-the-go lifestyles; and Minnetonka-based The Navvo Group, whose VOCO voice-controlled multi-room home media system allows users to wirelessly stream music and video from multiple sources to different parts of their home.
 
This year’s Consumer Electronics Show will run through January 11 and is expected to feature products from more than 3,200 companies on 1.87 million net square feet of show floor. More than 20,000 new products are scheduled to debut at the show.
