Function
The AlphaSlider interface was originally devised in 1993 and promoted by Ahlberg and Shneiderman. The essential components of the AlphaSlider are the same as that of the drop-down listbox. There is a slider area, a slider thumb (the square in the middle that a user can directly drag on), and left / right arrow keys. The function of it is identical to that of a drop-down listbox, except for its vertical orientation.
Pros
The advantages of this AlphaSlider approach are:
- there are no typing errors
- performance increases as the number of words per entry increases
- keyboards are not necessary
[Osada et al., 1993]
- due the small size of Alphasliders, they can be placed on small displays, like those of mobile devices.
Contra
The disadvantages of the current implementation are that:
- the number of entries is limited by the number of pixels
- Alphasliders also does not allow users to input words freely
[Osada et al., 1993]
Conclusion and Future Direction
Important items to examine are:
- slider design when the number of entries exceeds the number of horizontal pixels
- performance when sliders and buttons are made of hardware devices
- combination of AlphaSliders and other information visualization techniquges
[Osada et al., 1993] With good use of feedback techniques, the Alphaslider is a powerful, compact, and rapid way of selecting items from lists. [Ahlberg, Shneiderman, 1993]
