Tactile feedback on touchscreens – is it worth it?

Quite a few new handsets are offering tactile feedback on their touchscreens, like the Blackberry Thunder, pictured above. I can’t help thinking that because the manufacturers can’t do multitouch properly, they are opting to enrich their feature lists in other ways.
Is it really a valuable feature? In concept, tactile feedback is wonderful. It is the reason that real keyboards are way easier to use than on a touchscreen. However, the execution is quite different. Consider the micro-interaction of pushing your finger down on a key on a real keyboard or keypad:

  1. You line your finger up as best you can
  2. The tactile landscape of the device tells you whether you have lined up your finger properly or if you are overlapping with other keys
  3. As your finger presses down, you get a satisfying ‘click’, letting you know that it worked.

In other words, you get tactile feedback before the act as well as after the act. Most important is the feedback beforehand, since it allows you to adjust your action accordingly. The reason why all these new handsets are missing the point is that they only give after the act feedback. It’s a vague confirmation. Essentially it’s saying “Yeah, you pressed a key. You wont know which one, though, until you look at the screen.”

So, what should they be doing instead? Concentrating on honing the primary features. Adding enhancements that offer deep, lasting value rather than just an additional bullet point on the promotional materials.

“Reply to all” on SMS would be good for everyone

Some passing thoughts:

Wouldn’t it be so useful if you could have group SMS conversations via a “reply to all” feature, just like you can with email? Imagine how much more profit the mobile operators could be making. What a lost opportunity!

By the way, if you like mulling over half-baked ideas, you should check out halfbakery.com. It used to be a favourite of mine a few years ago. Ideas on it tend to be quite fun in a brainstormy outside-the-box kind of way. Good for creative thinking.

Oh, and another thing about SMS. Did you know how ridiculously easy it is to send a spoofed SMS these days? It’s scary.
