(2007) 1.Select one specific task that can be done with a mobile phone (or portable digital device). You can think of very specific users or contexts of use. 2.Think of different modes of interaction for a selected task beyond screen-based one such as sense of sound, touch, smell, or even taste. 3.Problem: analyze problems with current screen- based interaction for a selected task and describe why you choose a certain mode of interaction as appropriate for the selected task. 1.New design: specify the steps of interaction for the selected task, for example, in terms of user goal, input, output, etc. 1.New experience: think of how such new mode of interaction would change user experience compared to current screen-based interaction. 2.You could use any types of design tools or methods that would best represent your new design--from hand-drawing sketch, photoshop, paper prototype, or cardboard mock-up. 3.If you find an interesting design example and want to modify it for your new design, that is fine—just reference the example.

Even moderately skilled typists can type without looking at the keyboard or at a screen. The problem I attempted to tackle is the problem of needing to type when a screen or keyboard would get in the way. While completely valid in certain situations, text to speech technology can not be used in every situation, so I focused mostly on situations where that technology would also be inhibitive. Examples of when this is the case: Texting, composing an , or taking notes while walking. The screen is not the focus; where you are going should be the focus. Text to speech could be used here in some situations, but if you’re composing a message containing sensitive information then text to speech would not be ideal. While taking notes during an interview in a situation when audio recording would be difficult and a laptop would close you off too much from your interviewee. During a meeting or in class when you should be paying attention but feel that your time could be spent participating in a more personally fruitful endeavor.

The “airboard gloves” provide the user with the same force feedback that a real computer keyboard would. It functions through a series of synthetic, constrictable fibers (much like synthetic muscle fibers). It also uses tiny air bags that can be filled to simulate pressure, similar to the TeleTact Glove developed by the University of Salford [1]. The glove provides the user with four levels of feedback. The user can feel the home row bumps on ‘f’ and ‘j’ This feedback is provided by constrictive fibers that run horizontally. The user can feel the keys of the keyboard as he or she moves his or her fingers across the air-keys This feedback provided by the same fibers that provide the bump feedback. The air-key gives resistance when pressed This feedback is provided by constrictive fibers that run vertically, along the finger The user can feel his or her fingers resting on a key. This feedback is provided by the small airbags that inflate within the glove to simulate pressure.

The user will know when he or she can type because they will feel the home row markers of the ‘f’ and ‘j’ key. As the user moves his or her fingers through the air, the glove provides them the same feedback that they would get from using a keyboard. If they move their hands across the keyboard, they will feel the keys move under their fingers. When they press on a key, they will feel it depress, and will reach a point of total resistance, indicating to them that the key is fully depressed. The main issue that needs to be addressed is: how do the users review what they’ve typed? A screen is out of the question, because the situations in which these gloves are used require a more subtle solution. Instead, we can use speech to text technology and a hidden speaker. A possible solution is to use similar technology to the implanted cell phone / tooth project [2]. Instead of a tooth, though, it would be less invasive to use something external, but still able to send vibrations through the skull to the user’s eardrums. A plausible solution would be to attach something similar to Merkury’s vibration speaker to the user.
