IBM Mouse Helps People With Shaky Hands

By Roland Piquepaille

A friend of mine who worked for free to help senior citizens to use computers once told me that the biggest hurdle was not technical -- people can learn during all their lives -- but physical. Many old people have trembling hands which prevent them to use a mouse to point and click on a small icon on a computer screen or a link on a browser page. Now, according to this article from ExtremeTech, IBM has unveiled a mouse adapter which treats these tremors as "noise" by filtering out the unintentional movements of the hand caused by a tremor. This new mouse will also help the ten million people which are affected by this genetic disorder every year, and who aren't necessarily old. This adapter will be sold for about $100. Read more...

Let's start with some pictures.

Here is how it works.

The new mouse treats the hand tremors as noise, and uses algorithms based on image-stabilization systems used in digital cameras.
[As you can see on the above pictures,] the mouse includes a physical dial to control the sensitivity of the mouse, as well as how quickly the user needs to double-click. Normally, these functions are handled by software controls -- which require a mouse to adjust.

As I wrote above, this inability to precisely use a computer mouse doesn't affect only the elderly.

Although tremors are usually associated with the elderly, a type of tremor called Essential Tremor is actually a genetic disorder that affects 10 million people per year, according to the International Essential Tremor Foundation (IETF).

This mouse adapter will be distributed by Montrose Secam, a British electronics company. You can buy it now for £67.50, 119.00 euros or $107.00, depending on where you live.

For more information, you can read these two articles from the Mercury News, "Algorithm box smoothes hand tremors on mouse," and from the San Francisco Chronicle, "Helping hand for those with shaky hands."

Finally, you might want to read this IBM press release, "Mouse adapter gives computer access to millions of hand tremor sufferers," which offers additional details and links.

Famous quotes containing the words shaky, people, hands, mouse and/or helps:

    Nothing is plumb, level or square:
    the studs are bowed, the joists
    are shaky by nature,
    Alan Dugan (b. 1923)

    The people needed to be rehoused, but I feel disgusted and depressed when I see how they have done it. It did not suit the planners to think how they might deal with the community, or the individuals that made up the community. All they could think was, “Sweep it away!” The bureaucrats put their heads together, and if anyone had told them, “A community is people,” they would not have known what they were on about.
    May Hobbs (b. 1938)

    Keep your hands clean and pure from the infamous vice of corruption, a vice so infamous that it degrades even the other vices that may accompany it. Accept no present whatever; let your character in that respect be transparent and without the least speck, for as avarice is the vilest and dirtiest vice in private, corruption is so in public life.
    Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)

    An epicure dining at Cree
    Found a rather large mouse in his stew.
    Said the waiter, “Don’t shout,
    Or wave it about,
    Or the rest will be wanting one too.”

    Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.
