Problems solved by technology

However, user interfaces that require on-screen cursor navigation or rely heavily on visual feedback are not suitable due to the limited screen size of wrist-worn devices.
[0012] Also, any user interface that requires the user's visual attention can be problematic in a mobile environment where the user must be aware of their surroundings
[0013] Therefore, there is currently no method for inputting information that is particularly efficient and that solves the remaining problems of wrist-worn devices, such as requiring navigation, which increases interaction time, is obtrusive, and requires the user to look at the device

Embodiment Construction

[0042] Referring to Figures 1A and 2A, there are shown plan views of wristwatch computers 10 and 20, respectively, in which the present invention may be used. Although the invention will be described with reference to the embodiments shown in the drawings, it should be understood that the invention can be embodied in many alternative embodiments. In addition, any suitable size, shape or type of elements or materials could be used.

[0043] The physical design of watches hasn't changed much over the decades, even as the range of features they offer has expanded. Traditional mechanical watches as well as modern computer watches share common features that can be exploited in the design of the watch-computer interface: they have a face / display, and around it, a bezel / display frame.

[0044] The wristwatch computer 10 shown in FIG. 1A is the IBM / Citizen WatchPad, a preferred computer for use with the present invention. The watch computer 10 has a transparent touch screen 12 surro...

Abstract

An input method that is based on bidirectional strokes that are segmented by tactile landmarks. By giving the user tactile feedback about the length of a stroke during input, dependence on visual display is greatly reduced. By concatenating separate strokes into multi-strokes, complex commands may be entered, which may encode commands, data content, or both simultaneously. Multi-strokes can be used to traverse a menu hierarchy quickly. Inter-landmark segments may be used for continuous and discrete parameter entry, resulting in a multifunctional interaction paradigm. This approach to input does not depend on material displayed visually to the user, and, due to tactile guidance, may be used as an eyes-free user interface. The method is especially suitable for wearable computer systems that use a head-worn display and wrist-worn watch-style devices.

Description

technical field [0001] The present invention relates generally to apparatus and methods for use in mobile computing. More particularly, it relates to apparatus and methods in which small devices can easily and efficiently process input data. Background technique [0002] In general, a variety of devices are available for performing mobile computing functions. These devices include PDAs, computerized watches or wristwatch computers and other mobile devices. [0003] Mobile devices are often used in situations where the user's attention is divided between the environment and using the device itself. If a mobile device "pushes" information to the user at unexpected times and / or requires the user to take immediate action (such as acknowledging a notification), a method is needed that allows the user to perform these tasks as quickly as possible in order to minimize the time allocated to using the The input method of the time of the device. [0004] Additionally, for the inpu...
