Ahmed S. Khalaf


I am a senior PhD student in the Computer Science Department at New Mexico State University.

I am working with Professor Toups and Professor Tran on “Wearable Interfaces to Direct Agent Teams with Adaptive Autonomy” project. The objective of this project is to develop wearable interfaces for the direction of a team of software agents that make use of adaptive autonomy, and ascertain the effectiveness of our interface designs and agent-control algorithms. My research focuses on discovering and developing effective interface mappings from individual mobile input modalities (e.g., touch screen, free-air gestures, device- based gestures).

Currently working on:

  1. A Comparative Study of Hand Gesture Recognition Devices.
  2. Framework for Wearable Input Devices.
