    Anand and team,
    thanks for bringing this industry insight to us. I hope this finds its way into your testing regiment for phones and laptops. Driving home that there are three points of interaction with a device, screen, keyboard and touch pad (and audio and case rigidity) that differentiate today's brands from each other. All else is ARM and Intel anyway.

    Thanks
    P.S.: I realize that I Antennae design and other factors (i.e. physical button for voice command input) are great differentiators too.

    Maybe not for phones, but definitely for tablets, pen input is a must-have. Especially once x86 tablets start appearing more often and people start using real applications that require some semblance of accuracy. Don't be fooled by Windows 8 "Metro" or whatever they decide to rename it to, it might be a flop or the most successful idea ever and people will still need to run drawing or modeling applications or even games where a pen will always be preferable to a finger. Many games that were not designed for touch work just fine with an active digitizer pen instead of a mouse, and if they could run on my old HP tm2 then they will also run fine on the Ivy Bridge GPU.

    You are just publishing their marketing BS without knowing much about this yourself and that is problematic.
    It's like taking Nvidia's internal testing and claiming those are real perf numbers,would you do that?

    Anyway,looking forward to the next article on them to hear more about the keyboard tech they just bought.

    Well, I didn't know anything at all about how this worked. He specifically states at the beginning this is just the basics of how it works. Think of it as marketing BS, but most of it I found to be useful background information on how it works, and a tiny bit on what Synaptics says about their products (sure, marketing info, but not necessarily BS).

    I'm definitely looking forward to the next article with more details. Keep bringing us other bits on the edge of technology we usually don't read about Anand!

    Most of the paragraphs start "Synaptics claims", so it's not like he's presenting it as actual fact. Reply

    Do you have a smartphone? Every point in the video though a marketing test its true, and i really like they have deloped such sleek working touch surface, in fact the touch surface its really important for the quality and comfort, just like keyboads.

    I have a cheap Defy (also from motorola like the razor shown) and everything showed on the video actually happens a lot, on wet fails, its imprecise (but cm helped a lot with the tweaking!) and on charge its annoying.

    Another case its in laptops, i love to use the old solutions usually from Synaptics at HP and IBM laptops, but get a brand new laptop with an Alps or Elantech touchpad and its awful, imprecise, lagged, and overall, annoying too.

    There is no such thing called a capacitive field. I think you meant electric field. Reply

    I was going to say the same. Reply

    You are right. But If you've got many capacitors next to one another, it's not too wrong to call it a "capacitive field", just like a mine field or a flower field. Reply

    Maybe. But the article says that the transmitters "emit" a capactive field, which is "distorted" by our fingers. Reply
