HaptiCook

The Motors & Music module was an exploration into the role of haptics and sound as interaction modalities. The tools at our disposal was a motorised slider , a Plank (a repurposed hard drive with a Hall-effect sensor) and a custom Arduino with a 8/12 bit built-in synthesizer. The goal was too look out for interesting opportunities for design intervention where day to day interactions could be enriched by incorporating haptic feedback in them. HaptiCook was prototyped in two days as a possible future product.

The Concept

With the advent of induction cook-tops in most modern kitchens, cooking has become a very “silent” and “cold” task. Although it comes with its benefits of safety and energy-efficiency it also cuts off a large part of the feedback that traditional flame-based cooking gives. With HaptiCook we tried to make a device that could be used with induction-tops to give a rich feedback of the cooking process and also act as an alarm system when one is away from the kitchen.

How it Works

The main interface element is a slider which lets you set a temperature you want to cook food at. It then starts generating a sine wave corresponding to that (110Hz for low temperatures, 220Hz for medium and 440Hz for high). It also starts generating a second wave which starts from a lower frequency and approches the frequency of the first wave based on the temperature of the pan. When the two waves are very close in frequency ,they generate beats which act as a natural alarm system.

Simultaneously the Plank inside the device vibrates according to the temperature of the utensil which gives another layer of feedback. Through use , a sense of the cooking process can be got just by touching and hearing the HaptiCook device.
