What’s a Wearable?A person’s computer should be worn.Interactive with the user based on
the context of the situation.Act as an intelligent assistant.

What is MIThril?The next generation research
platform for context aware wearable computing.
Developed by researchers at the MIT Media Lab.
Goal: develop and prototype new techniques of HCI for body-worn applications.

The MIThril VisionPeople vs. Users
starts with “people”, not “users”. Support people in their daily lives. Build technology that is: reliable,
comfortable, useful and makes max use of time and user’s attention.
Good HCIContext Awareness

The Memory Glasses ProjectGoal:
produce an effective short-term memory aid and reminder system.
Require a minimum of the wearer’s attention
Problem of the Context Blind System: The need for effective logistical and memory aid is on the rise.
![Page 15: Wearable Computing - MIThril](https://reader035.fdocuments.in/reader035/viewer/2022062410/56815c78550346895dca8ff3/html5/thumbnails/15.jpg)
The Memory Glasses ProjectSolution:
Provide a proactive, context-aware memory aid.
Applications: substantively Unimpaired Wearers Normal older people Amnesia patients Agnosia Patients Patients with other disorders

The Context Aware Cell Phone Project
Problems: A cell phone depends completely on the
user to manage its state. Solution:
Build a phone that could determine the user’s circumstances or context.
Automatically change the behavior according to the information

Wild IdeaSpectral Camera
A camera that can record full spectra across its field of view rather than red, green and blue.
Problems:Creating separate filters for more than a
hundred spectral bins is very painful.
![Page 19: Wearable Computing - MIThril](https://reader035.fdocuments.in/reader035/viewer/2022062410/56815c78550346895dca8ff3/html5/thumbnails/19.jpg)
Wild IdeaProjector Project
Problems:Heads-up displays only work for the person wearing
them not a group of people. Solutions:
Mount a steerable laser on the borg, andto paint vector drawing on flat surface.
However… Small steerable lasers aren’t easy to come by.

Wild IdeaLeopold Project
Goal:To determine the wearers hand and feet
positions. Solution:
Connect the wearable to position sensors and accelerometers.
